At present, the management of Pleurotus ostreatus should pay special attention to cooling.
Pleurotus ostreatus is mainly produced in winter, and at present, most of them have entered the second or third stubble stage. at this time, attention should be paid to the cooling of Pleurotus ostreatus: first, the natural temperature in spring is suitable for the growth of Pleurotus ostreatus, and people are easy to ignore the control of the temperature in the greenhouse and bag; second, the decline of mycelium vitality, high temperature will aggravate the speed of mycelium aging. The third is that Pleurotus ostreatus produces mushrooms quickly and neatly in spring, and the respiratory heat produced will make the temperature of the bag rise sharply in a short time; fourth, to prevent the occurrence of yellow mushroom disease, yellow mushroom disease is easy to occur above 20 ℃. According to our investigation, yellow mushroom disease has appeared recently, and yellow mushroom disease is a destructive disease, which should be paid attention to. At present, the key point of Pleurotus ostreatus management is to make use of the existing facilities to reduce the temperature of mushroom shed and bag as low as possible, so as to maintain and restore the vitality of mycelium. Here are several cooling methods.
1. Stop all measures that may raise the temperature of the shed, such as leaving about 1.5 meters of light on the front roof to avoid long legs of Pleurotus ostreatus on a sunny day.
2. Under the condition of keeping the humidity in the shed, the ventilation volume should be increased as much as possible, and the bottom wind and upwind should be opened at the same time.
3. When the temperature of the shed reaches 18 ℃ during the day, all the grass grass should be pushed up at night, and the grass should be covered by day and night.
4. make use of low temperature weather such as cloudy and rainy days to cool down in time. On cloudy and rainy days, all the grasses are opened, and the vents are opened to the maximum, until the sunny day comes. Do not stop these measures even if the temperature of the shed is as low as possible.
The above measures should be comprehensively utilized to effectively lower the temperature of mushroom sheds and bacteria bags, and do not rush for success, so as not to cause unnecessary losses.

Interplanting Pleurotus ostreatus in rice field
During the growth and development of rice, interplanting Pleurotus ostreatus under the special conditions of rice row space and shade can not only provide suitable temperature and humidity conditions for the growth and development of Pleurotus ostreatus (large temperature difference between day and night, good shading, sufficient scattered light, etc.), and make Pleurotus ostreatus obtain high yield. it can also fill the market off-season with few mushrooms in summer, enrich summer vegetable varieties and increase the income of rice farmers. 1. Stubble arrangement and field design: Rice varieties should choose varieties with strong lodging resistance, plant height, culm diameter and resistance to rice planthopper. The sowing time is in late May and transplanting in late June, and the density is only

1 symptoms of soft rot 1.1 the surface of the culture material or mushroom body is covered with a layer of white woolly fungus, slender but growing fast, and the gradually infected mushroom body spreads light brown morbid from the base of the fungus, and the mushroom body gradually soft rot; about a week after infection, the mushroom body loses automatically or falls down with a gentle touch, just like Chinese cabbage with soft rot, but the soft rot mushroom body has no smell. The growth rate of the mushroom body which is not yet soft rot is very slow, and the bacterial cap is gradually yellowish, lifeless and not bright, which is obviously different from the normal mushroom body; the infected material is no longer infected.
