What should we pay attention to when planting straw mushrooms in summer? Please guide the cultivation of volvariella volvacea in summer to pay attention to the following points: 1. In the nutritious bacteria bed or straw pile, the mycelium grows vigorously, the fruiting body is enlarged, the mushroom production period is long, and the yield and quality are good. Therefore, high quality and golden straw should be selected in the cultivation of straw mushroom, moldy and spoiled straw should not be used, and some organic matter such as soybean straw and dry manure powder of chicken, duck, pig and cow should be added to the straw pile to supplement nitrogen sources. it is beneficial to the high yield and high quality of straw mushroom. 2. Water deficiency is not only an important part of volvariella volvacea, but also all nutrients can be absorbed and utilized by mycelium only when dissolved in water, and the metabolites of volvariella volvacea can be excreted out of the body only when dissolved in water. Insufficient water will hinder the growth and development of volvariella volvacea, or even make it dry and die. However, if there is too much water, it will affect the ventilation of the culture material, inhibit the respiratory process, and lead to the death of a large number of hyphae and buds. Practice has proved that it is more suitable for the growth and development of straw mushroom hyphae when the water content in matrix or rice straw pile is about 65%. It is most suitable for the growth of straw mushroom fruiting body when the relative humidity of the air around the mushroom bed is 85% ~ 90%. 3. The spore germination and mycelial growth of volvariella volvacea generally do not need sunlight, but the formation of fruiting body needs sunlight. Diffuse light can promote the formation of fruiting body, promote its robust growth, increase its resistance to diseases and insect pests, promote the transformation and accumulation of pigments, and deepen the color of fruiting body. However, the strong direct light can inhibit the growth of the fruiting body. Therefore, straw mushroom cultivation in the open field must be covered with grass cover, and the site is suitable for sparse forest and shade land with "three points of yang and seven points of shade". 4. Volvariella volvacea is a kind of umbrella fungus with high temperature. The most suitable temperature for mycelium growth is about 32 ℃, the most suitable temperature for fruiting body growth is 30 ℃ ~ 32 ℃, and the temperature in straw pile is 35 ℃ ~ 38 ℃. Therefore, in the process of mycelium or fruiting body growth, when the air temperature is lower than or exceeds these temperature ranges, effective measures should be taken immediately to restore the normal growth temperature. 5. Air defense airflow passing through fast and sufficient oxygen is an important condition for the normal growth and development of volvariella volvacea. If oxygen is insufficient and carbon dioxide accumulates too much, mushroom buds often stop growing or die due to respiratory inhibition, but if the ventilation is too large, water is lost too quickly, which is also disadvantageous to the growth of volvariella volvacea. Therefore, it is best to cultivate volvariella volvacea in places where air convection is slow. 6. Acidity-alkalinity imbalance is an important factor affecting the growth and development of volvariella volvacea. Practice shows that the ph value most suitable for mycelium growth and development of volvariella volvacea is 7.2-7.5, and that for fruiting body formation and growth is about 7.4. the ph value most suitable for spore germination is 7.4-7.6, and excessive acidity or alkalinity will affect the normal growth and development of volvariella volvacea.
