Pleurotus ostreatus has a bright future
On the morning of July 31, Hangzhou Academy of Agricultural Sciences, Municipal Bureau of Agriculture and Hangtou Town Government held an on-site exchange meeting on new varieties and technologies of rare edible fungi at Huangmugang vegetable base in Hangtou Town. Leaders and experts from Hangzhou Academy of Agricultural Sciences, Bureau of Agriculture, Bureau of Science and Technology, Science and Technology Association, as well as agricultural scientists and technicians from various counties and cities in Hangzhou, inspected the experimental greenhouse of rare edible mushrooms in the vegetable base. According to Zhou Zufa, director of Hangzhou Edible Mushroom Station, Jinfu mushroom is a kind of high-temperature mushroom, which can produce mushrooms at 28 ℃ to 35 ℃, and it is nutritious and tastes good, so it is a high-grade variety, which just fills the gap in the fresh mushroom market in summer and has a good prospect. The yield of Pleurotus ostreatus is high, the yield per mu is about 4000 kg, the benefit is very good. The success of the pilot project of Huangmugang vegetable base in Hangtou Town has accumulated experience for large-scale popularization and development next year.

The yield of "wavy" mushroom planting is high.
The wavy cultivation mode is to spread the culture material on the bed surface into a kind of undulating wave when spreading materials and sowing seeds. Compared with the plane cultivation bed, the mushroom production area of this cultivation model can be increased by more than 50%; it is better than the plane cultivation method in removing harmful gases in the material and regulating the material temperature; without increasing any investment, the yield per unit area can be increased by 30% and 40%. The implementation methods are ingredients in the early stage of production, fermentation, arrangement and disinfection of cultivation sites, and various management work in the later stage of cultivation.

Control of spot disease of Pleurotus ostreatus
