Mushroom cover soil, is to obtain the main measures of mushroom production. However, mushrooms fruiting or mushrooms in the first crop after harvest, the surface often occur mycoplasma surging long phenomenon, diffuse open to form a layer of impermeable, airtight bacteria, leading to delays in fruiting. This film consumes a lot of nutrients, resulting in reduced production, production must be prevented. First, the causes of bacterial film First, bagging mushrooms, bags
