Huang Lian, alias Wei Lian, chicken feet even. Can purify fire, detoxify, heat, dampness; governance temperature sickness heat Sheng upset, vomiting blood, blood stasis, hot and humid full vomiting, dysentery, enteritis, red eyes and throat, mouth sores, otitis media, sore throat, yellow water Sore; clinical observation shows that there is a significant effect on type II diabetes. First, scaffolding Under normal circumstances, Huang Lianyi is cultivated in an area 800-1800 meters above sea level. Because of its pleasing shade, the degree of shading required is about 60%-80%, so it should be sheltered. In the past, wood was used for scaffolding, and there was an “acre (667 square meters) of Coptis roots with three acres of wood.” This is undoubtedly a destructive effect on the environment. After summing up the cultivation experience of Xinwu Village farmers in Fengmu Township, the scientific and technical personnel of the Huangshui Town Agricultural Service Training Center in Chongqing City applied for a patented bamboo-wood-cultivated mature soil technology and obtained approval from the State Patent Office. In the fifth, sixth and seventh months of the lunar calendar, the selected parcels of land were sprayed with Roundup, Nongwang, Glyphosate, and Gram-free. They were used for weed control. After one week, the land could be ploughed and then pressed. 3 meters 4 meters in size, buried cement piles or plastic piles, people soil depth of about 50 cm, about 1.7 meters high ground piles. After the pile is planted, take the wire or No.10) as a rake, then use a small wire to pull the net horizontally, and finally cover the shade net. In areas where there is a lot of animal damage, the sheds on the shed must be prepared. Second, planting 1. Planting time. Three times a year can be planted: In the first period, after the snow was sped in February-March, before the new leaves of Coptis chinensis were grown, the survival rate was high after transplanting. New leaves were soon after transplanting, new roots were grown, and growth was good. After the death, there is less dead seedling and it is better to plant the company for a long time. The masses call it "planting old leaves." The second period is from May to June. At this time, the new leaf has grown, the seedlings are larger, the survival rate after planting is high, and the growth is also good. The masses call it “planting and planting seedlings”. However, it should not be later than July because of the high temperatures in July. After the planting, there are many dead plants, severe dens, and poor growth. In the third period, from September to October, it entered the frosty period shortly after planting. It took root in an unstable state, and it was often frozen in winter and spring. It was susceptible to freezing and seedlings, and its survival rate was low. It was planted at this time in a low-temperature, no-freezing area. 2. Prepare seedlings. Before planting, pull a thick seedling from the seedbed. When raising the seedlings, use the right index finger and thumb to pinch the roots of the seedlings to pull up, shake off the dirt, put it into the left hand, place the roots on the side of the thumb, put the heads neatly, the roots must be straightened, and do not bend, 100 bundles into one Put. When the seedlings are rooted, they are damaged and lost their vitality. After planting, new roots must be regenerated. Therefore, long fibrous roots should be cut at 1 cm from the head before planting. If transplanting is to be carried out using the "through-rod method", the fibrous roots should be longer, about 1.2-2 cm. After shearing fibrous roots, water is used to wash the soil on the roots of the seedlings, and the operation is convenient. The roots and roots are easily contacted with the soil to induce new roots. At the same time, the seedlings absorb water. When the seedlings are planted, they are fresh and easy to survive after planting. Normally, they are pulled in the morning and planted in the afternoon. They are best planted on the same day. If they are not planted, they should be planted in a damp place. The next day, they must still be soaked in water before planting. Immersion of 1-2:500 kg aqueous solution of ammonium molybdate for 2 hours can promote rooting of the seedlings and accelerate growth. Immersion of the roots with potassium permanganate 0.5-1:500 kg aqueous solution for 2 hours also accelerates hair rooting and growth. effect. 3. Planting methods. Seedlings must be planted on a cloudy or sunny day. It should not be carried out on a rainy day, because the rainy days will step on the surface and make the seedlings muddy and difficult to survive. There are three kinds of planting methods: one is to plant a back knife, and the tool is a small heart-shaped shovel with a special wooden handle. When planting the right hand holding a shovel, and use the big, food, middle finger and take a seedling, the left hand to take a seedling from the right hand, with the big, food, middle finger to hold the upper part of the seedlings, and immediately insert the shovel into the soil, deep 4 -6 cm, pull 2-3 cm to chest, make a small hole, insert the seedling into the hole, remove the spatula immediately, push the soil forward to cover the hole, press the seedling with shovel back. From the top to the bottom, you planted and retreated, and you loosen the soil and flatten the footprints. The planting seedlings should not be too shallow. Usually, the seedlings of the appropriate age should be completely immersed in the leaves below, and the maximum depth should not exceed 6 cm. The easy-to-live, row spacing is usually 10 cm, square planting, and 5.5 to 60,000 plants per 667 square meters can be planted. The second is to kill the knife, that is, with a shovel to suppress the seedlings to be inserted straight into the soil. This method of planting is fast, but the survival rate is not as high as that of planting a back knife, and it is generally less used. The third is to plant the stem, planting it with the seedlings in one hand, pressing the other index finger to press the roots, inserting the soil, rotating the index finger a little, and pulling out the fingers, then push the soil to cover the finger holes. This method is faster and has a higher survival rate. Third, management 1. Make up seedlings. After planting, there are often varying degrees of dead seedlings. The first, second and third year after planting, the seedlings die for about 10% each year. The seedlings should be replanted in a timely manner. Generally, the seedlings are planted twice, the first time in the autumn of that year, The same age and strong seedlings are used to make up seedlings, and transplanting with soil is easier to survive. The second time the seedlings were released after the second year of snowification, the new leaves did not occur. In the large mountain areas that are frozen in winter, the seedlings planted in the fall of the first year are often arched out of the ground. Therefore, it is necessary to check in detail after the snowing. The dead seedlings were found to be supplemented. If seedlings are found to be lacking afterwards, they should be transplanted with the same seedlings as the seedlings, so that the growth is consistent after planting. 2. weeding. Due to the adoption of pre-emergence weed control, it should be combined with chemical weed control. In the year of planting and the following year, weeding is carried out 4-5 times a year, and the third and fourth years are 3-4 times a year, and the fifth year is 1 time, each time in grass. When there are 2-3 leaves, 250 grams of prometryne, 25-30 grams of simazine, and 2 packets of rice field (Yeoncheon) are used (only one of them is used when three drugs are administered), and 20- 30 kilograms of sand or phosphate fertilizer is mixed in sunny afternoons or evenings, and evenly spread on 667 square meters of yellow soil (only the net area of ​​the car), and use bamboo rafts or branches to fall into the ground. Then, carefully observe if there is no net weeds removed manually. 3. top dressing. Within 2-3 days after planting, topdressing should be applied once, with thin pig manure or cake water, or about 1,000 kg per crush of compost or manure. This time, the fertilizer was called "knife-knife fat," which allowed the seedlings to grow rapidly after they survived. In the September-October period of the year, the second, third, fourth and fifth years of spring harvesting in May and the second, third and fourth year of fall from September to October, each fertilizer should be applied once, for a total of eight times. For every 667 square meters of manure, 1,000 kg of human and animal manure and 20-30 kilograms of superphosphate are used for spring top dressing. Mix well with fine soil or fine compost, and apply fine bamboo sticks to remove the fertilizer attached to the leaves. In the autumn, the fertilizer is mainly farmyard manure, and it also uses fertilizers such as fire ash and oil cakes. The fertilizer should be fully cooked and smashed, and the mango flour should be removed. The thickness is about 1 centimeter, and the dosage is 1500-2000 kilograms per 667 square meters. If the fertilizer is insufficient, Use humus or earth fertilizer instead of a part. The amount of fertilizer should increase year by year. Dry fertilizer should be applied from low to high to spread fertilizer so as not to pile up or cover the leaves. The upper part of the slope and the edge of the slope are vulnerable to rain erosion. The fertility is poor and some should be applied. The rhizomes of Coptis chinensis grow upward and form stem sections every year. In order to increase the yield, the soil should be cultivated after the second, third and fourth fall seasons, and the humus soil collected nearby should be carefully removed and then removed. The second or third year is about 1 centimeter thick, which is called "flower mud"; the fourth year is about 1.5 centimeters thick, and it is called "full of mud". The soil should be uniform, and it should not be too thick, otherwise the roots and stems will be long and the quality will be reduced. 4. Balanced fertilization. On the basis of topdressing with fertilizers, in order to increase production, the vast number of farmers have applied chemical fertilizers to promote their growth after each weeding. In a comparative test, 50 kg of superphosphate and 10 kg of ammonium bicarbonate were applied at an optimal ratio every 667 square meters.
