1. Mixing early defense. When corn cob, wheat straw and rice straw are used as main materials, 5% bran or 4% fermented and decomposed livestock manure is added at the bottom; when nitrogen-rich cotton seed crust is used as the main material, nitrogen source may not be added, but it is necessary to pay attention to control. Locust damage can be sprayed with 800 times the liquid trichlorfon during the mix, the effect is very good. 2 moderate acidity. When adding ingredients, the amount of lime to be added should reach 5%. After each mushroom is harvested, 1% of lime water or 4% of vegetation water should be sprayed to increase the pH. 3. Ventilation and ventilation. In the 4 days after sowing, the air was ventilated at about 10 o'clock every morning for half an hour. With the increase of the amount of hyphae and the emergence of a large number of "needles", the ventilation time was gradually extended to 2 hours per day. 4. Cooling insulation. When the temperature is low, two-layer coverings and other measures should be adopted to keep warm. During the summer heat, it is necessary to pay attention to water spraying and scaffolding to reduce the temperature, and to minimize the temperature difference in the mushroom house. 5. Spray water. Spray water should be carried out in the morning and evening. The water temperature should be about 30°C. 6. The humidity is suitable. The optimum amount of water for general culture materials is 70%, and the relative humidity of the mycelium during the growing period is 80%. It is advisable to maintain the relative humidity of the air in the fruit body growth stage at 90%. 7. The right mushroom. When picking, do not touch the young mushroom that is growing. If the mushrooms are crowded, you must wait until most of the mushrooms are mature. Hold one's hand in its growth position with one hand and lift the other with a mature mushroom to reduce damage to the mushroom. 8. Apply pesticides in time. When molds appear on the material surface, a layer of quicklime powder is sprinkled in the contaminated area. At the same time, ventilation and cooling are strengthened to prevent the spread of the bacteria.
