Pan-style cultivation disc culture is created in China, generally used by farmers, is currently the main cultivation mode of China's mushroom production area. One peasant household produces 3,000 kinds of mushroom (curtain), and needs 80 rooms for bacteria, and 100 rooms for mushrooms. Two oysters per year can create 20,000 yuan.

1. Seasonal arrangement of plucked mushrooms is suitable for growing in low temperature and moist environment, so it is mostly cultivated in the north near the coast. The frost-free period in the northern region is short, and the cultivation mode for regular spring planting and autumn harvesting only produces one cycle per year and the utilization rate of equipment is low. Heilongjiang Muling County Institute of Medicinal and Medicinal Plants has proved that after 2 years of cultivation practice, it is feasible to cultivate 2 1 in 1 year.

The average temperature in the spring and autumn in the north is about 10°C, which is a time for fruiting and a good time for slippery mushrooms. According to climatic conditions, the time for adjusting the mushroom and the mushroom is shown in Table 24-1.

Table 24-1 Seasonal arrangement of 1 year-old oyster mushroom 2 Seasonal arrangement Inoculation Fungi springing out Spring seedlings Marching to April April to August September to October Autumn seeding Spring October to November 12 From March to March, April to June, the spring arrangement is to mushroom after mushrooming, and the autumn arrangement is to mushroom after the first mushroom, that is, spring and autumn will fall out and autumn will spring out. Every week, two times a year.

Spring infestation at a lower temperature (March-April) will not only help prevent pollution, but also help germs. During the spring and summer period (April-August), the bacteria are kept in a single layer on the culturing shelf, or placed on the culturing shelf, and the worms are dumped once every half a month to avoid burning bacteria. July-August mushrooming room to cover the straw, ventilation and temperature control, safe summer, the mycelium fully accumulate nutrition during this period. In September, the film was sprayed with water and the mushrooms were finished. At the end of October, the mushroom was finished.

Autumn seedlings are vaccinated from October to November. Low temperatures do not easily contaminate germs. Cocoon can maintain bacteria, each 10 to 12-storey high, at room temperature maintained at 15 ~ 20 °C, pour it once a month, in order to make the hair evenly. After the mycelium is full, it can be stacked around 0°C from December to March. When the temperature rises above 10°C in April, you can add mushrooms to the shelf and end the mushrooming at the end of June.

2. There are differences in the temperature requirements for the fruiting bodies of the broiler species of the species selection. According to these differences, the phoenix mushrooms can be divided into 4 types:

Very early maturing 20 °C; early maturing 15 °C; medium maturing l0 °C; late maturing l0 °C below.

It can be seen that the temperatures required for the formation of fruit body primordia in the broilers and the late-maturing species are lower. Oyu No. 2 and No. 3, both of which are mid-late seedlings, have concentrated time for fruiting and are conducive to harvesting, processing, and arrangement of shiitake mushrooms.

Under normal circumstances, the color of the mushroom varies depending on the species. The early-inoculation umbrella is orange-red, and the medium- and late-maturing varieties are red-brown. The stipe of early maturing varieties was finer and longer than that of late-maturing varieties, and the mucilage on the latter was more than the former. The early maturing varieties had normal growth around 15°C, and the mid-late maturing varieties had good growth around l0°C.

The northern part of China belongs to the continental climate. In summer and autumn, the temperature changes greatly. The natural temperature is used for mushroom cultivation. Different types of bacteria are selected according to different cultivation methods.

3. Tray making specifications are generally 55cm35cm. The materials used to make the trays can be adapted to local conditions. Sorghum stalks, corn stalks, and waste wood can all be made into trays. No matter which kind of material, the trays made are required to be smooth and thorn-free, so as not to break the plastic film. The practice of corn stalks trays is to first smash the leaves on the stalks and use a knife to flatten the pods at the stalk knots and cut them to the desired length. On the corn stalks, two holes are inserted at a distance of 30 cm and fixed with two hard branches. One tray needs 7-8 pieces of corn stalks. See Figure 24-3 for the straw tray or wood pallet used for pan-tree cultivation.

Figure 24-3 straw tray or wood tray 4. Raw material formulation raw materials were prepared as follows: (1) wood chips 89%, wheat bran (rice bran) 10%, gypsum 1%; (2) wood chips 49%, crop straw powder 40%, wheat bran (rice bran) 10%, gypsum 1%; (3) corn cob Powder 69%, bean powder 20%, wheat bran (rice bran) 10%, gypsum 1%; (4) wood chips 79%, sugar beet pulp 15%, wheat bran 5%, gypsum 1%.

The raw materials needed for the above formula are mixed, and the water is stuffed with water for 2-3 hours and then mixed well. The materials are grasped by hand and the water content between the fingers is about 60-61% of water content. Steam will increase the moisture in the culture by 2% to 62-63.

In the production practice, the following issues must be noted: First, to increase the amount of wheat bran or rice bran used to increase production, the results are counterproductive, not only did not increase production, but due to bacterial contamination of bacteria and reduce production.

The second is that it is very fast and the ingredients are “ning dry and not wet”. The result is that there is a lack of water in the material and it is difficult to produce mushrooms later.

The third is that the culture material contains more than 63% of water, causing an oxygen-deficient environment and difficulty in germination, which in turn breeds bacterial culture materials that become acidic.

5. Sterilization of sterilized oyster mushrooms produced by steam sterilization is different from other varieties, and the operation of the steamer in the steamer is as follows: After boiling the pot of water, sprinkle 5-7cm thick dry material on the bottom of steamer to absorb the dripping of the upper part. Condensate water, and then sprinkle the material with normal moisture content to the place where the hot air emerges, must strictly follow the "see the gas to spread the material" the request carries on, forbids the material to quickly pour into the drawer. Otherwise there will be "caught raw material". The drawer is filled with 2 layers of sacks, counting from the time when a lot of hot air escapes. Steaming is continued for 2 hours, and after 40 minutes of stoppage, the temperature of the material is about 90°C. If it is less than 70°C, it is easy to infect bacteria after inoculation.

Need to be clear, normal pressure steam material for 2 hours, can only kill the vegetative bacteria, can not kill spores, so the culture material must be pre-constructed or fermented for 2 days, so that all the bacteria within the material in an active state to facilitate the killing Off.

If the air pressure is maintained at 100°C for more than 8 hours at atmospheric pressure, all bacteria including spores can be killed, so the culture materials do not have to be pre-constructed or fermented.

6. Loading inoculation wooden frame size: 55cm35cm8cm; scraper size: 25cm12cm (Fig. 24-4); polypropylene coating: 105cm100cm0.003cm.

Figure 24-4 Tooling Tools (1) Loading Fill the steamed culture into the plastic film inside the wooden frame, each material is 4.5kg, and the thickness is 4.0-4.5cm after compaction. Scrape the medium with a squeegee to slightly raise the surface of the material to avoid disc area water.

Some growers advocate that the cultivation materials should be thicker, and think that such nutrients are sufficient, and the latter few mushrooms are robust and have a high yield; while some growers believe that the suitable fruiting period is limited, and the medium thicker than the last year Raw materials are wasted. The thickness of the culture block is 3.0-3.5 cm. These two arguments have some truth, but they all have a lot of one-sidedness. The former puts the culture block too thick, when the temperature rises, the bacteria blocks become dissatisfied, and it is easy to cause contamination with bacteria. When it comes to mushrooming, it causes waste of raw materials. The latter because the culture block is too thin, it is not conducive to water conservation, but also when the second and third oyster mushroom nutrient deficiency, the lean body of the mushroom, thereby affecting the yield and quality. According to several years of production practice, the thickness is still about 4.5 cm.

(2) The temperature of inoculum plate is cooled to below 25°C to inoculate. Some producers believe that hand-testing materials do not feel hot to inoculate. This method is in fact unreliable, strains are often subject to high temperature damage, germination and disease resistance are reduced, bacteria are slow and easy to stain bacteria.

The inoculation room is sterilized by conventional methods. 5 people were vaccinated in each group, of which 2 were packaged and transferred, 3 were planted, seeded and sowed. Use a clean hand to carefully chop the strains into chunks of corn kernel size. Do not rub them with your hands. Open the tray, quickly and evenly sprinkle a layer of bacteria, gently compacted, so that bacteria and the full contact with the material surface, in order to facilitate the germination of species to eat.

7. Fungi management and fungicide management is an important part of the mushroom cultivation process. Based on the selection of good strains, strict steam sterilization, and careful inoculation, coupled with good management measures, the cultivation of pl Possible. Ignoring management and doing the first few things well will not receive the expected results. Some growers only pay attention to the management of previous work, and think that the inoculation is finished, and it is not necessary to manage them until the fall to wait for mushroom collection, and there is a tendency to severely neglect management. Practice has proved that the results of careful management and neglect of management are very different. The same size of mushroom plate, properly managed, each piece can produce 2 kilograms of fresh mushrooms; and the poor management of only 0.5 kilograms! Some cultivation households due to bacteria early neglect management caused by "burning" and suffered losses. According to the different characteristics of the mycelial growth stages of the mushroom, the management of the mushroom was divided into the early stage of germination, the middle period of germination, and the late stage of germination.

(1) The initial stage of germination is from the initial stage of inoculation after inoculation to the surface of the whole mycelial disc. The purpose of this period of management is to restore the growth of mycelium as soon as possible, and quickly fill the surface of the bacteria plate, the management should focus on insulation and ventilation. After inoculation, the bacterial plate can not be directly placed on the culture rack due to the low temperature inside and outside the mushroom house at night, so as to prevent the bacteria plate from being frozen. It is usually to select a mushroom house or an idle house at a temperature of 2 to 4°C. Put each of the 7 plates together and cover them with a cotton or straw curtain to keep the plate temperature at 2-4°C. Needs light. Once every 5 days, pour the upper plate to the bottom and the bottom to the top. At this stage, in addition to maintaining the minimum bacterial temperature of the bacterial plate, attention should also be paid to the ventilation of the site. When the outdoor temperature is low (-5 to 3°C), the plastic film opening the bottom corner of the shed is ventilated for 1 hour every 3 to 5 days or the window of the open house is ventilated for 1 hour. After 5 to 7 days after inoculation, the bacterial seed germination became white, indicating that the hyphae had returned to normal growth. After 10 to 15 days at 4 to 8°C, the surface of the disk was covered with white hyphae and began to grow deep into the medium. The fungal growth was completed at the beginning. Although the initial period of germination is short, the success or failure of cultivation is extremely important, because at this time, the temperature changes greatly and there is a possibility of rapid increase. Once the temperature rises, the bacterial plate cannot be scattered in time. The higher the temperature, the more prosperous the mycelium grows. The heat generated by the mycelial respiration is diffused slowly by the film, and after a few days, the medium becomes acidic and there is a so-called “burning” phenomenon. Therefore, the management of the inoculation and the early stage of germination are intertwined. At the time, they must be clear-headed and avoid losing sight of one another.

(2) Medium-term management of germination is performed from the surface of the culture medium of the strain to the entire medium for the middle period of germination. During this period, the management will focus on the improvement of ventilation in the mushroom house to ensure that the entire medium is filled within the predetermined time limit of the mushroom. In the middle of germination, the bacterial plate should be on the shelves. Some people think that after the inoculation, the bacterial growth time is longer, the culture medium is compacted, and the yield is high. The length of the pile-up bacteria should be determined according to the speed at which the temperature rises, and the stacking time cannot be dragged on for too long. The experimental plant of the Dandong Forestry Research Institute has done the following tests: After the inoculation, the bacterial plate was divided into 2 groups of bacteria, the first group of 10 dishes, after the initial stage of germination, placed on the culture shelf to continue to grow bacteria, before mushrooming, The yield was 100%; in the second group, the 1O plate, piled with bacteria, was not moved to the culture shelf until late in the germination period, and the yield was only 40%. This result shows that the long time of the pile-up bacteria is very unfavorable to the normal growth of the mycelia in the plate. The reason is that the hypoxic mycelium weakens and it is easy to contaminate the bacteria. After 20 days of inoculation, the temperature gradually increased and the mycelium grew more vigorously. The ventilation of the cultivation site must be strengthened. The mushroom house should be ventilated every 1-2 days. At the same time, the top of the simple mushroom house should be covered with shading items such as straw and curtains. Curtains, etc., to prevent a sudden rise in the temperature of the sun mushroom house. This stage is the period of multiple bacterial contamination, so always check the plate, if the individual plate found contamination of bacteria, belonging to Trichoderma, Rhizopus, Mucor pollution, can be moved to a cool, ventilated place to continue to cultivate. About 40 days after inoculation, the bacteria plate should be changed from top to bottom. An effective method for treating bacterial plates contaminated with bacteria is described (“Pleurotus ostreatus cultivation techniques”, edited by Zhu Ke): Contaminated bacterial plates are buried in soil, and when the temperature begins to fall in autumn, mushrooms are removed again. The specific approach is to choose a well-drained area, first dig a drainage trench that is 20 centimeters deep and 20 centimeters wide, store the soil excavated from the trenches where the culture blocks are to be placed, and develop a platform that will be cultivated after being slightly flattened. Place the block on the soil platform and dig the same drainage ditch on the other side. Cover the soil with the dirt dish. Cover the soil with a thickness of 10 cm. Use soil tightly on both sides of the plate. Contaminated with Trichoderma and Penicillium If it is a part, the plastic film of the contaminated site can be gently opened, and a layer of lime powder can be sprinkled on it again to re-encapsulate it, bury it in soil, and then remove the cultured bacteria and produce mushrooms in the fall. In addition to this, do not open the film casually during the incubation period to prevent breeding of bacteria or insects during the summer. If most of the bacterial plates are contaminated with bacteria, it is difficult for the mycelium to resume growth. These bacteria plates should be promptly moved away from the mushroom house and buried in a deep pit with a fire or a 1-meter-digging area.

(3) The later period of post-sporation administration means that the mycelium is covered with the entire medium to the time when the waxy layer is formed. The difference between the management of this period and the previous two periods is that the temperature of the mushroom room is properly increased to maintain 18 to 22°C.

In the case of a normal rise in ambient air temperature, it takes 50 to 60 days from the inoculation of mycelium to the entire culture medium. At this time, the mycelium and the culture medium are integrated into one body. The two hands can hold the bacterium and not break it. Beads and yellow-brown secretions began to appear on the surface of the culture medium. In this case, it is necessary to add scattered light to the bacteria plate, and to strengthen the ventilation of the mushroom house. Generally, the insulation curtain around the mushroom house is removed, if it is cultivated in an empty house. Doors and windows should be opened and regular ventilation should be maintained to promote the transformation of surface mycelium and gradually form a waxy layer.

The formation of a waxy layer has a great influence on the yield results. The normal waxy layer is orange and reddish-brown, with a thickness of 0.5-0.8 mm. The waxy layer protects the intracellular hyphae, preventing evaporation of water and preventing invasion of external pests and germs. The formation of a good waxy layer is also an important symbol of robust and high-yield mycelium. Some cultivators often ignore the management work at this stage, thinking that as long as the silk is full of plates. After autumn, there will be better yields. Practice has proved that: The formation of waxy layer is not good, the mycelium within the bacteria plate is low resistance to bacteria, easy to rot. There are three factors affecting the formation of the waxy layer: First, inferior strains, weak mycelium, generally not easy to form a waxy layer; Second, scattered light intensity is not enough. After the mycelium is filled with medium, scattered light should be given in time. But the luminosity should be appropriate. The stronger the light, the thicker the waxy layer, and sometimes 1.0-1.5 cm thick. This waxy layer consumes too much nutrients, which is not conducive to the absorption of water, and often affects the yield.

(4) After the management of the waxy layer on the surface of the bacterial disk over the summer, the germination of the bacteria has ended, and the mycelium has basically reached a physiological maturity, and it has already had the ability to produce mushrooms. However, at this time, when the summer temperature is high, the ambient temperature is high and there is no condition for fruiting. Therefore, it is necessary to use more summers. The main task of the over-summer management is to maintain the degree of shade of the mushroom house and increase the shade of the mushroom house. During this period, the temperature of the mushroom room should be controlled below 26°C. If the temperature exceeds 26°C, you can take measures to reduce the temperature of the cooling water while strengthening the ventilation. The specific approach is to lay a layer of sand on each road in the mushroom house. 2-3 cm, then spray well water into the room and ground of the mushroom house to play a role in cooling the mushroom house. If you do not take measures to reduce the temperature during the high temperature, if the bacteria plate is exposed to high temperatures for a long time, the mycelia will be damaged and the mushrooming ability will be greatly reduced. Into the management of mushroom on the eve of mid-August, the entire bacterial plate should be checked again, if there is a whole dish of contaminated bacteria, should be picked out in time to deal with, for the local contamination of the mushroom plate can be removed from the mushroom house and the normal complete plate Separate, separate management.

8. Before the mushroom is inoculated, the mushroom is inoculated, and after the inoculation of the spring and the summer, the natural temperature falls below 2O°C in the fall, and the mushrooming stage can be entered. The management steps are as follows:

(1) Open-faced Heilongjiang and Jilin In mid-August, in the rest of the Great Wall, from late August to early September, the average temperature can generally drop below 20°C, at which point the opening conditions are met. Before the operation, check and sort the plates.

The criteria for classification are mainly based on whether or not the waxy layer is formed on the bacteria plate, the thickness of the waxy layer, and the degree of contamination of the bacteria: a waxy layer has formed, the plate is complete, and the hand feels elastic is classified as a class; no formation or only partial A thin layer of waxy layer is formed, and the discs are completely flexible and contain no bacterial contamination. The bacterial plates contaminated with bacteria are classified into three types.

For the second type of bacterial plate that has not formed a waxy layer, it should be moved to a place where the temperature difference is large and there is scattered light, the film is opened slightly, and the whole plastic film can also be removed to put the plate in the culture rack, and then the plastic film is cultivated. To accelerate the formation of a waxy layer. The bacterial plates that are infected with the bacteria should be managed separately from the normal ones so as to prevent the contamination of the bacteria. At the same time, the mushroom house should be cleaned and disinfected to make it clean and clean. If there are mushroom mosquitoes or mushroom fly, light can be used to trap or kill mosquitoes and flies with mosquito repellent spray.

Because of the waxy layer, it is not conducive to moisture and air entering the plate. Can be self-made blade, every 3 cm in the disk cut wax layer, the depth varies depending on the thickness of the wax layer, thick strokes O.5 cm deep, thin strokes 0.2 cm deep, generally designated 6 to 7 lines . After drawing the plate, the fungus plate should continue to cover the plastic film. After 5 days, the new hyphae should be grown on the scratches before the sprinkler can be managed, and the water can not be sprayed on the plate immediately after the drawing. Otherwise, because the surface mycelium wound has not healed, the water spray is suddenly stimulated and the hypha shrinks, which not only delays the time of mushrooming, but also affects the yield.

(2) Spraying water on mushrooms can induce the formation of fruit body primordia. When the water is too cold, it should be placed in the mushroom house for a period of time before use, so that its temperature is consistent with the temperature in the mushroom house; tap water containing bleaching powder should be put in the tank or pool for a period of time to release the chlorine gas. Reuse; Sources contaminated with industrial and domestic sewage or sources containing salt, acids, and alkalis should not be used. The spray tool should use a sprayer and the sprayed droplets should be fine and uniform. After the water spray, the surface of the bacteria plate cannot collect water.

If the temperature is not stable, it will rise after falling, causing the mushroom room temperature to exceed 2O°C, sometimes as high as 25°C, and spraying of water should be stopped to prevent the occurrence of rotten discs and miscellaneous bacteria. At this moment, after the water on the surface of the bacteria plate is evaporated, temporarily cover it with a plastic film and spray water to the ground and space to reduce the temperature in the mushroom house. When the temperature drops to 15 to 20°C after the high-temperature weather, spray 40 to 50 ml of water per day to the bacteria plate, mainly for evening spraying.

When there is a small amount of primordium on the surface of the bacteria plate, spraying water to the surface of the plate is temporarily stopped. Water is only sprayed to the ground and space, and the humidity in the mushroom house is maintained at about 90%. When the plate is cooled, water is sprayed onto the plate surface again. neat.

The primordium of the fruiting mushroom fruiting body was formed as milky white granules when it was formed. It turned yellow-brown or reddish-brown after 1-2 days. When young mushrooms with mushroom umbrellas and stipe are formed, they can be transferred into mushroom management.

(3) Management of mushroom management at the time of mushrooming is management after the formation of the young mushroom and before harvesting. The main points are as follows: 1 Humidity Primordium develops into a normal fruiting body and is affected by the dual factors of water content in the medium and relative humidity in the air. The growth of the fruiting body requires that the water content of the culture medium is above 70%, and the relative humidity of the air is above 85%.

Increasing the amount of water sprayed at the time of mushrooming is often more than a disadvantage. When the water was sprayed too much, the color of the plate was dark reddish-brown and dull. The fruiting bodies grew slowly and the color was dark reddish-brown with a thick mucus layer. In addition, when the water in the medium is too large, especially under no-ventilation conditions, in addition to the contamination of the bacteria, insects such as mushrooms, moths, and nematodes are also induced. Insect pests mainly swallow hyphae, making the culture block loose, excessive water absorption and blackening, and eventually causing no mushrooms. In short, the water management during the fruiting period is mainly to maintain the relative humidity of the air, and water is sprayed on the plate surface according to the growth of the mushroom body. The temperature of the mushroom mushroom requires no umbrella. The weight of a mushroom body has a large proportion of stipe. Therefore, in the mushroom management, it is necessary to control the opening of the mushroom as much as possible in order to increase the ratio of the stipe in the total yield.

The temperature is suitable for the growth of the stipe to increase the yield. Generally, the required temperature for the development of the stipe is slightly higher than that of the primordium. When the mushroom tray is relatively neat, it can be used to temporarily control the ventilation and spray water for 1-2 days to increase the room temperature. If the mushroom is not neat, you can stop spraying the water on the primordial culture block for 1-2 days to increase the room temperature, and spray the water when the stem grows upward. If the temperature during the fruiting period is too high, the original primordium formed is small, and the mushroom umbrella is light in color and it is easy to open the umbrella.

3 When the light comes out of the mushroom, it must have scattered light and avoid direct light. If there are too many coverings on the top of the mushroom shed, the spacing between the sheds in the shed is too small, which will lead to insufficient light in the shed. The stipe of the mushroom body is long and curved, the mushroom color is light, the fruit body is small, and the umbrella is opened early. Therefore, during the fruiting period, it is necessary to appropriately reduce the roof cover to ensure that the plate has proper light. The light is too strong for the fruit body growth is also unfavorable, bacteria disc water easily lost, is not conducive to the normal growth of mushroom, a direct impact on production. The intensity of the scattered light in the fruiting process is preferably 700-800 Lux, which means that the light intensity of the newspaper body text can be clearly seen in the shelves.

The characteristics exhibited by the growth of the fruiting body of the mushroom are not completely determined by a single condition, but are the result of a combination of factors. See Table 24-2 for the effect of environmental conditions on the fruiting body of the fungus.

Table 24-2 Effect of environmental conditions on the fruiting body of the mushroom Pleurotus ostreatus Environmental conditions Bacteria Umbrella characteristics Stipe characteristics Other colors Glossy mucus Substrate too wet Deep without air drying Normal paint light Few mushroom development Slow temperature too long Easy light The temperature of the parasol is too low and there is no normal short and thick mushroom body development. Slow light is not enough. The light and slender, the light orientation mushroom is easy to open. The parachute is poorly ventilated. (4) The mushroom management period Mushroom roots, and stop spraying water to the bacteria plate, covered with plastic film, to prevent the surface of the disc surface dry, slightly raise the culture temperature, in order to facilitate the accumulation of more nutrients mycelium, a good oyster mushroom. The mushroom mycelium is organized to form the primordium. The moisture and nutrients it can use are supplied by the mycelium at the lower part of the primordium. This can be observed by splitting the part of the plate with long fruiting bodies and below the fruiting body. Obviously thicker white bunchy hyphae, but not the mushroom is still white flocculent hyphae, there is no door-colored bunchy hyphae, which requires the mushroom farmers in the cultivation of a mushroom After that, it is necessary to create conditions for the transformation of mycelium from reproductive growth to vegetative growth. After spraying water for 5-7 days, when new mycelium is produced on the surface of the bacteria plate, the plastic film is opened, water is sprayed into the space and the ground of the mushroom house, and the relative humidity reaches 85% to 90%. A few days later, there are new ones. Primordium formation.

At present, the cultivation of broilers in China is mainly based on natural temperature, bacteria, mushrooms, the use of strains are mainly mid-late maturing varieties, 10-15 °C temperature requirements for fruiting. However, it is only about one and a half months for suitable mushrooms to be grown. In order to fully increase the yield, when the temperature falls below 5°C, consider appropriate conditions for temperature increase to prolong the fruiting period. In recent years, the mushroom farmer has learned from the production practice to improve the mushroom room temperature experience, such as removing the cover on the top of the mushroom house during the day, using sunlight to increase the temperature of the mushroom house. When the sunlight passes west, cover the heat preservation curtain and so on. This will maintain the third oyster mushroom. If there is no mushroom plate, it is necessary to take measures to cover the winter. After the last mushroom is harvested, stop spraying and drying it for about 10 days to reduce the moisture content of the plate to avoid freezing damage during winter storage. After cleaning the bacterial plate, move it to a storage room between 0-2°C and wrap it with a plastic film to prevent it from drying out. In the next spring, when the temperature rises to 5°C, the plastic film is peeled off and the mushrooms are sprayed on the mushroom holder. Management measures are the same as before.

Frozen or completely blackened, scattered pieces of bacteria can not be mushroom. Therefore, check the bacterial plate before wintering. When the culture block is complete, the hand is elastic, and there is a large number of white hyphae on the section of the plate, all have the ability to produce mushrooms. On the contrary, if the plate is loose, scattered, and there is no white mycelium in the block and it is black, it will lose its ability to produce mushrooms and should be eliminated.
