In the cultivation and management of Flammulina velutipes, the fruiting period should not be directly sprayed into the fruit bodies and the materials. Therefore, after harvesting the two tidal mushrooms, it is difficult to give up the management due to serious water shortage in the culture materials, resulting in a low yield, biological The conversion rate is generally only about 130%. In the years of production practice, the author observed that the growth and development of Flammulina velutipes has a close relationship with the water content in the material. The amount of water in the material is directly proportional to the increase and decrease in the level of output and quality. Therefore, changing the conventional management methods during the fruiting period and strengthening water and fertilizer management in a timely manner have achieved ideal results. The method is that when the mycelium reaches a physiological maturity, the bacterial bag is rapidly transferred from the bacterium growing room to the cultivation shelf in the greenhouse to open the bag and induce budding and mushrooming. Put the film on the mushroom bed and place the bag on the bag before entering the bag. Raise the bottom of the film by 2cm. Add 0.5cm deep water to the film. Cover the surface of the bag and cover it with black film to protect the light from the dark film. The humidity in the interior space can be stabilized at around 90% for a long time, which is favorable for adjusting the temperature and humidity between the bags and achieving the purpose of producing fresh and orderly mushrooms. After the first tidal mushroom picking, due to the large amount of water consumed in the material, it is necessary to add moisture to the material and topdressing the nutrient solution 0.2kg in time, which is beneficial to the second tidal mushroom more than the mushroom, a good mushroom. After the tidal mushroom picking, the culture material has obviously contracted, and the material has a certain gap with the bag wall. In the later stage, the mushroom is easily produced from the bottom of the bag and surrounding the mushroom, which affects the quality of the mushroom. In order to prevent this phenomenon from happening, you can fill the bag with big water once again and make up 0.3kg of water per bag to make the culture material absorb water and expand. The excess water will drown the bottom of the bag and the wall of the bag to make it lack oxygen and be discharged on the material surface. mushroom. After this treatment, three more tidal mushrooms can be produced. Using this method of management, not only the number of mushroom production increased from 2 to 3 tides of conventional management methods, but also the biological efficiency increased from 130% to 260%; 1 The bioconversion rate of tide 3 mushroom was basically stable at 200%. About 4 to 5 tide mushrooms can also reach 50% to 60%. Each 100kg raw material can produce about 260kg of fresh mushrooms, and the income is between 700 and 800 yuan. Moreover, the quality has been significantly improved, the fruiting and ordering are neat, the stipe is thick, the cover is small and glossy, and the process of no need to be bacillus is really needed. The purpose of realizing high quality, high yield, and high efficiency is truly achieved. If the long-term ventilation is poor, the humidity in the shed is too high, which can easily lead to the occurrence of mushroom, mushroom, and mushroom, and the mushroom is immersed in water, and the cap is yellow. In severe cases, even introduction of various diseases and pests occurs. The ventilation time is too long, the space humidity is low, and the mushroom scales will increase, affecting the appearance of the goods. Therefore, during the fruiting period, it is necessary to maintain sufficient hydrogen in the shed and provide unobstructed ventilation without changing the humidity. This is the fundamental point for improving the quality and yield of Coprinus comatus. Supplemental soil cover: With the uninterrupted harvesting of mushrooms, the bed cover covers a lot of mushrooms for picking. Therefore, after each tidal mushroom, the bed surface should be supplemented with fine soil particles to keep the covering layer flat. In addition, when there are a large number of dense mushrooms on the bed surface, it is also necessary to supplement the covering soil in time and thicken the covering layer of soil to facilitate the growth of large mushroom bodies.
