First, water management
There are three main aspects of water management: one is to nurse the humidity of the culture material, the other is to maintain the moisture content of the soil in the soil layer, and the third is to control the relative humidity of the air in the mushroom room. 1 The water content of the culture material is preferably about 60% . 1 to 2 days before covering the soil, it should be sprayed once or sprayed with “Jiansusu” nutrient solution once, which can not only wet the culture material, but also make the hyphae grow vigorously. 2 During the mushrooming period, the water should be sprayed frequently on the soil cover. The water spray before the mushroom is mainly used to moisten the mud. When the fruit body first appears in the large number of mushrooms, spray light water once a day. Water; after collecting a batch of mushrooms, spray a heavy water to make the coarse soil absorb water, then reduce the water spray, or stop the water for 1 to 2 days, until the fruiting body is unearthed. Repeat the above management method later. 3 During the period from seeding to mushroom harvesting, the indoor relative humidity should be maintained between 85% and 95% . To do a good job of ventilation and ventilation, the management should not allow the culture material to be wet, so as to be loose and breathable. Within 3 days after the sowing of the strain , the mushroom house is mainly moisturizing, and does not open the doors and windows. After 3 days, in order to accelerate the growth of mycelium, it is necessary to ventilate for 2 to 4 hours every day . After covering the soil, the ventilation should be enhanced. In the absence of wind and rainy days, most of the doors and windows can be opened; if the north wind blows, the northwest doors and windows should be closed; When a large number of fruit bodies are formed, wet straw curtains can be hung on the doors and windows, which can be both ventilated and moisturized.
Second, topdressing skills
In order to capture the harvest of the mushroom, the mushroom can be topdressed by the method of root dressing. 1 Spraying with 0.2% potassium dihydrogen phosphate and 0.2% yeast powder, which is beneficial to the growth of young mushrooms. 2 Use white sugar, glutamic acid, vitamin B1 tablets to prepare nutrient solution. After collecting the third batch of mushrooms, spray once every 3 to 5 days to make the mushrooms grow firm and white. 3 spray "sturdy". Spraying No. 1 Jiansu ( adding ammonium molybdate and other drugs ) before covering the soil can promote the growth of mycelium. After receiving the second mushroom, spraying No. 11 Jiansu ( adding appropriate amount of novel plant growth hormone ) can accelerate the growth of fruiting bodies and reduce the death of young mushrooms.
