Brazilian mushrooms, also known as small pine mushrooms, are crispy and refreshing, and are the best on the table. Now its high-yield cultivation techniques are described as follows: 1. Raw material formula Brazil mushroom cultivation materials are relatively extensive. If calculated according to a cultivation area of ​​25 square meters, 500 kg of wheat straw, 250 kg of dried cow dung, 40 kg of cake fat and 30 kg of superphosphate are required. 5 kg of urea, 45 kg of lime and 15 kg of plaster. Second, the appropriate temperature for the growth of Brazilian mushroom mycelium is 8°C～34°C, and the suitable temperature for fruit body growth is 16°C～28.5°C. In spring cultivation, heap fermentation is generally built in early March and sown in late March or early April. The first step in composting is to soak the wheat straw and allow the wheat straw to absorb enough water. During the soaking process, add the appropriate amount of lime, calculated according to 50 kg of straw and 3 kg of lime. The second step is making manure. The dried cow dung and cake fat are broken and sifted. The dried cow dung and the cake fat are soaked in a urea solution. The humidity is suitable for holding in groups and landing to disperse, and then it is mixed and used. The third step is stacking. The water-absorbed wheat straw is first spread into a 0.3-meter-thick, 1-meter-wide, and 7.5-meter-long pile, then sprinkled with a layer of treated manure, and a suitable amount of fresh water is sprayed on the material surface. And so on, until the raw materials are finished. 4 to 5 days after the construction of the reactor, when the temperature in the reactor reaches about 70°C, the first turning operation is performed. During the turning process, the wheat straw and the manure must be fully mixed, and 1/2 of the gypsum should be added while turning over. After tumbling for 3 to 4 days, when the temperature in the material pile reaches 65°C, the second turning is performed, and lime water of 10 to 15 kg of lime is sprayed during turning. After another 4 days, the third turnover was performed, and all the superphosphate, the remaining gypsum, and the appropriate amount of lime were added while turning the stack (the pH of the culture was adjusted to 8.5). 3 days after the last turn, after the stack, do not press too hard in the stack, as much as possible in the heap on the air hole, when the pore disappears and there is a white mycelium when the cloth can be filled into the shed. Third, the thickness of the material for the cultivation of the material in the shop sheds for planting materials is 20-25 cm, and the temperature of the culture materials must not exceed 27°C-28°C. When sowing bacteria, first use 1â„2 of the bacteria in the lateral direction into the material, the depth of 4 to 6 cm, then spread the other half of the bacteria evenly on the surface, gently flatten . After sowing, the relative humidity in the shed was kept at about 70%, and the material temperature was kept at about 25°C. Fourth, after sowing, the first three days after the sowing of the soil, the mushroom shed should be closed. After 3 days, the ventilation of the mushroom shed should be increased. After 20 days, the hyphae should be long and the thickening of the silk surface should timely cover the soil. Before soiling, the soil is made into soil particles. The soil particles are coarse and fine. The coarse soil particles are 4 times the size of the fine soil particles, and the fine soil particles are the size of the soybean particles. Then, 50 kg of soil particles are added to 0.5 kg of lime, 50 The proportion of carbendazim was treated. The formaldehyde dilution was sprayed while mixing, and the soil particles were wetted and used after two days. Before the casing is covered with a layer of coarse soil particles, it is advisable to store the material surface immediately. After 2 days, appropriate amount of clarified lime water shall be sprayed. When the soil seam appears hypha (about 6 days), the soil particles shall be covered with a thickness of 3 cm. After the soil is covered, the soil is always kept moist. When there are a large number of villous hyphae, the amount of ventilation in the shed is increased, so that the surface of the soil is slightly dry, and the hyphae form a fruiting body. Fifth, fruiting management When a small number of fruiting bodies can appear after the water (ground spray, light spray), during which should be slightly ventilated. When the fruiting body grows to more than 3 cm, the water spray is stopped and the surface of the mushroom cover is dark brown and can be harvested when scales appear.
