Planting techniques of Pleurotus ostreatus

The cultivation of Pleurotus ostreatus needs to prepare raw materials, such as rice straw, cottonseed hull, cow dung, phosphate fertilizer, wheat bran, water and so on. Then match according to the proportion, carry on the secondary fermentation, put all the culture materials into the mushroom room to sow seeds. During the growth period of Pleurotus ostreatus, temperature management needs to be strengthened, and the work after mushroom production can not be ignored.

Planting techniques of Pleurotus ostreatus

1. The stacking of culture materials. ⑴ cultivation raw materials. Formula 1: 42% of rice straw, 42% of cottonseed hull, 7% of cow dung, 6% of wheat bran, 1% of phosphate fertilizer, 1% of calcium carbonate, 1% of potassium dihydrogen phosphate, plus 70% of the total water of raw materials. Formula 2: 375 kg of rice straw, 10 kg of rice bran, 15 kg of chicken dung, 8 kg of calcium carbonate and 700-800 kg of water. ⑵ stacking. Usually pile up materials about 20 days before sowing Agaricus blazei Murrill. Generally, the pile is turned over for the first time on the 4th day after the heap, and phosphate fertilizer is added at the same time.

2. Secondary fermentation. Adjust the water content of the culture material to about 70%, transport it to the mushroom room or shed, put it on the shelf or make the bed, and the thickness of the culture material is about 20 cm.

3. Sow seeds. After the second fermentation, when the temperature of the material dropped below 25 ℃, the strain was broken into egg size, and the inoculation hole was dug about 10 cm deep in the culture material, and one inoculation hole was dug every 20 cm. Inoculation volume according to 3.3 square meters with 750 ml volume of bacteria 3 bottles, the amount of inoculation is about 6% of the dry material, and finally spread a layer of bacteria on the material surface.

4. Cover the soil. 15-10 days after sowing, when the mycelium spreads and grows 3-5 cm around the inoculation hole, it is covered with paddy soil. When covering the soil, adjust the soil to semi-dry and semi-wet, there is no white heart in the middle, the pH value is 7.0-8.0, about alkaline, and then spray fine water on the culture material surface, and then cover the soil with a thickness of about 3.3-3.5 cm.

5. Management before mushroom production. The temperature is controlled at 20-27 ℃, the humidity is kept at about 75%, and the material surface is kept moist.

6. Mushroom production management. Heat preservation should be strengthened about 20 days after inoculation, the temperature is 18-21 ℃, and the humidity is increased, so that the moisture content of the soil layer is 55%, 65%, and the air relative humidity is 85%, 95%, but do not spray water directly to the bed, so as not to cause dead mushrooms and rotten mushrooms.
