First, the reason 1. The strains are too old and the amount of seed is too large. When the hyphae have not been fully grown or have long-term penetration of culture materials, a large number of young buds will appear. Since the hyphae in the culture materials have not yet reached a physiological maturity, they will not be available when they grow to young mushrooms. Nutrient supply shrinks and dies. 2, raw material too dense too much fruit, resulting in lack of nutritional groups, resulting in death of young mushrooms. The distinctive feature of this type of mushroom is the large amount of death of the young mushroom. 3. When harvesting a mature fruit body, the mushroom on the bed surface suffers from vibration and bumps and causes death. 4, pests and infections. The mushroom showed yellowish rot or brownish soft rot and finally dried up; when the humidity was high, it was water-stained and touched the dead mushroom. Check the culture materials, visible activities of mushroom fly, fleas and so on. Second, countermeasures 1, to avoid the use of strains of bacteria on the production of excessive age, when the species culture medium above the coral-like fruiting bodies or grow fruit bodies from the gap in the cap, indicating that the bacterial strain of the bacteria has a longer age, should limit the use. When the bottom of the bottle has a small amount of yellow water, it has no use value. The optimum amount of bacteria is 4% to 12% of the cultivation material, which is more when the raw material is cultivated, and less when the clinker is cultivated. Avoid blindly increasing the seed amount. 2, when the material surface appears too much dense mushroom, you can artificially remove part of the young mushroom to reduce nutrient consumption. Can also use animal compound humic acid sodium 400 times spray culture material, or with a long time (B9) 5 grams, 20 grams of magnesium sulfate, boric acid 5 grams, 10 grams of zinc sulfate, vitamin B1250 mg, urea 20 grams, 50 kg of water was formulated into a compound nutrient solution to provide nutrients to supplement the nutrients and promote rapid enlargement of fruit bodies. 3, when harvesting mature fruiting bodies, the action should be light, with a sharp knife cut along the root of the fruiting body, to avoid vibration, bruised mushrooms. 4, before the opening of the mushroom shed, it is necessary to do a good job in the field of pest control sterilization, extinguish mushroom fly, and other bacteria. According to every cubic meter of sulphur 10-12 grams, formaldehyde 8-10 milliliters, dichlorvos 1-2 milligrams, sealed stuffy fumigation for 24 hours, even smoked 2-3 times. The old mushroom room needs to be brushed with lime. This basically ensures that no heavier diseases occur in the entire cultivation cycle. In the event of fruiting insects such as mushrooms and other harmful insect pests, the bed planted with 3000 times the liquid directly injected into the material, each 50 kilograms of culture material injection of 2.5-5 kilograms of drugs, but note that the bed can not be long-term accumulation of water. For wall-type bags, use the mushroom net 3000 times liquid to pour into the bag and soak for 1 day. The next day, the excess liquid is poured out and can be processed twice in succession.
