What are the key points of prevention and control of mushroom white rot?

Mushroom white rot is one of the common diseases in the process of mushroom cultivation, once the disease has a great impact on the yield of mushroom, it will form a lump in the epidermis of mushroom, and there are serious white mold. Next, let's take a look at the key points of the prevention and control of mushroom white rot.

1. Key points of control techniques of mushroom white rot.

The typical process of mushroom white rot is the growth of a brown tumor on the surface of the cap and stalk, and then gradually increases to the formation of a layer of white mold on the surface of the diseased mushroom. The seriously damaged mushrooms become deformed and turn into strangely shaped white clumps, and finally the diseased mushrooms begin to shrink and soften, and the diseased area will flow out brown with foul-smelling mucus.

1. Once diseased mushrooms are found to be removed in time, they should generally be dug out together with mycelium and deep culture materials, and the pit should be filled up with sterilized soil. Used tools should also be sterilized with formalin to prevent transmission to healthy mushrooms.

2. Reduce the temperature and humidity on the basis of not cooling the nursery room. Generally controlling the relative humidity of the air below 95% and the temperature below 17 ℃ can effectively prevent white rot.

3. Drug prevention and treatment, Bordeaux liquid can be used to spray covering soil, which can prevent white rot and reduce the infection rate. You can also spray carbendazim with water on the surface of the mushroom bed, but before the mushrooms grow.

4. If the development of the disease can not be controlled by the above methods, the covered soil can be replaced with aseptic soil.

II. Matters needing attention in mushroom planting

The main results are as follows: 1. Pressure bacteria water conservancy in the lateral growth of hyphae

When planting mushrooms, we should pay attention to observe the growth of Pleurotus ostreatus. After the hyphae begin to emerge, the mushroom should be ventilated and the air volume should be large enough to make the hyphae lodge by the wind. Also water, twice a day, to control the amount of water to keep half of the soil in the mushroom bed wet. Watering and ventilation are carried out at the same time, so that the 5mm thick soil on the mushroom bed is slightly dry, which is conducive to the lateral growth of hyphae, thus promoting the ripening of mushrooms.

2. Control the frequency and dosage of mushroom water.

The irrigation of mushroom water is generally about 3 days after pouring pressure bacteria water. The frequency and dosage should be controlled according to the humidity of culture material and soil water content. Generally watering 6 jin per square meter, divided into 4 times. Until the soil is completely drenched, pay attention to ventilation to prevent excessive humidity from causing rot.

3. The water temperature of mushroom is controlled.

The dosage, method and matters needing attention of mushroom water are basically similar to that of mushroom water. The key point is to control the water temperature is not lower than the soil temperature, as far as possible consistent, because the temperature difference is too large, the temperature difference will affect the growth of mushrooms. Spraying is the main watering method.

4. Maintain water to meet the growth needs of mushrooms.

Maintenance water must meet the needs of mushroom growth, usually at least once a day. At the same time, the times and dosage of watering should be adjusted according to the temperature and air quality of mushroom room. Keep the humidity around 90% and the soil moist. According to the growth of mushrooms, gradually increase the amount of water and frequency to provide sufficient for the growth of fruiting bodies.
