After the Spring Festival is over, the rainy season has passed, the temperatures around the country have risen, and the wheat greening period has arrived. Farmers who grow wheat should chase water and topdress in time to ensure increased production and income. Let's share the winter wheat greening and topdressing technology for everyone. Fertilization principle First of all, according to the growth of seedlings, nitrogen fertilizer should be applied in several stages, and the proportion of application in the middle and late stages of jointing should be appropriately increased; the amount and time of topdressing should be scientifically determined according to the amount of base fertilizer application, seedling condition, temperature and soil fertility; top dressing. At the same time, according to soil moisture and water retention and fertilizer retention capacity, the amount and time of irrigation should be reasonably determined to achieve integration of water and fertilizer management. In addition, it is necessary to seize the favorable opportunity for wheat to return to green, to take timely measures to promote the transformation of weak seedlings and increase the rate of seed formation; to control the long field to prevent the late fall. Fertilization advice Before returning to green, the total number of stems per acre is less than 450,000, and the three types of wheat fields with lighter leaf color and poor growth are timely: fertilizer and water management should be carried out in time, and spring topdressing can be carried out twice. For the first time in the greening period, 5-8 kg of urea was applied per acre with watering; the second time was 5-10 kg of urea per acre with watering at the jointing stage. Before returning to green, the total number of stems per acre is between 45,000 and 600,000. The second group of wheat fields with a small population: in the period of wheat uplift, combined with watering, 10 to 15 kg of urea per mu. Before returning to green, the total number of stems per acre is between 60,000 and 800,000. A suitable group of wheat fields can be combined with watering for 12 to 15 kilograms per acre during jointing. Before returning to green, the total number of stems per acre is more than 800,000, the color of the leaves is dark green, and there is a tendency to grow. The cultivating should be carried out during the regreening period, delaying the application of nitrogen fertilizer and reducing the amount of nitrogen fertilizer, controlling the group length, preventing lodging and corruption. Late ripe. Generally, 8 to 10 kg of urea can be applied per mu in the late stage of jointing. Wheat damaged by early spring freezing: 5-10 kg of urea should be applied immediately and watering should be carried out to promote early tillering of wheat, increase tillering rate and reduce the loss of freezing damage; many farmers do not squat after rotary tillage, resulting in deep sowing of sowing. Weak seedlings, less tillers, and weak seedlings: It is recommended to apply urea 10 to 15 kg during the returning period; wheat fields in the sulfur-deficient area: if the base fertilizer is not applied with superphosphate, potassium sulfate, sulfur-based compound fertilizer, etc., it should be the first When applying the top dressing, choose ammonium sulfate, and the amount of sulfur applied per mu is about 2 kg. At the same time, it is necessary to apply the diammonium phosphate to the base fertilizer without applying phosphate fertilizer or phosphorus deficiency field; for the field where no potassium fertilizer or less application is applied, it is recommended to apply nitrogen and potassium compound fertilizer in the greening or jointing stage, combined with the control of sheath blight The method of one spray and three preventions is to compensate the phosphorus and potassium fertilizers by root dressing; if there is no irrigation condition or no effective precipitation, the leaves can be sprayed with urea and potassium dihydrogen phosphate in the spring to play the role of fertilizer. In addition, potassium dihydrogen phosphate, boron fertilizer and zinc fertilizer can be sprayed on the foliar surface of wheat during grain filling to prevent dry hot air and lodging, increase grouting strength and increase grain weight.

In many cases, after a course of treatment with red infrared light, the pain is gone.
Red light therapy works by stimulating the mitochondria in the body's cells, which are responsible for producing energy (ATP). The light energy absorbed by the mitochondria triggers a series of biochemical reactions that can enhance cellular metabolism and promote various therapeutic effects.

The energy can flow through the body and interact with damaged cells in many parts of the body operating more like a vitamin that goes where it needs to go. This wavelength is also best for treating the lymph system and acupuncture points. Whereas studies show near-infrared wavelengths in the 850 nm penetrate deeper through skin and bone for relief of chronic pain.
As with red light therapy, near infrared light therapy does not mask the symptoms of pain, it encourages the healing of the actual cause of the pain. Once absorbed, the light energy kicks off a whole series of metabolic events, stimulating the body`s natural processes on a cellular level. There is an increase in blood flow, allowing the parts of the body to receive the oxygen and nutrients they need in order to function more effectively. Regeneration is stimulated. Inflammation and pain are reduced.
Some potential benefits of red light therapy include:
1. Skin health: It can improve the production of collagen and elastin, leading to improved skin tone, reduced wrinkles, and acne treatment.
2. Pain relief: It may help reduce inflammation and alleviate pain in conditions such as arthritis, muscle strains, and joint pain.
3. Wound healing: Red light therapy can promote tissue repair and accelerate wound healing by stimulating cell growth and circulation.
4. Hair growth: It has shown potential in stimulating hair growth and treating conditions like androgenetic alopecia (pattern baldness).
5. Mood enhancement: Red light therapy may have positive effects on mood and mental well-being by improving serotonin levels and reducing symptoms of depression and anxiety.
