Summer mushrooms must be six defense
A lack of nutrition. Nutrition is the material basis for the growth and development of straw mushroom, and it is an important condition for high yield and high quality. The nutrition of straw mushroom is mainly nitrogen sources, carbohydrates, minerals, and physiologically active substances. In a well-fed mushroom bed or haystack, the mycelium grows vigorously, the fruit body is hypertrophied, the mushroom production period is long, and the yield and quality are good. Therefore, in the cultivation of straw mushrooms, should choose high-quality, golden yellow straw, should not use the rotten metamorphosis of straw, and in the straw heap add some soybean straw, chicken, ducks, pigs, cattle dung powder and other organic matter, to supplement Nitrogen source is conducive to high yield and high quality. Second, there are insufficient waterproof points. Water not only constitutes an important part of straw mushroom, but also all nutrients can be absorbed and utilized by the mycelium only when dissolved in water. The metabolites of straw mushroom must also be dissolved in water to be excreted from the body. The lack of water will hinder the growth and development of straw mushroom. And even make it dry and dead. However, if there is too much water, it will affect the ventilation of culture materials, inhibit the respiratory process, resulting in a large number of death of mycelium and buds. Practice has proved that the moisture content in the substrate or straw is about 65% suitable for the growth and development of the mushroom mycelium. The relative humidity of the air around the mushroom bed is 85%~90%, which is most suitable for the growth of grass mushroom fruiting bodies. Three against sunlight. Spore germination and mycelial growth of straw mushroom generally do not require sunlight, but the formation of fruit bodies requires sunlight. Under completely dark conditions, it is difficult to form fruit bodies. Diffuse light can promote the formation of fruit bodies and promote its robust growth, increase resistance to diseases and insect pests, promote the accumulation of pigments, and make the color of fruit bodies darker. However, strong direct light has an inhibitory effect on fruiting bodies. Therefore, the cultivation of straw must be covered with grass cover on the open field, and it is advisable to use the sparse shade under the sunlight that can be selected by the “three-points and seven-points†shade. Four anti-temperature discomfort. The straw mushroom is native to tropical and subtropical regions and is a type of high-temperature agaric. The temperature range for mycelium growth is 20°C to 40°C, and the optimum temperature is about 32°C. The optimum temperature for fruit body growth is between 30°C and 32°C. The temperature within the haystack develops at a suitable fruit body of 35°C to 38°C. Therefore, when the mycelium or fruit body is below or exceeds its temperature range during the growth process, powerful measures should be taken immediately to restore the normal growth temperature. Five to prevent rapid air flow through. Straw mushroom is a joyous saprophytic bacterium, and sufficient oxygen is an important condition for the normal growth and development of straw mushroom. If oxygen is insufficient and carbon dioxide is accumulated too much, mushroom buds often stop growing or die due to respiration inhibition. However, if the ventilation is too large, the water will be dispersed too quickly, which will also be detrimental to the growth of straw mushroom. Therefore, it is best to choose the place where the air convectively grows. Six anti-acid alkalinity imbalance. The pH value is an important factor that influences the growth and development of straw mushroom. Practice has proved that the optimum pH for the growth and development of straw mushroom mycelium is 7.2-7.5, the optimum pH for the formation and growth of fruit bodies is about 7.4, and the optimum pH for spore germination is 7.4-7.6, if the pH is too large, it will affect the normal growth and development of straw mushroom.
