First, rice straw softening treatment of the epidermis has a layer of wax, this layer of wax can hinder mycelium eating. There are three ways to soften rice straw: First, lay the rice straw on a clean surface and repeatedly roll it with stone chips until the straw becomes soft. The second is to cut the straw into 2 to 3 cm long sections, soaked in 3% to 4% of the lime aqueous solution, 34 hours after the fish out, rinse off the residual liquid, adjust the water content. The third is to use a feed crusher, install a screen with a diameter of about 2 cm to smash, crushed into strips, thin, loose, soft.

Second, the mixture of culture materials Pleurotus ostreatus growth and development of a suitable carbon and nitrogen ratio of 20:1, based on this design culture material formula: straw 88%, 糠8%, plant ash 3%, gypsum powder 1%, urea 0.3%, moisture content 65%~70%. The softened and processed straw is added into the auxiliary materials and water according to the formula, and then the height and width are each about 1 meter. The length is determined by the construction of the site and the pile is fermented. The top and the bottom are slightly compacted and beaten, and the diameter is 3 cm. 20 to 30 cm from the top of the vertical hole, and then covered with film and straw moisturizing. When the temperature of the material rises above 55°C, maintain it for 8 to 10 hours, turn it over, and turn it over 3 times. When the accumulated temperature exceeds 55°C for more than 24 hours, the fermentation is completed. At this time, the pH value reaches 6-7, and the culture medium is light brown with aroma.

Third, when the crop is used for cultivation, the ground or paddy field near the water source is selected as the cultivation field. The venue will be 1.2 meters wide and the length will vary with the venue. During the excavation, first leave 30 centimeters wide soil in the middle of the raft. Dig the middle to 16 centimeters by 17 centimeters wide by 20 centimeters deep. Dig out the 45 centimeters wide and 10 centimeter deep pits on both sides of the raft. The mound is about 10 cm high around the concrete. After digging, the entire boring machine shall be sprinkled with 5%~10% lime water or 0.2% carbendazim solution. Then 0.02% dichlorvos solution shall be sprayed for thorough disinfection. And insecticide.

Fourth, when the material is sown and laid, it shall be filled with soil every 4 to 5 centimeters for every 60 centimeters, and about 12 kilograms of material shall be used per square meter. The use of wheat strains, with the amount of about 10% of dry materials, first 5 cm 5 cm distance sowing, and then broadcast a layer in the material surface, and finally pressed with a wooden board compaction, covering the film, covered with straw hair bacteria. When the temperature after inoculation is above 20°C, the germination should be checked on the third day. If the material temperature in the film exceeds 28°C, it can be ventilated and cooled in the evening. Do not remove the film and ventilate it frequently so as not to cause mold contamination.

Fifth, mushrooming management temperature around 25 °C, 20 days after sowing mycelium can be covered with material, 22 to 24 days can bud. When it is more than 60%, it can be placed in a film arch and sprinkled with straw to adjust light. The first tidal mushroom does not need replenishment, and it can be flooded into the ditch in case of particularly dry weather. After the first tidal mushroom is harvested, let the material air-dry for 2 days and then flood the floodwater to the immersed material surface. Drain the water for 1 to 2 hours. After 2 days, irrigate the water in the ditch. After the material is soaked in water, the film should be used to cover the surface of the material for budding, so that budding can occur 3~4 days in advance, and the buds are more orderly and dense. More than 60% of the buds can be removed from the material film and enter the routine management. Receive 3~4 tide mushrooms. The technology is also suitable for the cultivation of Pleurotus ostreatus in crop stalks such as dried cotton seed hulls and corn cobs, and the biological efficiency is generally about 200%.
