The demand for phosphorus and potassium fertilizers during the soybean grain-bearing period is relatively large. During this period, these nutrients are taken from the soil below the tillage layer by the roots, and the nutrient conversion and release capacity in the soil under the tillage layer is weak, which leads to soybean nutrient. The demand does not harmonize with the soil fertility. It is prone to malnutrition and premature aging, which has become a major factor limiting the high yield of soybeans. Soybean grain fertilizer spraying fertilizer at root stage can relieve the contradiction between soybean requirement fertilizer and fertilizer supply, accelerate the accumulation, transformation and transportation of assimilation products. In this period, the root-spraying fertilizer can promote the translocation of nutrients to the grains, reduce and avoid the grains, promote full grain, increase grain weight, and increase yield. Soybean flowering begins and the absorption of phosphorus increases until it reaches maturity. Potassium can mainly regulate the physiology and biochemical function of plants, and cooperate with phosphorus in the late growth stage of soybean, accelerate the conversion of the material into a storage form, and promote grain swelling. Therefore, 0.5% urea + 0.4% potassium dihydrogen phosphate + 0.1% borax + 0.1% brown sugar mixed solution was sprayed outside the root of the soybean kernels, spraying once every 7 days to reduce pods, increase grain weight, and increase yield. There is a significant effect.
The fire-free cupping tool that is pumped into a vacuum and negative pressure state overcomes the shortcomings of traditional cupping. The main feature is that the tank is transparent, the negative pressure in the tank can be adjusted at will according to the patient's physical condition and condition, easy to observe the skin changes in the tank, easy to grasp the cupping time, safer to use, easy to operate, so it is not only suitable for hospitals, but also more extensive Is suitable for families.
