Pleurotus ostreatus culture material inadvertently mixed with herbicide, how to do?
Growing Pleurotus ostreatus should not be mixed with herbicides. As for the adverse effects of herbicides on the mycelium growth of Pleurotus ostreatus, we have not done any experiments in this respect. I want to mix 50 grams of herbicide into 2000 jin culture material, the concentration is not small, even if it does not affect the growth of mycelium, at least in the Pleurotus ostreatus fruiting body accumulated herbicide residues, it is difficult to ensure the safety and health of its products. The solution is to rinse the culture material mixed with herbicide repeatedly (5-6 times), then drain part of the excess water, then add an appropriate amount of carbendazim (about 20% less than the original amount), stack fermentation, inoculation culture can use the original method.

Pleurotus ostreatus can significantly increase production by spraying cold boiled water.
Spraying with cold boiled water in different periods of Pleurotus ostreatus, the bioconversion rate can be increased by 33%, and the Pleurotus ostreatus sprayed with cold boiled water can change tide quickly, produce mushrooms neatly, and the mushroom meat is thick. After the mycelium of Pleurotus ostreatus is transparent, remove the film and spray cold boiled water on the mushroom bed and the surrounding walls, so that the air relative humidity reaches 80-85%; when a large number of coral primordia occur, with the gradual growth of the fruiting body, cool boiled water is sprayed 3-5 times a day to increase the air humidity to 95%. Spray should be sprayed with fine mist and should not be watered with heavy water, so as to avoid stagnant water causing dead mushrooms.

Adding salt to the culture material of Pleurotus ostreatus can increase the yield.
In the cultivation of Pleurotus ostreatus, carbendazim is effective in the prevention and control of miscellaneous bacteria pollution, but the residual pesticides in the mushroom body are harmful to human health and the cost is high. According to the experiment: when Pleurotus ostreatus is cultivated with raw material, 1.5 kg of salt is added to every 100 kg of dry culture material (dissolved in quantitative water in advance), which can prevent miscellaneous bacteria infection and produce mushrooms 5-7 days in advance. At the same time, because the salt is rich in sodium, calcium, magnesium and other metal ions needed for the growth of Pleurotus ostreatus, if 10% salt water is sprayed at the initial stage of fruiting body differentiation and after each tide mushroom harvest, the mushroom body will be free of pesticide residues and quality.
