Covering sediment can cure mixed bacteria of Pleurotus ostreatus
Miscellaneous bacteria pollution often occurs in the process of Pleurotus ostreatus cultivation, especially in the high temperature season. Most of these miscellaneous bacteria are aerobic, resistant to high temperature and high humidity, and can be prevented by covering silt. the specific techniques are introduced as follows: 1. Control of miscellaneous bacteria of Pleurotus ostreatus planted in bed. When Pleurotus ostreatus is contaminated by miscellaneous bacteria in big bed cultivation, the cause of pollution should be found out first. The common causes are sudden high temperature, water inflow into the material, unclean surrounding environment, insect pests and so on. According to the specific situation, remove the pollution source, and then treat the contaminated Pleurotus ostreatus as follows: sporadic miscellaneous bacteria on the material surface, use thick lime.

Control of miscellaneous bacteria of Pleurotus ostreatus by covering charred mud ash
Bed cultivation of Pleurotus ostreatus when Pleurotus ostreatus is cultivated in bed, if miscellaneous bacteria occur sporadically on the material surface, the miscellaneous bacteria can be removed by smearing or covering the affected area with thick raw lime mortar; if a large number of miscellaneous bacteria are produced on the material surface, the contaminated part can be covered with coke mortar 2m / 3cm thick, the coverage should be larger than the pollution surface, and the miscellaneous bacteria can be removed by tapping a little tightly. If the material surface is seriously contaminated by miscellaneous bacteria, cover the whole material surface with coke ash and clap tightly, the hyphae can return to normal growth after a few days. Bag cultivation of Pleurotus ostreatus first picked out the bags contaminated by miscellaneous bacteria, and then compared the terrain.
