Key Technical Points for Managing the Growth of Edible Mushroom Fruiting Bodies

First, open the bag mouths promptly and increase ventilation to meet the mushrooms' oxygen needs. The air humidity should be kept between 88-90%. At this stage, water should be sprayed lightly and frequently, and not directly onto the mushroom buds, so as to prevent the buds from being killed by waterlogging. After about 6 days, heavy and frequent spraying can begin. Generally, in summer, spray 3 times: at 8 a.m., 12 noon, and 4 p.m. In winter, spray 1-2 times depending on conditions. On cloudy, rainy, and windy days, water should still be sprayed, but the amount should be reduced. Before the fruiting bodies mature, the amount of water sprayed should be reduced. Scattered light is required. The temperature should be controlled between 12-18°C. Harvesting should begin when the edge of the mushroom cap flattens and starts to become wavy, and the area at the edge of the stem is sunken and has white erect hairlike structures. The interval between the first flush and the second flush is about 10 days. During the second flush, nutrient solution should be replenished promptly. The formula is 1 PPM naphthaleneacetic acid, 1 PPM triacontanol, half a jin of urea, 3 liang of monopotassium phosphate, mixed with 100 jin of water. After the third flush, the water in the bags is insufficient, so the method of building a mushroom wall and bed cultivation can be used for the production of the next flush. Generally, after about 5 flushes, move the spent mushroom bags out, spray the greenhouse with 3% carbendazim plus lime, and expose it to the sun for 2-3 days, and then the next batch of production can begin.
