Secondary inoculation to take two inoculation measures, is conducive to straw mushroom production. The mycelial growth rate of straw mushroom is too fast, and it is extremely easy to age, resulting in a weakened viability, and it is not possible to effectively use the nutrients in the cultivation material to continue mushrooming. After the first tidal mushroom is harvested, it is loosened and wetted with lime water, and the pH of the culture material is adjusted to 8 to 9; then, the seed is spread on the material surface and covered with a thin layer of fermented culture material after sowing. . Can also be in the first ~ 2 tidal mushroom harvest, turn the block over, turn the bottom layer of culture material to the surface, spray 1% lime water, adjust the pH. Then two times inoculation on the material surface, the inoculum size is 2%~3%, generally can increase about 30%.
Adjust the acidity and alkalinity specific practice: spray 3% lime water to the culture material, not only to make up the water, but also to make the culture material be alkaline; also can spray 0.1% urea and wheat bran water to the culture material (100 kg water and 10 kg Wheat bran, boiled and filtered, 50 kg of filtrate plus 50 kg of clear water). The amount of urea is 0.1%~0.2%, and the amount should not be too much, otherwise it will be prone to produce comatus miscellaneous bacteria; or use dry manure and human urine. The dried cow dung was broken, 40% of human urine was added, and the mixture was evenly mixed. Before being used for one day, each time a mushroom was harvested and then applied on the material surface, if some chickens and duck dung were added, the effect would be better.
The implementation of soil covering straw mushroom can improve the moisturizing performance of culture materials and adaptability to temperature changes, so as to make the mushroom body hypertrophy, reduce dead mushroom, and increase the yield by more than 20%. The cover soil material can be used for vegetable garden soil (digging below 8~10 cm on the surface), and the thickness of the cover soil is generally 2 cm.
