At present, Flammulina velutipes is in a period of mushrooming, and there are often irrational phenomena such as long, short and curved mushrooms on the production. How do we ensure that the mushroom grows neatly? After the budding, the mushroom enters the mushrooming period, and the fruit body of the mushroom on the medium begins to grow. However, because the development of the fruiting body has successive strengths and weaknesses, the growth is different. In order to make the mushroom growth consistent and improve the yield and quality of the mushroom, the mushroom farmer should control the development of the robust fruit body through the regulation of the greenhouse environment, so that the slower development of the fruit body to accelerate growth, to achieve a neat and consistent purpose. First, lower the temperature inside the booth. Reducing the temperature in the greenhouse to 4°C-6°C can inhibit the growth rate of the mushroom, so that the growth of the mushroom is consistent. Second, increase the ventilation time to meet the oxygen demand of mushroom. When the mushroom shed is not ventilated in the daytime, the film covered on the bacterium bag should be opened for ventilation. When the mushroom shed is ventilated and cooled in the evening, the mushroom farmer should cover the bacterium bag. When the temperature in the shed reaches 4°C-6°C, the shed of the mushroom shed can be closed. In general, the mushroom should cover the film for 12-14 hours in one day, and open the film on the mushroom bag for 10-12 hours. Again, try to keep the mushroom green in a dark environment. Because the light of 1-2 lux can already meet the needs of the growth of the mushroom, if the light is too strong, the base color of the stipe will be deepened and the cap of the mushroom will become larger, which will affect the commodity of the mushroom. In addition, the mushroom has a strong light to the light, the culture bag should not be generally moved after being placed, and the working light source should be fixed as much as possible, otherwise the mushroom handle will be distorted. Finally, the relative air humidity in the shed was maintained at 80%-85%. If the humidity is higher than 92%, it will cause the mushroom cover to be water-stained and even induce soft rot and brown spot disease. During the specific operation, water can be sprayed to the ground and space at the beginning of the mushrooming period. Afterwards, appropriate amount of mist-like water can be sprayed to the mushroom body according to the situation. After 3-4 days, the suppression of the mushroom can be released and the normal growth of the mushroom can be promoted. When the needle mushroom enters the normal growth stage, the temperature inside the mushroom shed should be maintained at 8°C-12°C, the relative humidity of the air in the shed is maintained at 80%-85% during the early growth period, and the relative air humidity remains at 80% during the late growth period. Can be about. At the same time, in order to meet the oxygen demand of mushroom growth, we must pay attention to increase the ventilation time of the mushroom bag to more than 12 hours. If the mushroom cap is found to be too large, the mushroom farmer should shorten the ventilation time, strengthen the shade, and weaken the light. When the mushroom grows to 15-18 cm in length, it can be harvested.
