Cultivation of stockpile system Cottonseed hulls as the main raw material for the cultivation of straw mushrooms must be selected without mildew, no pests and diseases, without fresh rain husked cottonseed hulls, drying before use 2 to 3 days. During the seasoning, a small amount of supplementary materials with high nitrogen content, such as manure and urine, urea, etc., must be sufficiently fermented during the composting process to kill pests and bacteria in the culture materials.
Raise the pH of the culture medium. The straw mushroom prefers a more alkaline environment. A pH of 7-8 is appropriate. During the cultivation, the pH can be adjusted by adding lime, and the added amount is generally about 5% of the dry weight, so that the pH value reaches 10 to 12. When the fruit body is formed, the pH value just falls into the range suitable for the growth of the straw mushroom.
Miscellaneous bacteria control common miscellaneous fungus umbrellas and molds, including mold, including Trichoderma, Penicillium, Mucor, Aspergillus, and so on. Preventive measures: Select fresh raw materials, control the nitrogen content and moisture content of the culture materials, and fully decompose the fermentation, and select highly active and non-polluting strains. If bacterial contamination occurs during the cultivation process, remove the pollution source first, then spill 5% lime water in the contaminated area.
Pest control Grass mushroom cultivation is usually harmful to pests such as cockroaches, mushrooms, and mosquitoes. Should be based on prevention, mainly to do a good job site disinfection before planting, with dichlorvos spray pile lid plastic film stuffy heap. If locusts are found to be harmed after sowing, special sprays of acetylene can be sprayed before fruiting.
