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 in 4 days after sowing, ventilation at about 10:00 every day for 30 minutes, with the increase in the amount of mycelium and the emergence of a large number of "needle mushrooms", the ventilation time should be gradually extended to 2 hours a day.
Fourth, to timely adjust the temperature when the temperature is low in winter, we should take measures such as double-layer film covering to keep warm, and when the summer temperature is high, we should pay attention to spraying water and setting up a shed to shade and cool down.
Fifth, we should pay attention to water spraying in the morning and evening, and the water temperature should be about 30 ℃.
Sixth, the humidity is suitable for the water content of the general culture material is 70%, and the air relative humidity during the mycelium growth period is 80%. The air relative humidity should be kept at 90% during the fruiting body growth stage.

Cultivation and Management techniques of Pleurotus ostreatus
Pleurotus ostreatus, also known as Pleurotus ostreatus, is a rare, precious and delicious edible fungus.

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 relative humidity of the air can be increased to about 90%.
