Mushrooms are tender, delicious, and have a high nutritional value. In recent years, straw mushroom prices have been rising all the way, and the outlook is very promising. Moreover, the mushroom is a high-temperature mushroom species, which is also the fastest harvesting of all edible fungi. It takes only 10-14 days from sowing to harvest, and it only takes about one month to plant a crop, which is very suitable for the summer empty-shed period. Cultivation.
The main raw materials for producing straw mushroom are wheat straw, corn and other straws, which can solve the problem of straw processing. The cost is low, the source of raw materials is extensive, the technology is easy to grasp, and the efficiency is quick. After cultivation of straw mushroom, the remaining waste is directly used as fertilizer to turn over the soil, which can increase the content of organic matter in the soil, increase soil permeability, reduce soil pathogens and toxic and harmful substances, and is conducive to the normal production of sorghum vegetables. However, there is a point that when straw mushroom is cultivated, the shed is always in a high temperature and high humidity environment, and the damage to the materials used to construct the shed, such as bamboo rafts, steel racks and grass rafts, is large. Therefore, straw mushrooms are rarely cultivated in new greenhouses, but they are most suitable for cultivation in some old greenhouses where planting time is longer. They are not afraid of damaging the facilities such as brackets in greenhouses, but they can also improve the soil and increase the yield. The effect is obvious.
Cultivation of straw mushrooms can follow the following steps:
1. Raw material processing Select fresh wheat straw, corn, cottonseed hulls, etc. as raw materials. Take wheat straw as an example here, first use 3%-5% lime water to soak for 24 hours, pick up and drain, mix in gypsum, livestock and poultry manure, phosphate fertilizer, and grass and wood ash to build a heap fermentation. When wheat stalk composting and fermentation, generally the pile width is 1.2 meters, the stack height is 1 meter, and the length is more than 1 meter. The vent holes should be properly worn in the pile. After stacking, cover film moisturize. The prepared culture material should have a soft texture, a moisture content of 70%, and a pH value of about 9.
2. Seeding ridge sowing is a new method for high yield of straw mushroom. The sowing uses three-layer cultivation. First spread the material on the ground, width 30-40 cm, thickness 10 cm, broadcast a layer of bacteria around. Wheat bran was wetted with 3% lime and placed in a mushroom house for secondary fermentation. Spread a layer of wheat bran with a layer of 10 cm wide at the sowing center and pave the second layer of culture material, sowing, and wheat bran as described above. Spread a layer of culture material on top and spread a layer of bacteria on the surface of the material, and cover the membrane.
3. After the management sowing, maintain the temperature of the culture material at about 36°C, and keep the film removed for 2-4 days. Then cover the bed with a thin layer (about 1 cm) of fertile sandy loam, and spray 1% of lime water on the soil layer to keep the soil moist and cover it with plastic film. After covering the soil, the room temperature is controlled at about 30°C and the material temperature is maintained at 35°C. In the case of guaranteed material temperature, proper ventilation. The first 4-5 days to spray mushroom water once, after the water spray should be appropriate ventilation, to avoid immediately close the vent after spraying, otherwise the mycelium will be long. Under normal conditions, mushroom formation begins 6-7 days after sowing. At this point should pay attention to insulation moisturizing, and appropriate ventilation and ventilation. The temperature of the culture material was maintained at 33-35°C, and the air relative humidity was about 90%, maintaining a certain amount of scattered light. Do not spray the mushrooms directly with water. If the humidity is not high enough, use a spray of water at about 30°C. About 10 days after sowing, mushrooms are harvested.
