What should be noted when growing straw mushrooms in summer? Please advise
When growing straw mushrooms in summer, note the following points:
1. Prevent insufficient nutrition. In a mushroom bed or straw pile with sufficient nutrition, the mycelium grows vigorously, the fruiting bodies are plump, the mushroom-producing period is long, and both yield and quality are good. Therefore, when cultivating straw mushrooms, choose high-quality, golden-yellow rice straw; do not use moldy or spoiled rice straw, and add some soybean stalks and dried manure powder from chickens, ducks, pigs, and cattle, as well as other organic matter, to the straw pile to supplement nitrogen sources, which helps achieve high yield and good quality in straw mushrooms.
2. Prevent insufficient water. Water is not only an important component of straw mushrooms, but all nutrients can be absorbed and used by the mycelium only after dissolving in water, and the metabolic products of straw mushrooms must also dissolve in water to be excreted from the body. Insufficient water will hinder the growth and development of straw mushrooms and may even cause them to dry up and die. However, if there is too much water, it will affect the aeration of the substrate, inhibit respiration, and cause large numbers of mycelia and mushroom buds to die. Practice has shown that when the water content in the substrate or straw pile is about 65%, it is more suitable for the growth and development of straw mushroom mycelium. When the relative humidity of the air around the mushroom bed is 85%-90%, it is most suitable for the growth of straw mushroom fruiting bodies.
3. Prevent direct sunlight. The spore germination and mycelial growth of straw mushrooms generally do not need sunlight, but the formation of fruiting bodies does need sunlight. Diffused light can promote the formation of fruiting bodies, promote their robust growth, increase their resistance to pests and diseases, promote the transformation and accumulation of pigments, and deepen the color of the fruiting bodies. However, strong direct light inhibits the growth of fruiting bodies. Therefore, straw mushrooms cultivated in the open field must be covered with a straw mulch, and the site should preferably be sparse forest shade with "three parts sun and seven parts shade."
4. Prevent unsuitable temperature. The straw mushroom is a high-temperature type agaric mushroom. The most suitable air temperature for mycelial growth is about 32°C, the most suitable air temperature for fruiting body growth is 30°C-32°C, and the temperature inside the straw pile is most suitable for fruiting body development at 35°C-38°C. Therefore, during the growth of the mycelium or fruiting bodies, 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. Prevent air flow from being too fast. Sufficient oxygen is an important condition for the normal growth and development of straw mushrooms. If oxygen is insufficient and carbon dioxide accumulates too much, the mushroom buds often stop growing or die because respiration is inhibited; however, if the ventilation is too great, water disperses too quickly, which is also unfavorable for straw mushroom growth. Therefore, it is best to choose a place with slow air convection for cultivating straw mushrooms.
6. Prevent pH imbalance. pH is an important factor affecting the growth and development of straw mushrooms. Practice has shown that the most suitable pH for the growth and development of straw mushroom mycelium is 7.2-7.5; the most suitable pH for the formation and growth of fruiting bodies is about 7.4; and the most suitable pH for spore germination is 7.4-7.6. Too much acidity or alkalinity will affect the normal growth and development of straw mushrooms.
