How to prevent premature opening umbrella mushroom mushroom cap
Flammulina velutipes caps open the umbrella when no commodity mushroom is formed, but the vegetative lid of the early umbilical is easy to fall off, forming a mushroom with a sterile lid, which affects the quality. The reason for the occurrence: 1 is related to the variety. Some strains with short growth periods often exhibit this phenomenon. Therefore, when selecting strains, such strains cannot be used. 2 too much ventilation. To control the concentration of carbon dioxide, reduce ventilation and oxygen supply. 3 Feeding in the culture is out of control. In some varieties with short growth periods, the hyphae are already broiled in the end, so that the nutrients needed by fruiting bodies cannot be supplied normally. Some cultures have insufficient moisture content and cause nutrient transport difficulties. The early opening of the umbrella, especially in the second tidal mushroom, is more serious because of the excessive consumption of nutrients in the bag material and the inability to meet the requirement for the mushroom to continue growing. 4 Excess light, too much light can increase the mushroom. Preventive measures: Choose a good variety, in the time of seed production, one-time increase the moisture content of culture materials, the proportion of accessories on the formula can not be less than 25%. In addition, in the tide period, such as the lack of moisture in the bag should be re-hydration, and in the replenishment when adding 0.5% of the urea solution to supplement the nutrients, regulate nutrient supply balance.
