Oyster mushrooms can be cultivated all year round, but those cultivated in high-temperature seasons are more profitable. Reasons: First, the temperature in summer is high, the planting technology is difficult, and pests and diseases are prone to occur, which often leads to cultivation failure. Second, the total area of ??oyster mushroom cultivation decreases in summer and the total output is small, resulting in a shortage of fresh oyster mushrooms in the market and rising prices. According to the cultivation practice of our Edible Fungi Research Center over the years, as long as we can grasp the technical requirements and adopt some necessary scientific management methods, we can still achieve high yield and efficiency in cultivating oyster mushrooms.

The key points of its cultivation and management techniques are now introduced as follows:

1. The cultivation site should be in a dark and humid place. While ensuring ventilation, the mushroom fruiting site should be in a cool (shade) area. ), places with significant moisturizing and cooling effects, such as land-based shade sheds, semi-underground sheds, air-raid shelters, basements, cave dwellings and caves, etc. When building a greenhouse, choose a place with trees around it and groundwater next to it, which can widen the day and night. The temperature difference is conducive to the growth of mycelium of Pleurotus ostreatus.

2. In principle, the selection of varieties is based on the temperature of the mushrooming site and other conditions. There are several types of strains: high-temperature, medium-temperature, low-temperature and wide-temperature. High-temperature strains should be selected for summer production, and the mycelium must be strong and have strong growth potential. On the contrary, strains that are prone to aging and cannot withstand high temperatures must not be used, otherwise the yield will be greatly reduced.

3. The size of the cultivation bag should be reduced. In order to make full use of the culture medium, increase the mushroom yield, and avoid the phenomenon of "burning" at high temperatures, the length of the cultivation bag is required to be reduced to 40~42cm and the diameter is 20~22cm. between.

4. Selection of cultivation raw materials In order to ensure breathability and avoid natural temperature increase in the material, the ideal raw material in summer should be cotton seed hulls (containing no or very little lint), fresh and mildew-free culture material; appropriately reduce the amount of ammonia fertilizer; appropriately increase the amount of gypsum.

5. Control the culture medium-water ratio. In order to control the growth of mold and the natural temperature increase in the cultivation bag material in summer, it is better for the culture medium to be drier, and the material-water ratio should not exceed 1:1.1.

6. When building piles for fermentation and clinker cultivation, mix materials on the cement floor as much as possible. When stacking and turning materials, the culture materials should not be compacted, and the pile should not be too wide or too high. , some ventilation holes should also be drilled on the material pile, and the surface of the material pile should be covered with as little or no plastic sheet as possible to avoid poor ventilation and cause anaerobic fermentation; in order to improve the success rate, clinker production should be used in high-temperature seasons, and normal pressure should be used to sterilize the material. Bacteria, inoculated at both ends. Spread the bacteria evenly as much as possible to cover the material surface.
