From June to October, it is the free time of vegetable plastic greenhouses in the northern region. The cultivation of Ganoderma lucidum on the soil inside can not only increase the economic benefits per unit area, but also meet the requirements of Ganoderma lucidum on ecological conditions. The biological efficiency can reach 90% to 120%, and the yield can be increased by more than 60% compared to the conventional bag planting method. Ganoderma lucidum is in normal shape, the diameter of the cover is 15-20 cm, and the color is beautiful. The qualified rate of export is more than 90%. Medium 1 cotton seed shell 88%, bran 10%, gypsum powder 1%, sugar 1%. 2 Wood chips 38%, cotton seed shell 50%, bran 10%, gypsum powder 1%, sugar 1%. 3 corn cob (corn kernel size) 50%, wood chips 29%, bran 20%, gypsum powder 1%. Sterilization is done in bags of 14 cm, 3 cm, .06 cm, or 15 cm, 0 cm, .06 cm in low-pressure polyethylene or high-pressure polypropylene bags. According to the proportion of raw materials, add water, mix and simmer for half an hour after mixing and stirring to keep the moisture content at 60% to 65%. Never avoid too much or too little humidity of the culture material. When there is too much moisture, the growth of mycelium is often inhibited due to lack of oxygen; when the water content is too low, mycelia grow weakly and it is difficult to form fruit bodies. The bagging and elasticity should be moderate. Each bag contains 500 grams of dry material. The filled bags are sterilized by atmospheric pressure. Inoculation is required when the temperature of inoculated germination bag falls below 30°C. Because Ganoderma lucidum is cultivated using clinker, the inoculation workload is large, and inoculation is generally performed in the inoculation room. After inoculation, the bacteria bag was placed on the culture rack and bacteria were found. The culture rack was previously sterilized with 0.2% carbendazim and a lime powder was sprinkled on the surface of the culture room to reduce pollution. Temperature control at 24 °C ~ 28 °C, air humidity to 60% ~ 65% is appropriate, dark culture for about 30 days, mycelium can be covered with bacteria bags. Site Preparation In order to create a good ecological environment for Ganoderma lucidum growth, Ganoderma lucidum fungus bags with good bacteria can be transplanted into plastic greenhouses for cultivation. Covering the grasshopper above, Ganoderma lucidum can not only direct sunlight, but also to meet its temperature, humidity, light and air requirements. Before the bag is put into the shed, the cultivation site must be treated first. Specific approach: 1 do a ditch. Dig 100-120 centimeters wide and 30 centimeters deep in the north-south direction. The length is determined by the shed. The distance between the two temples is 40 cm. 2 Sterilization. Spray 0.2% of carbendazim solution on the ground and the shed wall, and sprinkle a layer of grass ash on the bottom of the larvae for strict disinfection. 3 build arches. Ganoderma lucidum fruiting body optimum temperature for the growth of 27 °C ~ 29 °C, winter or early spring into the shed of the bag, in order to prevent the occurrence of malformation due to low temperature or large temperature difference between day and night, generally should be set up in a small greenhouse plastic shed. You can insert two ends of a good piece of bamboo into the soil, form an arch in the middle, cover the plastic film, and try to make the temperature in the shed reach 25°C or more. After the soil is covered with chiles, the bacteria bags with good mycelia are transferred into a plastic greenhouse. The surface of the bags is disinfected with 1% potassium permanganate solution. Then, the bag is cut with a blade, the film is peeled off, and the film is erected in the basket. It is 2 to 3 cm and filled with sandy loam. After the entire beak is full, about 1 cm thick ash is sprinkled on the top of the bacterium bag, and about 2 cm thick sandy loam is covered in the ash. After covering the earth, water is added to the earthworms. Generally, 500 grams of compound fertilizer is added to 50 kilograms of water. This not only moisturizes, but also promotes the formation of fruit bodies by the kink. The management of the bag after the cover soil is mainly moisturizing and ventilating, and should be protected from direct sunlight. During the period of June to October in the vegetable plastic greenhouse, all the plastic film around it should be lifted, and the roof should be shaded with grasshoppers. Generally, the mycelium of 7-10 days can be kinked to form the primordium. Two weeks later, the primordium began to grow on the ground, and the primordium differentiated to form a stipe in about 20 days. At this time, according to the density of the kiwifruit, some stalks may be properly removed to prevent the mushroom caps from squeezing and affecting each other when they grow up. After half a month of growth, the stipe grows and grows gradually. The color gradually changes from white to light yellow, and then deepens into yellow-brown. In the meantime, the air humidity should be maintained at 85% to 95%, scattering light should be given, and the temperature in the booth should be increased to 29°C to 30°C. Harvesting takes about 20 days from the formation of the cap to the harvest. When the color of the edge of the cap changes from white to red, the brown spore powder is faintly visible on the back of the cap, indicating that Ganoderma is mature and can be harvested. The first wave of water after harvesting for seven days will stop the growth of hyphae and promote the formation of new buds. After two months, the second tide may be harvested. Ganoderma lucidum after harvesting should be dried or dried in time, cut according to acquisition criteria, and sold in plastic bags. The handle of Ganoderma lucidum cultivated in the plastic greenhouse is short and thick, with deep color and large cap, which is very similar to wild Ganoderma lucidum and has high commodity value.
