Due to the different time of colonization of greenhouses and potted peppers, the growth environment of the color peppers varies, so the management focus is not the same, and the management of the farmers should not be handled in a nutshell so as not to affect the normal growth of the color peppers.
Determine the sticking method, reasonable pruning
For the color pepper planted in the greenhouse, the ground has been covered for a short period of time, and the ventilation and light transmission between the leaves of the plants are in good condition. At this time, the larger the leaf area, the more organic material the leaves produce, which is more conducive to the improvement of yield. Therefore, the first method of pruning can be used to prune. When the plants grow to a certain height and the leaves cover each other seriously in the next spring, the weakest branches on the plants can be removed.
For arched greenhouse, the management is relatively extensive, and no effective pruning has been carried out in the previous period. Now the planting branches have grown taller and the result volume is larger. Some weak branches may be removed to improve the ventilation and light transmission conditions between the plants. , to promote the improvement of production.
Reasonable fruit retention and promotion of yield increase
The greenhouse colonization during the peak period of greenhouse colonization was concentrated in August, and now it is entering the fruiting period, and the greenhouse pepper has entered the harvesting period.
In greenhouses, for pepper plants that are left under control, peppers and peppers on the plants can be removed in time to encourage ventilation and fruit setting. 4 The main branch leaves the fruit of the color pepper can leave 12 pieces of fruit or so, after removing the deformed fruit, the size of the fruit, you can take 8 fruits. This can greatly increase the yield of head pods, and appropriately extend the time to market, ensuring that the nutrient supply of the pepper is balanced and does not affect the fruiting of the second batch of fruits.
In the greenhouse, the current fruit is inflated. Zhou Zheng should be selected as the fruit shape. Others harvest the green fruit in time to reduce the burden on the plant and promote the rapid expansion of the upper fruit.
Root disease prevention and control are different
Dead pepper is one of the most troublesome problems for vegetable farmers. At present, the diseases caused by greenhouses and greenhouses are different from those of dead trees, and attention should be paid to prevention and control.
When the greenhouse pepper was planted, the disease caused by dead trees was mainly caused by Phytophthora root rot, Pythium root rot, etc.; In the flowering period, the disease caused by dead trees was mainly wilt disease and stem rot. Dead trees mainly rely on prevention. In the summer, soil treatment is required to increase the amount of fungicide. If no soil treatment is carried out, pepper plants should be promptly treated with norozole and DT to prevent disease. By the spring of next year, when the plant enters a large number of fruiting stages, wilt disease, bacterial wilt, etc., will also cause dead trees. At this time, biological bacterial fertilizer can be applied to sterilize bacteria.
Many of the dead trees that have recently appeared in the greenhouse are caused by rain and water, which are caused by roots and root rot. It is recommended to set up waterproof membranes on both sides of the arch shelter and to clear the flood prevention trenches around the shelter to prevent heavy rain from accumulating and flowing into the shed. In the event of heavy rainfall, the patrol will be promptly taken to the shed to block the loopholes (holes hit by rats, etc., can connect the inside and outside of the shed. If the vegetable farmer fails to find it, it will make the rain-proof facilities useless). If rainwater has entered the shed, it should be drained in time and sprayed with hymexazol, DT and other agents to prevent pathogens from infiltrating. For plants that have already emerged, remove the diseased plants in time, treat the soil with carbendazim, DT, etc., and raise the soil around the diseased hole to prevent the water from flowing through the diseased soil to spread pathogens when watering.
