Pleurotus ostreatus block germination and early prevention

After the inoculation of Pleurotus ostreatus, the bacteria will not germinate or germinate, and the mycelium will turn yellow and wither. Therefore, precautions should be taken as soon as possible.

One of the main reasons is that the strains are ageing and their viability is weak; secondly, the inoculation is burned by the flame of the alcohol lamp or the inoculation tool; the third is the high temperature injury of strains that cause burns; the fourth is the improper handling of raw materials, there is no flat drying Harmful chemical toxins produced by various microorganisms are present in the culture medium; the fifth is not timely sterilized after bottling or bagging, and the culture material is sour or odorous, resulting in a large amount of antibacterial substances; Alkalinity of the medium is too high; seventh, there are more woody cedars in the raw materials, aromatic oil and other bacteriostatic substances are high in content; VIII, too much urea and other chemical fertilizers are added to the culture materials, so that the ammonia in the culture material is too heavy, inhibiting The germination of bacteria.

Precautionary measures Use of age-appropriate strains. Mycelial activity is more prosperous in 20-25 days. The high-temperature weather is vaccinated in the morning or at night. The culturing room enhances the ventilation and reduces the temperature or delays the cultivation time properly to avoid high-temperature injuries. Avoid scalding mycelium during inoculation. Appropriate increase in the amount of gypsum ingredients, bottling and bagging after sterilization. The amount of lime can not be too large, generally about 2%. Use raw materials that are dry and free of mildew, and raw materials mixed with cedar cedar should be naturally stacked for more than 6 months. After the sun and rain, aromatic oil antibacterial substances are removed. Add appropriate amount of chemical fertilizer according to the selected material, and the added amount of urea should not exceed 0.1%.
