Moisturizing skills of Culture material of Pleurotus ostreatus
1. The bacteria stick wall is covered with soil to moisturize. Lay a thick 15~20cm ridge according to the length of the bacterial bag in the shed, remove the plastic bag and put it neatly on the ridge. Each row is covered with 1 layer of soil with thick 3~4cm. Spray water on both sides of the soil and smooth it with mud. Then discharge the second layer of bacterial sticks and cover the soil, which can discharge 6-9 layers, and the top layer should still be covered with soil and wiped flat. Spray water once behind the wall to make the covered soil absorb enough water. From now on, spray water every day to keep the soil moist, according to the routine management of mushrooms. This method can increase the yield of Pleurotus ostreatus by 50% to 90%.
two。 The mouth of the bag is covered with nutritious soil to moisturize. Nutrient soil formula: fertile soil 45kg, plant ash 5kg, mix well with appropriate amount of water, add water to grasp a handful of soil at a height of 1m to release, the soil can fall to the ground and spread out. When bagging, put 2~3cm thick nutritious soil at each end of the bag. During the mushroom period, the nutritious soil was sprayed with water once or twice a day, and the other management was routine. This method can increase the output by about 50%.
3. The sunny bed is covered with soil to moisturize. After bag planting Pleurotus ostreatus harvested a tide of mushrooms, take off the bag and sun for 1 or 2 days, so that the surface of the stick is covered with a layer of skin, so as to prevent the invasion of diseases and insect pests and inhibit the occurrence of too many fruiting bodies. Then cut the surface longitudinally with a poisoned kitchen knife and arrange it on the sunny border. The gap is filled with fine sand and then thickened with fine soil of 2~3cm. Finally, the water solution containing calcium superphosphate, potassium dihydrogen phosphate and white sugar was added in a ratio of 2 ∶ 0.2 ∶ 1 ∶ 100, and then was managed according to routine management. This method can increase the output by more than 80%.

Anti-acid corrosion measures of Pleurotus ostreatus culture material
The recent hot weather, rainy and humid, very easy to breed acid bacteria, a little careless will cause losses to the production of Pleurotus ostreatus. How to prevent the acid rot of Pleurotus ostreatus culture materials, we should pay attention to six words: fresh, sparse, increasing, wind, dark and falling. Fresh culture materials such as rice straw, corn straw and wheat straw should be fresh and mildew-free, and should be exposed to the hot sun for 3 days before use. Sparsely use smaller plastic bags with a diameter of less than 20 cm to cultivate Pleurotus ostreatus, and put only one layer when sending bacteria, do not overlap, which is beneficial to heat dissipation. When mixing culture materials, use lime

Measures for the treatment of green mold of Pleurotus ostreatus
Reduce the temperature and humidity of the mushroom room, increase ventilation, and cover the mold with plant ash to prevent the spread of mold spores. First spray fumigation with 3% Lysol solution or 3% formaldehyde solution, and then wash the mold with 1% potassium permanganate solution. After sprinkling potassium permanganate particles on the mold, spray water on the periphery of the mold. Wash the mold place with 9 parts of quicklime and 1 part of carbendazim mixed with proper amount of water. Soak the mold in 5% limewater, remove the limewater after the mold disappears, and add new materials. Inject it with 200 grams of carbendazim solution.
