Summer Cultivation Technique of High Temperature Pleurotus ostreatus

With the advent of summer, the temperature is gradually rising and the number of edible fungi in the market is decreasing day by day. At this time, the cultivation of high-temperature Pleurotus ostreatus on the market can obtain considerable economic benefits.

Variety selection. The main characteristic of high temperature type Pleurotus ostreatus is high temperature tolerance, and varieties that can withstand 36 ℃ high temperature can be selected. At present, the widely used high temperature varieties are 831, Shuangnai 3 and so on.

The way it is planted. Pleurotus ostreatus planted in summer is generally suitable for indoor cultivation, so it is easy to control humidity. The width of the bed is 80cm 100cm, the distance between layers is 60cm, it can have 6cm and 7layers, and the aisle is left between the beds. If you carry out outdoor cultivation, choose woodland without direct sunlight, or wetlands with shade. Make the land into a mushroom bed with a width of 100 cm to 150 cm, a depth of 20 cm and an unlimited length, leaving a small ridge of 5 cm to 10 cm in the middle, or opening a ditch 10 cm in width to irrigate to adjust the humidity of the mushroom bed.

Sow seeds with ingredients. The selection of materials for the cultivation of high-temperature Pleurotus ostreatus is similar to that of low-temperature Pleurotus ostreatus. Cotton husk, rice straw and sugar dregs can be selected according to the adaptability of varieties, but the selection of auxiliary materials is different. Due to the high temperature, easy to infect miscellaneous bacteria, culture materials are easy to acidify, so it is not suitable to add wheat bran, bean cake, rice bran, sugar and other raw materials. In order to prevent miscellaneous bacteria, 1% lime water, 1% carbendazim and so on can be added when proportioning. When cultivated with straw, the straw can be directly immersed in 2% lime water to soften for 48 hours and then rinsed, so that the pH value is reduced to 8 before use. When feeding high-temperature Pleurotus ostreatus, the water content should be on the high side (70%-75%), and the culture material should be 10-15 cm thick, either on demand, sowing or layered sowing, but the surface layer must increase the amount of seed used to make it cover as soon as possible to prevent the invasion of miscellaneous bacteria. After sowing, the culture material is slightly compacted, covered with newspaper and film to shade and moisturize, and the outdoor cultivation is also covered with straw.

Germ management. Mainly temperature control. Generally, the temperature should be controlled at 30 ℃ ~ 32 ℃. When the temperature exceeds, the indoor temperature can be cooled by strengthening ventilation, air spray or underground water spraying, and the outdoor water can be directly watered to grass grass and film to cool down. About a week later, the hyphae began to connect to the cover, at this time, the film can be opened for ventilation, once every 2-3 days, half an hour each time, so that the hyphae can be full after 15-20 days. At this time, strengthen ventilation, cooling, humidification, after 3-4 days of culture, you can enter the mushroom stage.

Harvest in time. Due to the high temperature, it only takes about 3 days from mushroom bud to maturity, so it should be harvested in time. The postharvest bacteria were cultured for 2 to 3 days and sprayed with heavy water to make them bud.
