Prevention of water blotches on mushroom lid
Generally speaking, after spraying water, the doors and windows are not opened in time for ventilation, so that the humidity in the mushroom room is too high, and the water droplets accumulate on the surface of the lid, resulting in rust spots locally. Rust spots are similar to bacterial spots, but only on the surface.
Precautions: on time or when the weather is suitable, open the doors and windows for ventilation, bring in fresh air and evaporate the moisture on the surface of the mushroom body.

Cultivate high-temperature mushrooms to control the "three passes"
The cultivation of mushrooms in summer has higher economic benefits. In order to grow mushrooms well in summer, there must be "three hurdles" of variety, fermentation and pest control. The main results are as follows: (1) the suitable high temperature type strains are Xincheng 96, Su Mushroom 1 and so on. The optimum temperature of Xincheng 96 is 18-36 ℃, 25-33 ℃ in greenhouse and 20-36 ℃ (24-33 ℃) in greenhouse. It is the most heat-tolerant strain at present. It is suitable for sowing in May-June and mushroom in June-September. Its greatest advantage is mushroom picking.

Prevent thin-skinned early opening mushrooms
Because the temperature is cold and hot, the temperature changes greatly, and the temperature difference between day and night is up to 10 ℃ 15 min. Under the condition of excessive ventilation in the mushroom room, or the temperature is higher than 18 ℃ for a long time, the mycelium grows fast and the mushroom is too dense, which can easily lead to the thin-skinned Pleurotus ostreatus with slender stalk, thin cover and early umbrella opening. Preventive measures: scientific management. Proper ventilation and water spraying; when the weather changes suddenly, strengthen the management to keep the suitable temperature and humidity in the mushroom room; the humidity of mushroom production should be kept at 12 ℃ 16 min, and the over-dense buds should be removed properly.
