What to do when hollow mushrooms appear?
This situation is often accompanied by thin mushroom body, thin cover, rare mushroom production, often occurs in the later stage of mushroom emergence, insufficient water in the culture material, insufficient nutrition, low humidity, air relative humidity less than 80% for a long time, and maladjustment of cell elongation in the stalk.
Prevention method: after picking Pleurotus ostreatus, timely inject water and nutrient solution into the culture bag, or carry out soil-covering cultivation, the mushroom shed should be shaded and cooled, spray frequently when spraying water, and the air relative humidity can be increased to about 90%.

Six points should be done to prevent mushroom wilting.
First, to prevent the use of corncob, wheat straw and rice straw as the main ingredients, 5% wheat bran or 4% fermented livestock and poultry manure should be added. When using the cotton husk rich in nitrogen as the main material, the nitrogen source can not be added, but in order to control the harm of mites, 800 times liquid of trichlorfon can be sprayed when mixing the material. Second, the amount of lime added when the acid-base ingredients are moderate should reach 5%, and 1% lime water or 4% plant ash water should be sprayed every time the mushroom is harvested, so as to improve the pH value of the culture material. Third, ventilation should be carried out at about 10:00 every day for 4 days after sowing.

High-yield cultivation of Pleurotus ostreatus
Pleurotus ostreatus, also known as Pleurotus ostreatus, the raw materials used in cultivation are mainly sawdust, but also cultivated with wood sections, in a variety of ways. The development of Pleurotus ostreatus production is a rich project with low investment, quick effect, high yield, good benefit and low risk. The finished products of mushrooms can not only be sold domestically, but also be exported to earn foreign exchange, which is the way for mountain farmers to shake off poverty and become well-off. The main results are as follows: 1 the site should be cultivated in a place with flat terrain, good ventilation, clean environment and no pollution. The mushroom room can be framed with wooden poles and surrounded by plastic film or straw curtains.
