What treatment should be done before the use of edible mushroom greenhouse, edible fungus diseases and insect pests control

After the completion of each cultivation season, disinfection and pest control must be carried out in the mushroom shed, because edible fungi grow in the open environment, there will be a variety of miscellaneous bacteria and insect pests, the small environment in the shed will naturally accumulate a variety of pests. Simple, safe and effective procedures and methods are as follows:

(1) uncover the shed and expose to the sun. This is the first step in the post-processing of the greenhouse. Uncovering the shed and exposure to the sun can, on the one hand, make the pests spread with the wind and reduce the population density, on the other hand, drying and ultraviolet rays can kill molds and other miscellaneous fungi that are mainly harmful to edible fungi, and can also make the eggs of some insects dry and die. Under conditional conditions, after the mushroom production (ear) is over, clean the shed immediately, clean it, and immediately open the shed to dry until the next crop is used.

(2) spray or smear with lime water. Lime is a strongly alkaline substance, which has a good killing and inhibitory effect on a variety of molds harmful to edible fungi, and it is a non-chemical synthetic substance and environmentally friendly. Serious disease can be sealed sulfur fumigation, the dosage is 50 g / m 2.

(3) replace the topsoil. In the greenhouse cultivated for several years, there will be more harmful organisms and harmful substances accumulation on the ground, which will affect the growth of edible fungi in the next crop, especially the species of semi-open cultivation of fermentation materials. Digging up the topsoil 10 to 15 centimeters deep and replacing the clean new soil has a significant effect on reducing the occurrence of diseases and insect pests in the next crop.

(4) killing insects. If there are serious diseases and insect pests in the greenhouse, the greenhouse should be sealed and killed before cleaning. The specific method can use 5% fipronil (fipronil) 1000 times liquid spray, every 100m 2 spray amount is 1  5x 2  0g, pay special attention to the gap, wall corner and other places of drug spraying, to ensure that there is no dead corner. After spraying, the waste can be transported out in airtight for 3 days, and the second disinfestation can be carried out if necessary.
