Mushrooms are tender, crispy and delicious. In recent years, prices have been rising. The outlook is very promising. Moreover, the mushroom is a high-temperature mushroom species, which is also the fastest harvest among all edible fungi. It takes only 10 to 14 days from sowing to harvest, and it only takes about one month to grow a crop, which is very suitable for summer greenhouse cultivation.
The main raw materials for producing straw mushroom are wheat straw, corn and other straws, which can solve the problem of straw treatment and increase the environmental protection. After the straw mushroom is cultivated, the remaining waste is directly left in the soil as a fertilizer, which can increase the organic matter content in the soil, increase soil permeability, reduce soil pathogenic bacteria 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:
Raw material treatment Fresh wheat straw, corn, cottonseed hulls, etc. are selected as raw materials. Take wheat straw as an example, first soak it with 3%~5% lime water for 24 hours, then pick up and drain it, mix it with gypsum, livestock and poultry manure, phosphate fertilizer, and grass and wood ash to build a heap and ferment. 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 9 or so.
Sowing ridge sowing is a new method for high yield of straw mushroom. The sowing uses three-layer ridge cultivation, first spreads on the ground, is 30-40 cm wide, and is 10 cm thick. It broadcasts a layer of bacteria along the circumference and wheat bran uses 3 layers. % of the lime water was mixed and placed in a mushroom house for secondary fermentation. Spread a layer of 10 cm wide wheat bran in the center of the sowing plant. Spread the second layer of material, sowing, and wheat bran in accordance with the above method. Spread the top layer of material and apply a layer of bacteria to the surface of the seed and cover it.
After sowing, keep the temperature of the material at about 36°C and keep the film removed for 2 to 4 days. After sowing, the bed was covered with a thin layer (about 1 cm) of fertile sandy loam, and some 1% of lime water was sprayed on the soil layer to keep the soil moist and covered 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. 4 to 5 days after sowing, mushroom water should be sprayed once. After the water spray, ventilation should be properly conducted to avoid closing the doors and windows after spraying. Otherwise, the hyphae will be long. Under normal conditions, young mushroom formation begins 6 to 7 days after sowing. At this point should pay attention to insulation moisturizing, and appropriate ventilation and ventilation. Maintain the material temperature 33 °C ~ 35 °C, relative humidity of about 90%, to maintain 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.
