How to prevent the occurrence of dead mushroom in mushroom cultivation
(1) scientifically and rationally allocate the culture materials to make the C / N ratio reach 28: 30, and do a good job of composting; second, we should select high-quality bacteria to eliminate aging and polluted bacteria in time; create conditions suitable for mycelium growth and development, and strictly prevent high temperature culture; third, during the mushroom period, we should pay close attention to the changes of the weather, adjust the greenhouse temperature according to the air temperature, strengthen ventilation, and strictly prevent the phenomenon of high temperature in the greenhouse. Fourth, pay attention to the mushroom shed often ventilated (- 2Mui 3 times a day). When the temperature is high, ventilation should be carried out in the morning and evening or at night to keep the air fresh. Fifth, watch the mushroom with water to avoid drowning the mushroom; sixth, after covering the soil, we should reasonably control the temperature, maintain the appropriate humidity of the soil layer, promote the growth of hyphae to the overlying soil layer, and make it change from vegetative growth to reproductive growth as soon as possible, so that the fruiting body-shaped part is between the coarse soil layer and the fine soil layer to prevent it from being too high or too low. 7. In production, we should adhere to the comprehensive control principle of "giving priority to control and supplemented by chemicals", prevent diseases and pests from being brought into the mushroom bed with the culture materials, eliminate the sources of diseases and insect pests in the covered soil, and thoroughly remove pathogenic bacteria and pests in the mushroom sheds. Create environmental conditions suitable for the growth of mushrooms. After the occurrence of diseases and insect pests, diseased mushrooms and dead mushrooms should be eliminated in time, and drugs should be used for prevention and control, so as to avoid spread. Eighth, when picking mushrooms, the action should be light and thin, in order to avoid man-made injury.

Often make mistakes in mushroom planting
When strawberry is cultivated in a small arch shed, the plant grows healthily, it can mature 19-22 days ahead of time, the harvest time is 13 days longer than that of open-field cultivation, and the total yield is 17% higher than that of open-field cultivation. The main points of cultivation techniques are as follows: first, the small arch shed can be set according to the width of two cultivation beds (about 3m wide). Insert the two ends of the bamboo slices or wooden poles into the outer edge of the back of the north and south border, insert one every 0.5m along the length of the border, and properly bury the column support on the back-death of the middle border, so that the height of the middle arch of the scaffolding is 1m, and the length of the shed is 10m 20m.

Fertilization techniques in Mushroom cultivation
Mushroom growth needs more nutrients, if the nutrition is not available for a while, the fruiting body will grow poorly, especially in the later stage, there will be premature senility. Especially in the case of poor quality of culture material, less manure and more grass, and thin material layer, it will obviously affect the yield and quality. Therefore, in the later stage of mushroom growth, timely and appropriate amount of topdressing is beneficial to improve the yield and quality. However, mushroom topdressing can only play an auxiliary role, and attention must be paid to the effect to prevent the breeding of miscellaneous bacteria caused by improper topdressing. In addition, it is necessary to know the concentration and dosage of topdressing.
