Last Updated: 2024/11/22, The first and middle of August is the golden period of cultivating Pleurotus ostreatus in early autumn. using fermentation material to cultivate Pleurotus ostreatus is one of the important technical measures to improve the yield and benefit of Pleurotus ostreatus. However, many mushroom farmers failed because of the unscientific preparation of culture materials. The correct preparation method of Pleurotus ostreatus culture material is as follows: first, adopt a reasonable formula. Mushroom...

All aspects of Pleurotus ostreatus production may be contaminated by miscellaneous bacteria and must be prevented in time. The common miscellaneous bacteria are mainly as follows: 1. Most of the bacteria occur on the slope of the mother species, and the harm of the original species and cultivated species is relatively light. Bacterial contamination is characterized by rapid reproduction, which can be shown in 10 to 24 hours after inoculation. Prevention and control methods: first, vaccination tools must be wiped with alcohol and sterilized with flame. Second, the sterilization of culture medium should be carried out in accordance with the regulations. 2. Penicillium and Trichoderma damage are common in original and cultivated species. Soon after invasion, it germinated and grew into hyphae, covering the surface of the culture medium. Trichoderma occurs in the fruiting body formation stage. When these two kinds of miscellaneous bacteria appear, they should be dug up in time. 3. Alternaria is most likely to produce Alternaria and produce a large number of orange-red powdery spores in the summer high temperature season. Strains contaminated by Alternaria should be eliminated in time; bottles should be thoroughly cleaned and soaked in 0.05% potassium permanganate water, or steamed and sterilized before use.
