Causes: 1. Bacterial species are too old, and the amount of seed used is too large. When the hyphae have not yet grown or long-pilled culture materials, a large number of buds appear. Because the hyphae in the culture material have not yet reached a physiological maturity, they grow into young mushrooms. Not to supply nutrients and shrink to death.
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.
Countermeasures: 1, the production of bacteria to avoid the use of bacteria that are too large, when the seed culture medium above the coral-like fruiting bodies or grow out of the gap in the cap body, indicating that the strain of bacteria has a longer age, should be limited 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 Pleurotus ostreatus cultivation shed, we must first do a good job site pest control sterilization, extinguish mushroom fly, and other bacteria. According to each m3 sulfur 10 ~ 12 grams, formaldehyde 8 ~ 10 ml, dichlorvos 1 ~ 2 mg, sealed stuffy fumigation for 24 hours, even smoked 2 to 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 and other harmful insect pests in the mushrooming period, the net 3000 times solution of the mushroom planted on the bed is directly injected into the material, and 2.5 to 5 kilograms of the chemical agent is injected per 50 kilograms of the culture material, but it is noted that the bed cannot accumulate water for a long time. 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.
