What to do when dentate mushrooms appear?
The fruiting body of young mushroom develops normally, but the edge of the cap is like a serrated, convex and concave uneven. The cause of this disease is mainly caused by strong wind stimulation. The wind is strong, the humidity is less, the young Pleurotus ostreatus fruiting body is affected by these adverse environments, resulting in metabolic interference, some tissue cells on the edge of the cap are damaged, resulting in serrated Pleurotus ostreatus.
Prevention and control methods: windy weather, do not open tuyere or less tuyere, if urgent ventilation, the north wind only opens the south tuyere, the south wind only opens the north tuyere. At the same time, the amount of spraying water was increased to improve the humidity of the mushroom shed.

Eight key points to prevent mushroom wilt
1. Early prevention of mixing materials. When using corncob, wheat straw and rice straw as main materials, 5% wheat bran or 4% fermented livestock and poultry manure are added to the bottom; when using nitrogen-rich cotton husks as main materials, no nitrogen source can be added, but attention should be paid to controlling the harm of mites. Trichlorfon with 800 times liquid can be sprayed when mixing, and the effect is very good. two。 The acid and alkali are moderate. The amount of lime added to the ingredients should reach 5%, and after each harvest of mushrooms, 1% lime water or 4% plant ash water should be sprayed to increase the pH value. 3. Ventilation and penetration

How is the output of Pinellia ternata?
Pinellia ternata is usually propagated by tubers, which can be harvested three times a year, that is, the first harvest in April and around June 20; the second time on August 10-20 and the third time on September 10-15, that is, three times when plant buds mature and cultivate soil three times or take plant buds to plant separately, it is also a stage of growth, development and maturity of underground bulbs. However, the domestic species are usually harvested once after autumn, because Pinellia ternata continues to grow and expand the underground corms. In field management, plastic film can not only maintain soil moisture, but also increase the soil temperature by about 4 ℃.
