Coprinus comatus has been widely cultivated throughout the country because of its rich nutrition, delicious taste, tender meat, and large market demand. It has been widely cultivated throughout the country and its development prospects are very broad. However, most mushroom farmers are often used in actual cultivation. A species of C. sinensis (commonly known as C. sinensis) is plagued by negligence and prevention, until the occurrence of large-scale infection, the use of some high-residual pesticides indiscriminate treatment, not only no effect, but also often lead to excessive pesticide residues in finished mushrooms, affecting Product sales. Here are some of the technical problems of Mushroom farmers. The answers are as follows:
1, specificity
The chicken claw fungus, belonging to ascomycetes, is highly specific to the infection of the pathogen and only found its harm to the coprinus comatus.
2. Incidence conditions
The high temperature and high humidity of the chicken claw fungus, which grows rapidly between 20-35°C, decreases when the temperature is lower than 20°C but still can cause harm. The initial staining conditions of the chicken claw fungus were mainly soil colonization. When the coprinus comatus was 2-3 times fresh, the chicken claw mushroom began to emerge. Wherever the chicken claws are grown, the mycelia of the coprinus comatus gradually subside, no more mushrooms, and even no harvest. This is enough to prove that it is a great harm.
3, prevention measures
1 Strictly dealing with soil-covered materials Because the pathogenicity of the chicken claw fungus is mainly formed through the sowing process of the soil-covering material and the base material, and because the coprinus comatus is not covered with soil, it is one of the main preventive measures to strictly treat the overburden material. . First, use deep soil below 30cm on the surface, and then kill the king 1:500 times with chicken claws and mix well, then boring for 24 hours. The probability of occurrence of the occurrence of C. sinensis in the cover soil on the site is too great to be promoted.
2 sowing the environment, strengthen the killing and mixing materials and bagging sowing sites, expand the scope of clean up 30 meters, the first match against the king claw killing 500 times the king to spray, and then carry out operations such as spices sowing.
3 During the management period, regulate the use of drugs to minimize the use of serious residual drugs of formaldehyde. During germination and mushrooming, the 500-fold solution of the chicken paw extract is sprayed every 5 days or so, and the area with severe disease can be changed to about 2-3 days and increase the dosage.
4 After finding the bacteria, strengthen the ventilation, stop the water spray and immediately expand the raw material by 5-10 cm. Completely remove the shed with the casing material, and incinerate or deeply bury it, or form a concave circle around the disease. Into the boiled water, the bacteria can be burnt to death. Finally, it was sprayed with a 500-fold solution of the king claw of the chicken claw. The effect was remarkable. For details of other precautions in the specific operation, please refer to the product manual of the Claw of the Crucify Claws.
