First, scientific water, control high temperature and low temperature. The weather in spring is changeable. In terms of management, first, in the case of short-term high-temperature weather, Yangshuo should be planted with thick shades or wetted with water. At night, the film should be open and the air should be ventilated. The water spray should be performed sooner or later. The second is to spray enough water on the bed surface before the onset of the cold wave, and seal and compress the membrane to ensure the microclimate temperature within the membrane is stable. Third, in the rainy season with high relative humidity in the air, the two films should be lifted and vents should be opened on both sides to conveculate the air in the film while reducing the amount of water sprayed on the material surface. Fourth, the focus of water management should be to increase the moisture content of the inner matrix (moisture content reaches 70%), supplemented by water spray on the material surface, and use alternating wet and dry water methods.

Second, supplement nutrition, enhance metabolic function. When the temperature is below 15°C, add 3% soybean milk, 10% rice water, 0.1% potassium dihydrogen phosphate, and other nutrients (spray again after applying fertilizer) each time the water spray is combined with the water. Internal nutrition. In addition, plant ash and lime mixture (10:1) can be applied to the surface of the material, and antibacterial agents and insecticides (when no materials are on the surface of the bed) are regularly sprayed on the surface of the material and the mushroom field to prevent germs and insects. Breeding hazards.

Third, ventilation, promote the development of mushroom body. In addition to the establishment of a fixed ventilation point, should be combined with water or mushroom for ventilation, to reduce carbon dioxide and other harmful gases to a minimum.

Vitamin

Vitamins are a type of trace organic substances that humans and animals must obtain from food in order to maintain normal physiological functions. In terms of physiological functions, vitamins are neither a raw material for tissues nor a substance for supplying energy, but they are an indispensable substance for the body. It has many types and different chemical structures. Most of them are the components of the coenzyme (or prosthetic group) of certain enzymes. They are the indispensable compounds for maintaining the normal growth (growth, health, reproduction and production function) of the body. It plays a catalytic role in the body to promote the synthesis and degradation of major nutrients (proteins, fats, carbohydrates, etc.), thereby controlling metabolism. Vitamins are essentially low-molecular organic compounds. They cannot be synthesized in the body, or the amount synthesized is difficult to meet the needs of the body, so they must be supplied from the outside. The daily requirement of vitamins is very small (usually measured in milligrams or micrograms). They are neither a raw material for body tissues nor a substance for energy supply in the body. However, they do not regulate material metabolism, promote growth and development, and maintain physiological functions.
