The causes and control measures of "continuous cropping" of edible fungi, and notes on the introduction of edible fungi.

I. the reasons for the continuous cropping of edible fungi

The main results are as follows: 1. Due to the planting of edible fungi for years, the facilities are polluted.

2. When the mushroom shed is used, the disinfection and sterilization is not complete, especially when the edible fungus is planted in the ground, the soil is not thoroughly treated with bacteria, the facilities in the mushroom shed are carried by bacteria, and the air is carried by bacteria, which leads to serious diseases and insect pests during the continuous cropping of edible fungi.

3. The consciousness of prevention is not strong, the occurrence of diseases and insect pests of edible fungi planted in the previous year or two is relatively light, and the contaminated bacteria bags are not disposed and thrown everywhere in time, which creates conditions for the accumulation of pathogens. Due to lax management and incomplete disinfection during production, pests enter the shed with culture materials, resulting in the spread of the disease everywhere.

II. Prevention and control methods

1. Clean up the environment: dung piles, haystacks and rubbish around the mushroom shed should be cleaned thoroughly, and carbendazim fungicides should be sprayed for disinfection.

2. Disinfection in the shed: potassium permanganate or quicklime is sprayed or sprayed in the shed, and the wall, four sides, columns, vents and so on should also be sprayed for disinfection, leaving no dead corner.

3. after the mushroom is finished, remove the sunshade and greenhouse film, and use the strong light of the sun to kill the pathogens in the greenhouse for a long time.
