Auricularia auricula planting: how to prevent and cure auricularia auricula?

What harm does black fungus flow ear disease have? How to prevent and cure black fungus ear disease? There are no netizens to help introduce black fungus ear disease is planting black fungus process is very easy to infect a pest. Planting network sorted out the harm and prevention methods of black fungus ear disease, listed below for netizens reference. Black fungus ear disease hazards: Once Auricularia auricula is infected with ear disease, it will reduce production in mild cases and lose harvest in severe cases, which will seriously affect the economic benefits of mushroom farmers. When auricularia auricula disease occurs, the affected ear piece is pale yellow to brown in the early stage, sticky on the surface, with fishy smell, and the whole cluster of auricularia auricula decays in the late stage. From the view of pathogenic causes, ear bleeding is the result of comprehensive action of nematode, bacteria and protozoa, among which nematode is the main cause of ear bleeding. Prevention and treatment of black fungus ear disease: Measure 1. When the temperature in the shed is high, cool down in time: Hang wet curtains at windows, spray water to cool down, open doors and windows for ventilation at night, and control the temperature within 30℃ as much as possible. Under such temperature conditions, not only the auricularia auricula ears out quickly, ears out evenly, good opening, color is positive, but also the growth and reproduction of nematodes are inhibited to a certain extent. If the temperature exceeds 30℃, the nematode reproduction is accelerated and it is easy to produce ear flow. Measure 2. Drainage of black fungus planting site: The ear shed site should have a certain slope, and the top soil should be sandy soil for easy seepage. Measure 3. Use clean water in the production process: Clean and hygienic water sources, clean deep well water is the best source of water. Because bad water will carry germs, resulting in the incidence of agaric. Measures IV. Strengthen the management of temperature and humidity at all stages: Auricularia auricula has different requirements for temperature, humidity and ventilation at different growth stages. During the primordium formation period, keep the relative humidity at about 80%, and moderate ventilation. At the primordium differentiation stage, coralline ear buds are quite tender, and the relative humidity should not be too high at this time, and it should be kept at 80%-90%. In order to promote the ear rapid growth, ventilation should be increased and the relative humidity should be controlled at 90%-95% during the fruiting body growth stage. Harvesting begins when the ears of fruiting bodies fully expand, the edges become thinner, the ears contract and the fruiting bodies are eight minutes mature. Measures V, prevention and control methods: If a small amount of ear flow occurs, first remove the ear flow, then spray the fungus with 1%-2% salt water, and spray the ground with 5% lime water to control the further spread of nematodes and bacteria.
