The amount of organic fertilizer applied is insufficient. With the improvement of rural conditions, the enthusiasm of farmers to build farmyard manure has decreased, and the aquaculture industry has gradually shifted from farmer households to large-scale breeding. The number of farmer manure and manure has decreased, while the utilization rate of large-scale livestock and poultry manure resources is not high. The amount of organic fertilizer applied is insufficient. The structure of chemical fertilizer application is unreasonable. Many farmers have more serious problems of blind fertilization, resulting in increased tillering, weak stems, reduced resistance to cold, cold, and disease resistance. They are often exposed to winter frost damage and spring cold damage. In the middle and late stages, pests and diseases are aggravated and easily fall, which affects production. Straw returning to the field does not increase nitrogen fertilizer. Returning straw to the field is an effective measure to solve the problem of organic fertilizer deficiency, but many farmers do not grasp the technology, and do not increase the application of nitrogen fertilizer after the straw is returned to the field. The fertilization method is unreasonable. In some low-yield fields or poor soil areas in winter wheat producing areas, there is a “one-shot†fertilization method, that is, the whole planting period is applied to the soil, and all the fertilizers are applied to the soil at one time, and no longer topdressing during the growth period. Improper time of topdressing. In most winter wheat fields, spring topdressing is carried out in the regreening stage. Early spring is the key period for wheat spring tillering and basal internode elongation. Premature topdressing often results in excessive inefficient tillers, wheat field population is too large, stems are weak, base The internodes are too long; it will also cause the field to be closed in the middle and late stages of wheat growth, poor ventilation and light transmission, and the disease such as powdery mildew will be aggravated, which will lead to lodging in the later stage and affect the yield and quality of wheat. New fertilizers are applied blindly. Some of the scientific and technological content is not high and excessive speculation, which makes the farmers unclear, blindly applied in the case of unclear investment direction and unclear application methods, resulting in reduced production and economic losses.

Compared with traditional treatment, red light therapy is a non-invasive treatment method. It is non-invasive, painless, does not require medication, has no side effects and many other advantages. Generally speaking, its use does not require professional knowledge and operation, and is easy to use, so many people also use it as a treatment method for home care, or commercial use, such as SPA center, rehabiliation center, etc. Red light therapy generally uses a 600-700nm red light band LED combined with a 700-1000nm infrared band LED. The red light band acts on 3-4cm skin surface, and the infrared can penetrate deeper to 6-9cm bones. After being irradiated with red light and infrared light, the human body promotes a series of biochemical reactions in the body, mainly manifested in promoting the activity of cell mitochondria and generating more ATP and oxygen at the cellular level. The effects of red light therapy include: 1. Promote cell metabolism: accelerate cell growth and repair, and help wound healing. 2. Improve blood circulation: increase blood flow, increase oxygen supply and nutrient supply to tissues. 3. Reduce inflammatory response: It has a certain relief effect on inflammatory diseases such as joint inflammation and skin inflammation. 4. Pain relief: Reduce pain sensation by regulating the release of neurotransmitters So far, we have helped many clients rebuild their health, helped them achieve their goal of becoming thinner and more beautiful, and many people have invested in it to earn more income.
