2. The malformation is mainly manifested in the slender mushroom stems, developed and thick roots, the external appearance of corals like the sea, mainly due to lack of oxygen in the greenhouse or poor ventilation.
3. Actress type: Mushrooms produce a large number of mycelial air mycelium on the surface of the mycelia, which makes the mushroom grow in a state of leggy. This phenomenon is mainly caused by excessive humidity in the greenhouse, which affects the normal growth of the mushroom.
For these several different types, the following measures should be taken to prevent the occurrence of mushroom diseases. First of all, in the cultivation, do not take too much water and control the humidity in the shed. When the humidity is too high, it must be promptly released. In addition, we must pay attention to the purification and rejuvenation of the strain, and the sterilization and sterilization of the carrier.
In addition, some of the flat mushrooms are harmed by aphids (star spiders), which are mainly manifested in the damage of mycelia and fruiting bodies of flat mushrooms. Individual caps and pleats were also damaged, resulting in the appearance of many yellow concave spots on the surface of the flat mushroom, affecting the quality and appearance of the mushroom. In addition, in the production of Pleurotus ostreatus, the species fly hatches a large number of larvae (also known as quail) after spawning at the base of Pleurotus citrinopileatus, damaging various parts of the Pleurotus ostreatus.
Control methods: Whether it is red spider or seed fly, all can be sprayed with 1.8% chlorpheniramine 400 to 600 times solution or 4% chlorogenic vegetable emulsifiable concentrate 400 to 600 times solution.
What are the diseases and pests of mushrooms
1. The disease type is mainly brown spot, with white hairy hyphae on the surface of the fruit body and brown spots on it. Affected by the disease, the mushroom cap shrinks and the individual mushroom caps are chapped; Rust spots dominate, and rust-colored spots appear on the mushroom handles and mushroom covers. The main reason is that the humidity in the shed is too large and the ventilation is poor.
