Five elements of High-yield cultivation of volvariella volvacea

First, reasonably arrange the production season of straw mushroom is a high-temperature edible fungus. In order to make volvariella volvacea grow normally after sowing, the cultivation season should be carried out at a daily average temperature of more than 25 ℃. This is beneficial to the growth of mycelium and the development of fruiting body. Those with plastic greenhouse can be sown in advance to mid-May, and those with greenhouse mushroom can be cultivated all the year round. Second, choosing a favorable cultivation place can be cultivated both indoor and outdoor, but outdoor cultivation is more advantageous. In outdoor cultivation, the farmland with fertile soil, loose soil, ventilation and convenient drainage and irrigation should be selected, such as rape and watermelon as the most suitable cultivation place. The yield of wasteland is far lower than that of ripe and fertile land. Weeds should be removed before cultivation and Xiang Wai ditches should be opened so that they can be drained during waterlogging and irrigated during drought. Third, strict selection and treatment of culture materials, no matter what kind of raw materials are selected, they should be dry without mildew, and be exposed for 3 days before production. The newly harvested straw should be thoroughly dried, otherwise it will easily spoil and fail. The material was pre-wet with 5% lime water before sowing, the pH value was more than 12, and then the heap was fermented for 5 days, and the water content of the culture material substrate reached 65%. Fourth, the selection of excellent bacteria, such as increasing the amount of sowing, the genetic gene of the strain is very important in the production. The selection of high-quality and high-yield bacteria can obviously increase the yield. Such as Guangdong V23, V5, V17 and other high-quality strains. 5. Using scientific cultivation and management techniques, the "two-stage cultivation method" of disinfecting Ba soil, planting bacteria in bags, and then covering soil in small plastic arch shed or large plastic arch shed can obviously increase the yield. First, the rice straw raw materials can be packed and compacted, and the raw materials are closely connected, which is beneficial to the occurrence of bacteria, which avoids the malpractice of dead mushrooms caused by loose raw materials which often damage the mycelium and small mushroom buds when picking mushrooms; second, the temperature balance of the material can be adjusted from the increase or decrease of the number of layers in the code pile to promote the normal growth of mycelium. Third, by covering soil, the microclimate environment and physical structure in the mushroom field are improved, so that the fruiting body of straw mushroom is in a relatively stable environment from the formation of primordium to its growth and development, and is less disturbed by external adverse factors, which is beneficial to increase the yield. Fourth, after covering the soil, the nutrient elements in the soil can be fully utilized, especially through the infiltration and transport of soil water content to meet the water demand for the growth of volvariella volvacea, so as to achieve the goal of high quality and high yield. When straw mushroom is covered with soil, the bag should be placed flat, the distance between the bags is 5mi 10cm, the gap is filled, and the surface soil is 1.5ml 2.0cm. After covering the soil, enough water should be drenched at one time, so that the hyphae in the material can make full use of the water in the soil layer for the growth of mushrooms. In water management, first, do not replenish water when the entity is formed; second, do not directly replenish tap water or groundwater to avoid causing large temperature differences and mass death of mushrooms.
