Straw mushroom, also known as orchid mushroom, is one of the more common species of fungi cultivated in China. The straw mushroom contains Vc and a variety of amino acids, is rich in nutrients, and has a unique flavor. It is a variety with short production cycle, fast effect, low investment and high benefit. In the hot summer season, fresh mushroom species on the market are rare, and straw mushroom can not only regulate the market supply of off-season mushrooms and meet people’s ever-increasing living demands, but also can earn foreign exchange through exports after deep processing. Straw mushroom is a saprophytic fungus. It must absorb ready-made nutrients and water from the dead plants and soil to live. Therefore, the relevant experts reminded the mushroom farmer that it was necessary to meet the needs of the straw mushroom for the growth conditions before it could be cultivated successfully. It must be guarded against the lack of necessary and inappropriate results. Insufficient 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 source, carbohydrates, minerals and so on. 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 mushroom, should choose high-quality, golden yellow straw, should not use rotten spoilage of straw, and add some soy straw and chicken, duck, pig, cattle dung dry powder and other organic matter in the straw to supplement Nitrogen source is conducive to high yield and high quality. There is not enough waterproof. 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. It may even cause it to die, but if it is too much water, it will affect the ventilation of the culture, inhibit the respiration process, and cause a large number of deaths of mycelium and buds. Practice has proved that the moisture content in the matrix or straw stack is about 65% more 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 fruit body. Protect against direct 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 on the open grass, the site to select "three points Yang Qifenyin" sparse forest is appropriate. Prevent temperature discomfort. Pleurotus eryngii is native to tropical and subtropical regions and is a type of high-temperature agaric. The temperature range for mycelium growth is 20°C-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 is optimal at 35°C-38°C for fruit body development. 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. Anti-air flow passes quickly. The straw mushroom is a saprophytic organism that likes the air, and sufficient oxygen is an important condition for the normal growth and development of the 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 disperse too quickly, which will also adversely affect the growth of straw mushroom. Therefore, it is best to choose the place where the air convectively grows. Anti-acidity imbalance. The pH value is an important factor that influences the growth and development of the straw mushroom. Practice has proved that the optimum pH value for the growth and development of the mycelium of the straw mushroom is 7.2-7.5; the optimum pH value for the formation and growth of the fruit body is about 7.4; the optimum germination of the spores PH value of 7.4-7.6, such as acidity or alkalinity, will affect the normal growth and development of straw mushroom.
