First, choose strains: Experiments show that the ideal strains are: low-temperature type 792,118 oyster mushroom, medium-temperature type Xinnong No. 1, 9400 oyster mushroom, oyster mushroom; high-temperature Hainan No. 2 and so on (the strain of Binhai County Institute of Edible Fungus can provide).
Second, the season according to row: along the middle and lower reaches of the Yangtze River along the river, from the beginning of August to the middle of February can be sown, of which the best sowing date from mid-September to mid-November.
Third, straw selection: Use foot dry, no mildew, golden color straw, and sorghum grass, early rice straw and rice straw next year as well.
(1) Lime-water soaking straw The straw is pressed and the straw tube is broken. Then, the straw is bundled and put into the soaking tank to press the heavy material. Soak 2% for 4 days with 3% lime water, turning the pool 1 or 2 times to make it soak. The length of time for soaking depends on the temperature at that time. After soaking, the PH value of rice material is between 8 and 9, and the water content can reach about 60%. After soaking, the straw can be further fermented and the temperature of the heap can reach 60 degrees or more.
IV. Quality of strains: Tests have shown that there is no need to add wheat bran, rice bran, and other organic materials in the rice cultivars and straws, which will greatly benefit the prevention and reduction of bacterial contamination. Cultivated species age, wheat grain 25 to 30 days, cottonseed shell species 20 to 25 days. Seeding rate: 20 to 25% for wheat seeds and 25 to 30% for cotton seed shells.
Fifth, the production of bacterial material: Pressing bacteria indoor bed frame cultivation, the bed frame is slightly tilted to facilitate the elimination of water within the material; after sowing, put the board on the film and pressurize the weight. For outdoor cultivation, the trampoline should not be deep, and the drainage conditions should be as good as about 15 cm; poor drainage conditions can be used as a ground-type trampoline, and the inner circle should be made 15 cm high. After sowing, the film was covered with a layer of rice straw and covered with 5 cm fine soil.
Six, nutritional supplements: Insufficient stamina of straw, late to add nutrition, in order to facilitate high yield. Specific methods: After harvesting a batch of mushrooms, they can be sprayed with mushrooms, strong and strong, and diammonium phosphate solution; or sprayed with 0.2% urea and 2% sucrose mixture, spraying 3 to 4 kg per 100 kg of hay. Spraying nutrient solution can increase production by 15 to 20%.
