Straw mushroom is a kind of edible mushroom with unique flavor. The mushroom meat is delicate, crisp, and tasteful. It is favored by many consumers. The straw mushroom is native to the south of China. In recent years, it has been promoted in parts of our province and has achieved good results. When wheat is harvested once a year, the advantages of wheat straw resources are fully utilized. Cultivation of straw mushrooms during the high temperature period in summer not only can effectively turn wheat straw into treasure, but also can make up for the shortage of mushrooms on the summer market, and increase the economic benefits of growers. . 1. Preparation and processing of raw materials Wheat straw is a high-quality raw material for cultivation of straw mushrooms. After the wheat is harvested, the wheat stalks are piled up to prevent the rain from soaking. The wheat straw for cultivation of straw mushroom is preferably treated as a small section of 10 to 20 cm. If there is no condition treatment, the whole straw wheat straw thrown by the combine harvester can also be used. When raw materials are processed, about 5% quicklime powder, 2% gypsum, 0.1% carbendazim, 0.1% dichlorvos insecticide, and 150% clean water are added according to the dry weight of wheat straw. The wheat straw was soaked in a heap boring and fermented for 3 to 5 days, during which it was turned 3 times and the temperature inside the heap was kept above 65°C. It is advisable to adjust the moisture content of the wheat straw culture material to a small amount of water droplets by hand when it is sown. 2. Selection and Treatment of Cultivation Sites In many places, straw mushrooms can be cultivated. Ordinary houses, plastic greenhouses, fruit trees, and woods can make straw mushrooms grow normally. For management convenience, it is usually cultivated in rooms or plastic greenhouses. First, dig a narrow ditch in a greenhouse. The ditch is about 20 cm wide and 15 cm deep. The length is not limited. The lime powder was sprinkled in the ditch, water was poured, and 0.1% dichlorvos was sprayed on the insecticide. 3. Timely sowing science management According to the climate characteristics of our province, from the beginning of May to the beginning of October, the mushroom can grow. After the wheat straw is well-fermented, the wheat straw is filled into the treated narrow gutters, and the wheat straw is pressed and pressed flat by hand or board. A small amount of dry wheat bran is sprinkled on the top layer of wheat straw, and the amount is 3% to 5% of the dry weight of wheat straw. A layer of straw mushroom is then sprinkled in the upper layer. The amount of wheat bran used is 5% to 8% of the dry weight of wheat straw. After sowing, the bacteria and the material surface will be fully combined with a layer of newspaper or mulch film to keep the material surface moist. After sowing, keep the ambient temperature at 25 °C ~ 32 °C, ventilation 2 ~ 3 times a day, each time 30 ~ 50 minutes, when the material surface is dry, spray a small amount of clear lime water. Generally 7 to 10 days can be seen around the trampoline young mushroom appearance. 4. Regulating the Environment Timely Harvesting Mushrooms When the young mushroom grows, remove the cover of the trampoline and increase the ambient temperature inside the mushroom farm. According to the temperature changes in the water several times a day, the relative humidity of the environment is controlled between 85% to 90%. To enhance ventilation, straw mushrooms should be harvested in an egg-shaped shape without breaking the membrane. Due to the rapid growth of straw mushrooms, mushrooms should be harvested 1 to 3 times a day. After harvesting, fresh mushrooms will be sold or processed in time. Under normal circumstances, a species of straw mushroom can be harvested 2 to 3 mushroom.
