1. It is good for improving the soil. The deep-growing winter irrigation in white land has a long time of soil weathering, which is conducive to the transformation of organic fertilizer nutrients. After winter and early spring freezing and thawing, the soil becomes loose and has good air permeability, which is conducive to soil microbial activity, increased aggregate structure, and improved soil ploughing. 2 is conducive to water conservation. After deep plowing in winter and irrigation in winter, the deeper layers of soil can accumulate more water and increase the amount of water in the soil. Most parts of our province have more drought and less rain in spring. Deep-throwing winter irrigation can play the role of winter water spring and winter water and summer water use. It eases the conflict of water use in spring and guarantees sufficient bottom sill at the time of sowing, which is conducive to timely planting of spring sowing crops and early emergence of seedlings. Seedling early. 3 is conducive to raising the temperature. Early and late excavation of spring crops and the speed of growth depend on the temperature of the ground and the quality of the lyrics. The winter irrigated arable land at the end of the crop, the ground temperature is high, generally 2-3 days early, so that the early development of the crop, root development, vegetative growth Have an important role. 4. Helps eliminate pests. White winter water has a large amount of water and a long period of water accumulation, which has significant inhibition and killing effects on overwintering pests in the soil. For spring sowing commercial crops such as peanuts and cotton fields, deep plowing and winter irrigation can expose the main pests such as bollworms, earthworms and earthworms to the surface and freeze to death, which can effectively reduce the overwintering base number of pests. In the plots plowing deep into winter irrigation, the mortality rate of overwintering pests is as high as 80%, and that of plots that are not cultivated or irrigated is only around 30%. 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.
