The cultivation technique Formula of Pleurotus ostreatus, the latest cultivation technique of Pleurotus ostreatus

Do you know how to grow mushrooms with big balls? Do you want to grow it yourself? Here is a simple and high-yielding planting method for you. Let's take a look.

1. The preparation of culture material: 100% of rice straw, 10% of wheat bran or rice bran, 5% of corn meal, 2% of gypsum powder, 1% of calcium superphosphate, 2% of lime powder, 10% of vegetable garden fertile soil, 70% of water content, 75% of water content and a pH value of 6: 65.

Second, raw material treatment: straw must absorb enough water before building a pile. The water content reaches 70% to 75%. The standard is: take a small handful of representative grass to tighten, there is water dripping, but the water droplets are broken. The results showed that the water content was suitable, and then the batch fermentation was built. 2 days before fermentation, mix other excipients evenly. Drenched with 500 times carbendazim solution and covered with film for 2 days. When the auxiliary materials are added to the material pile layer by layer, the hay pile should be tight, turn the pile once after 3 days, and then the pile can be moved into the cultivation ground for sowing in 2-3 days.

Third, the cultivation mode: it is more suitable to use outdoor raw materials and set up a simple plastic shed for cultivation. Because of the low cost of outdoor raw material cultivation, it is easy to operate.

4. Cultivation season: in most areas of the middle and lower reaches of the Yangtze River, two seasons can be planted in a year, that is, one season from September to December and one from December to May. The cultivation period to the north of the Yellow River and in the high-altitude mountain area can be advanced and the termination period can be postponed appropriately.

Fifth, site arrangement and disinfection: make the border a little higher in the middle and lower on both sides, and the excavated topsoil can be stacked on one side to cover the soil. Drains should be opened all around. After the border is completed, 1% tea seed cake water can be poured on the border, and insect repellents can be sprayed to prevent earthworms and other insect pests.

Sixth, spread materials and sow seeds: 20 kg of hay per square meter and 2 kg of bacteria. Spread a layer of material, sow a layer of bacteria, each layer is about 12 cm thick, the material is trapezoidal, compacted in order to cover the soil. Then cover the material surface with a film and cover it with a straw curtain to shade the sun.

Seventh, germ period management: the material temperature should be controlled at 22: 28 ℃, the maximum should not exceed 32 ℃, the water content of culture material should be 70% 75%, and the air relative humidity should be 85% 90%.

8. Covering soil: 25-30 days after sowing, the mycelium between the hole and the hole has been connected, and the mycelium in the material is close to the long-penetrating culture material, and the soil can be covered on the material surface. To cover the soil, we should choose the loam with rich soil quality, rich humus, loose and good aggregate structure. The thickness of the cover is 3cm to 4cm.

Management of mushroom emergence period: after the mycelium is full of culture material and covered with soil, the mushroom can be produced in 15-20 days.
