Clean up the material surface in time. The fruit body covers 1-1.5 cm in diameter and 14-15 cm in length. After harvesting, the residue of mushroom stems and small mushrooms on the material surface are promptly removed, and the old mycelium on the individual material surface is removed, as far as possible. Reduce mechanical damage and protect the original mushroom base.
Proper ventilation and cooling. In the mushrooming stage, in order to receive high-quality velvet mushroom with small cover, long handle, light color, and rich tenderness, it is generally covered with a layer of plastic film on the mushroom bag to ensure the required humidity for growth of the mushroom and create a high concentration of carbon dioxide. Micro-environment. However, high humidity and high carbon dioxide concentration are not conducive to renewing budding. It can be used to remove air and ventilation in the morning and evening so that it can form the original foundation as quickly as possible and accelerate the tide.
Gives weak scattered light. Flammulina velutipes can completely form mushroom primordium in dark environment, but the amount formed is far less than that formed under weak scattered light environment, so it is necessary to give a certain amount of scattered light at the time of vortexing, “three fractions positive and seven fractions yin†The environment can speed up the differentiation of mushroom primordium to form mushroom buds.
Reasonably regulate the temperature. The optimum temperature for forming the primordium of the mushroom is 13-15°C. If the temperature is high, you can increase the amount of water spray in the empty room, and fully ventilate and cool. It should be noted that when the temperature is high, the humidity can not be too large, otherwise it will make the mushroom legs black and the villi increase, thus causing diseases. If the temperature is low, you can spray hot water or warm the mushroom room to avoid delaying the formation of mushroom primordium due to excessive temperature difference and affecting the growth of mushroom buds, which is not conducive to turning tides.
The moisture content of the culture material should be suitable. The water content of the culture material must reach 65% to 70% to ensure its normal growth and smooth transition in the later period. If the culture material is dry, add more fresh water in the bag at one time, and pour out excess water after 2-4 hours. Add 50-100 ml to each bag.
U-turn mushrooms. After the second tidal mushroom is picked, it should be turned on the other end to produce mushrooms, which will increase the speed of tidal turnover, and the yield is equivalent to that of the first tidal mushroom. However, it should be noted that the mycelium that is not thoroughly translucent or has bacterial infections should not be turned into a mushroom.
Prevent from surrounding mushrooms. Bag-infested Mushrooms often appear surrounded by mushrooms, and there is no or little fruiting phenomenon in the middle. You can add 20% of mixed wood chips to the culture materials to prevent not only the surrounding mushrooms, but also the formation of mushroom primordia.
