As the economy develops, people slowly understand how to overcome the effects of adverse environments. In the mushroom cultivation technology, the cultivation technology of greenhouse is gradually introduced. The cultivation of mushrooms in greenhouses is convenient, the insulation of greenhouses is good, the autumn mushrooms are late, and a small amount of mushrooms can be produced in winter. The spring mushrooms are out early, and the high yield of mushrooms is easy to obtain. It can reach more than 9 kilograms, and the income of mu is about 10,000 yuan. If you master the cultivation technology of greenhouse mushrooms, then it will be a good way to get rich. Let's take a closer look at the following mushroom cultivation techniques in greenhouses.
Fermentation fermentation of greenhouse mushroom cultivation technology
1. Pre-outdoor fermentation: 2 days before the pile is built, the straw is cut into 2 sections, pre-wet, and watered while being overturned. The straw accumulation should not be too thick, and the middle and lower parts should be soaked. 3 to 4 days before the build, the materials in the formula (except lime and urea) are topped, the humidity is controlled at about 55%, and the pile is turned over in the middle. One day before the build, spray 0.5% dichlorvos on the mixture and cover for 12 to 24 hours. According to the routine, the stacking time is 5, 4, and 3 days. When the pile is turned over, urea and lime are added. The water content is between 65% and 70%, and the pH is 7.5 to 8.
2. Indoor post-fermentation: After the material is shaken loose, it is transported to the bed frame with a dump truck (the bottom layer is not placed), and is heated by a coal stove or a diesel drum steam furnace. When the temperature of the material rises to 60-62 ° C, keep 6 ~ 8 hours; proper ventilation, when the temperature of the material is reduced to 48 ~ 52 ° C for 4 to 5 days. After the end of fermentation, the material is dark brown, very soft, the straw is elastic, the hand is not sticky, there is no ammonia smell, there is a strong fragrance. There are a large number of actinomycetes, the water content is 65%, the pH is 7.2~ 7.5.
Overturning and sowing of mushroom cultivation techniques in greenhouse
When turning over the grid, you must pay attention to controlling the temperature. When the temperature of the material is lowered to 28 °C, the thickness of the material is 18-20 cm. The upper layer can be slightly thinner and the bed surface can be leveled. Spread with wheat seeds, use a bottle of 1 bottle / square meter, pat the seeds to make full contact with the material, cover the wet newspaper on both sides of the door, in order to master the mushroom cultivation technology in the greenhouse, then this link is very important .
Post-sowing management and covering of greenhouse mushroom cultivation techniques
After sowing, adjust the air and humidity in the shed to adapt to the growth of the mushroom. The basic cover of the mycelium for 7 to 10 days, after which the ventilation can be increased and the door can be opened day and night. Usually 20 days after the sowing, the mycelium is sent to the end.
The covering material is ç »ç³ mixed soil. Before 10 days of covering the soil, 3500-4000 kg of mud is prepared for each 111 square meters. The ratio of muddy mash is 1:24, dry sputum is 100-170 kg, and lime is 50 kg. The sorghum and lime are sprinkled on the open space in proportion, then broken with a medium-sized tractor. The granules are larger than the soybeans, sieved, and sterilized with formaldehyde after ridges. The thickness of the covering soil is 3.5 to 4 cm. After the coating is completed, the water is sprayed to the humidity to the saturated state. In order to master the greenhouse cultivation technique, the temperature in the shed and the thickness of the covering soil must be controlled to ensure the quality of the mushroom.
