Mushroom culture can not be over-ripe
When growing mushrooms, the cultures should be fermented and decomposed first. Some farmers believe that the higher the degree of fermentative maturity of culture materials, the better, but it is not. If the culturing material is decomposed excessively, most of the nutrients in the cultivating material will be consumed by the microorganisms, so that the grass stem in the cultivating material will lose its elasticity, resulting in poor ventilation of the cultivating material and being unfavorable to the growth of mushroom mycelium. In addition, excessive accumulation of culture materials will also breed a large number of pathogens and pests, causing the mushroom to grow. Semi-mature culture medium is suitable for cultivated mushrooms. Semi-mature culture medium has the following four characteristics: First, the color of grass and manure is changed from golden yellow or yellowish green to brown, but it is not black, and there is no fecal odor, acid Stinky or corrupt odor. The second is that the grass stems are soft, and there is a tensile strength and elasticity when hand-pulling, instead of being lightly pulled, that is, even if it is not mature, it cannot be seen as grass stems. Holding materials in hand can be pinched and loosened naturally after loosening. The third is that the temperature of the reactor can still be maintained above 50°C on the 5th day after the last turn, but it should not exceed 660. Fourth, the volume of the stockpile is reduced by 40% from the original, the weight is reduced by 30%, the moisture content is about 60%, and no water droplets appear between the fingers during hand-pinch.
