What problems are often encountered in the cultivation of volvariella volvacea

1. The emergence of group mushroom sowing amount is too large, uneven sowing, will lead to the emergence of group mushroom. Therefore, the sowing rate should be controlled at 0.2-0.3 kg / m2. The sowing method can be layered sowing, mixed sowing or sowing, preferably without hole sowing. 2. If the aging strain is used, although the germination and colonization of the hyphae are normal, the yield of the first tide mushroom is also good. However, the yield of the second and third tide mushroom decreased significantly, and the overall yield decreased. Therefore, attention must be paid to the purchase of bacteria. 3. Excessive temperature difference leads to the death of small mushroom buds during the occurrence of fruiting body, ventilation and water spraying management must keep the cultivation environment as constant as possible, ventilation can only be carried out slowly, and pay close attention to the sudden change of climate. Window ventilation is strictly forbidden in windy days. When spraying water, we should also pay attention to the use of water temperature is consistent with the room temperature. 4. when the culture material is acidified and acidified, the growth of mycelium is weak, there is no sense of gloss, the occurrence of fruiting body is few and small, and it is easy to break the membrane and open the umbrella. At the same time, a large number of ghost umbrellas occurred. In order to prevent acidification, in addition to adjusting the pH value when preparing the culture material, the water management after sowing should be changed to spray 0.5% lime water. 5. When the culture material is too loose, the phenomenon is serious, resulting in mycelium fracture, thinning of the culture material and reduction of mushroom production. Therefore, after going to bed and sowing, we must pay attention to slightly compacting the culture material. If it is cultivated by stacking method, the pile shape should be low rather than high. 6. The use of deteriorating raw materials or culture materials for fermentation and disinfection of diseases and insect pests can lead to the breeding of a large number of miscellaneous bacteria and pests. Make a large number of young mushrooms on the bed die, rigid, rotten or teratogenic.
