What if Pleurotus ostreatus finds that the noodles are blackened?
The main causes and prevention methods of blackening of material surface are as follows:
(1) the hyphae of Pleurotus ostreatus soaked in water for a long time, causing rot and blackening. In this case, the condensed water on the material surface should be absorbed in time. If the bacterial bed is produced, the excess water at the bottom should also be sucked dry in time.
(2) blackening is caused by miscellaneous bacteria pollution and pest breeding, and the blackening must be treated or dug up in time to prevent spread.

Cultivation techniques of imitating Wild growth of Pleurotus ostreatus
In recent years, diseases occur frequently in the cultivation of Pleurotus ostreatus. This is mainly due to the fact that the whole production process is under the condition of protection from beginning to end, and the vitality and disease resistance of mycelium continue to decrease. Imitating wild cultivation technology can better solve this problem. First, the preparation of base materials and the sending of bacteria in bacterial bags are carried out in accordance with the routine. Second, standardize the code to build a bacterial wall. When the primordium is shown in individual bacterial bags, the bacterial wall can be built. The bacterial wall is generally 0.8 meters wide and 15 meters long; the gap at one end of the mushroom column is strictly and smoothed with mud, and the other gaps are filled with fertile soil and watered.

Prevention and Control of Rust spot in Pleurotus ostreatus
The ferruginous or dark brown spots on the cap and stalk of Pleurotus ostreatus are called Pleurotus ostreatus spot disease. This disease is a kind of bacterial disease which is easy to occur in the growth stage of Pleurotus ostreatus fruit body. The pathogen causing the disease is Pseudomonas aeruginosa, which is widely distributed in nature. In the early stage of the disease, the disease spot is only needle-like size, the color is also light, generally does not affect the commodity value. After the aggravation of the disease, the plaque increases rapidly, and the color deepens continuously, often in oval or fusiform shape, or connected to each other to form large irregular plaques, accompanied by yellowish yellow changes around the plaques.
