Pleurotus ostreatus must be said to have management techniques
First, the management of the period of development. Due to the influence of many factors, the speed of the bacteria often differs greatly from the actual time required. Therefore, it is necessary to adjust the speed of the bacteria by using the temperature (actually the temperature of the material). The method is: if the speed of the bacteria is too slow, the heating method can be used to accelerate the bacteria. Even if it is heated by electric furnace or coal stove, it can also be used to heat up the film after stacking. It should be noted that when moving the bag, gently handle it, prevent the deformation of the bag, and cause gaps between the material and the bag to cause invalid mushrooms; control the temperature of the material within 33 °C; often adjust the position of the bag in the pile to promote the bacteria Consistent. If the speed of the bacteria is too fast, the temperature is reduced by using a loose pile, window ventilation, heat dissipation, etc., to slow down the speed of the bacteria.
Second, the mushroom period management. Mushrooms are taken about 25 days before the mushroom picking. The method is as follows: 1. Open the mouth of the two ends of the bacteria bag and punch the hole with the 8th wire. 2. Dip the bag into the nutrient solution. The nutrient solution formula can be selected: urea 1 kg + sucrose 1 kg + potassium dihydrogen phosphate 0.5 kg + spray Shi Bao 10 ml + water 100 kg. After 5 to 6 hours, remove the stack and close the bag. 3, close the doors and windows to keep warm and moist, the ground water is wet, keep the indoor relative humidity of about 90%. Heating in an electric furnace or coal stove makes the indoor temperature reach about 15 °C. So after 7 to 10 days, the two ends of the bag are a large number of buds. When heating with a coal stove, the flue gas must be discharged to the outside.
Third, the management of the mushrooming period. After opening the bud, open the bag opening, open the door and window and hang the wet straw curtain on the door and window, which can not only pass the fresh humid air, but also avoid the strong wind blowing straight. At the same time, keep a small amount of water in the indoor floor, and spray the space and wall 2 to 3 times a day to maintain a relative humidity of about 90%.
Fourth, harvest. When the mushroom body 8 is mature, it can be harvested. After the end of the mining, stop spraying water, clean the surface, close the mouth of the bag, and keep the indoor dark to rejuvenate the hyphae. The future mushroom and management are the same as before. It can continuously produce 5-6 mushroom, the total bio-efficiency is more than 150%, and the yield is concentrated in 1~2 tide.
