The genus Deuteromycoides is a subgenus of the genus Armyceps. It is named because its seed entity resembles "chicken claw". The prevention of the development of the chicken claw fungus must start from the cut-off transmission route for comprehensive prevention and control. The key is to make good the following: First, do a good job in environmental purification, reduce the number of bacteria, culture materials preparation 1. Use high quality raw materials. The raw materials used must be fresh, dry and free of mildew. 2. Reasonable culture formula. 1 18% cotton seed shell, 28% corn cob, 35% edible fungus waste, 10% bran, 3% cake fat, 1.5% gypsum powder, 1.3% compound fertilizer, 0.2% fungicide, 3% quicklime, and 60% water -65%. 2 96% cotton shells, 1% gypsum powder, 3% lime, 60% - 65% water. 3 corn cob 38%, 35% cotton seed shell; 10% bran, corn flour 10%, sugar 1%, fertile soil 1%, quicklime 3%, water 60% - 65%. 3. The culture medium is first sterilized by fermentation after fermentation. The mark of fermented ripening is “the culture material turns brown, there is a large number of actinomycetes breeding inside, there is a material fragrance, the pH value is 7.5--8. Atmospheric sterilization method is: When the temperature rises to 100°C, it is kept for 8 hours-- 10 hours III.Cultivation methods and precautions 1.Cultivation method.The best method of cultivation is to use the bag planting method, which can effectively prevent the large area of ​​the chicken feet from infecting or spores to spread.The infected bags should be promptly removed. A small shed can be set to prevent bacteria contamination and moisturize, while accumulating a certain concentration of carbon dioxide, and relatively inhibiting the growth of chicken claw fungus 2. Environmental disinfection, 5% formaldehyde spray or permanganate in the shed and trampoline Potassium and formaldehyde mixture fumigated for 1 day - 2 days after fumigation 3. Doing a good job of earthwork treatment 1 Selection of soil cover Try to use fertile soil that has not been infested or left far away from the place where the disease occurred. The cover soil is first exposed to sunlight for 2 days - 3 days, and then 2% quick lime is used for mixing and sterilizing to adjust the pH. Each cubic meter of soil is coated with 5% formaldehyde 2.5 kg and mixed with 50% dichlorvos 200 times spray , and then sealed with a film for 1 day - 2 days, spread out After drying, water should be used to clean water, water should be cleaned, replenishment of water should be ensured when the water is replenished, and the water is clean and free from pollution, and it can be sprayed with 2% lime water 5. The ventilation should be stable 6. The cultivation season should avoid high temperature. High temperatures above 25 ° C. Cultivation season should generally be avoided in the late spring and early summer or in the summer and autumn high temperature season.Generally selected to plant in September - October is good. 7.Control insects.Insects are important In order to install insect screens, mushroom windows, vents, and vents are to be installed, and regular use of 50% dichlorvos 200 times solution to spray around the mushroom house or installing a black light near the mushroom house.
