Effective measures to control the size of Pleurotus ostreatus
In recent years, the market demand for the quality of Pleurotus ostreatus continues to improve, large mushrooms are not popular, some mushroom farmers can not keep up with the market demand to produce certain specifications of commercial mushrooms, resulting in increased production but not income. The specification can be controlled by the following measures. Strain "2796", which is widely used by the replacement strain, is a large-grain variety, and its main advantages are wide adaptability, strong stress resistance, large size and high yield, but relatively few meet the requirements. Therefore, the small particle strain can be replaced when there is an order contract. When the overlying soil layer is thicker, the hyphae in the soil layer are dense, but it is not easy to knot. Once the knot appears bud, the surrounding hyphae will concentrate nutrition and water supply, which is bound to grow into a large head fruit body. Generally speaking, the thickness of the normal cover soil is 3cm to 5cm, and the thickness of the soil cover is 2cm. The hyphae are easy to knot and bud, and the competition for survival is formed when the buds appear, so it is not easy to produce large mushrooms. The suitable temperature for the growth of Pleurotus ostreatus is 15-20 ℃, and the appropriate increase of greenhouse temperature can effectively increase the number of buds, so that most of the fruiting bodies are in the middle and lower level.

Using waste of Pleurotus ostreatus and Pleurotus ostreatus as organic fertilizer
There are more than 80,000 mu of rice in Haidian District, Beijing. Except for some straw, most of them are burned, which not only pollutes the environment but also wastes resources. According to this situation, we studied 9 mushroom species and finally determined that straw rot fungus Pleurotus ostreatus was one of the ways to utilize rice straw. The key techniques of cultivation of Pleurotus ostreatus are as follows. One.

The strain selected by strain selection must go through the mushroom experiment before it can be used on a large scale. The appearance must have thick white, stout, uniform hyphae, no growth interruption, no miscellaneous bacteria infection, no insect pests. Before disinfecting and feeding the mushroom room, clean up the mushroom room and indoor items, and then disinfect it. Fumigation is commonly used for disinfection, per cubic meter.
