What are the functions of biochemical fulvic acid? Please give an introduction to biochemical fulvic acid can refer to the following introduction: first, drought resistance and water saving, resistance and disaster reduction. The period of validity of fulvic acid inhibiting plant transpiration can last more than 28 days, and the plant respiratory pore can be properly closed 24 hours after spraying, and the plant transpiration intensity can be reduced by about half after 5 days. Greatly control the transpiration of water and nutrients in the plant, so as to achieve the purpose of increasing revenue and saving expenditure, drought and water saving, and greatly improve the resistance of crops to adverse environment. Second, improve the physical and chemical properties of soil. Because there are many active functional groups in fulvic acid, it can keep the soil loose. Fulvic acid is used as an additive to produce compound fertilizer and foliar fertilizer, which can activate soil, activate solidified nutrient elements and ensure soil activity. Third, improve the utilization rate of chemical fertilizers and the efficacy of pesticides. Fulvic acid has low molecular weight and strong permeation function, and can be mixed with pesticides to form pesticide complexes. The addition of fulvic acid to chemical fertilizers and pesticides has obvious synergistic effect on chemical fertilizers and pesticides, but also can reduce the amount of pesticides and fertilizers, and the economic benefit is remarkable. Fourth, stimulate crop growth. Fulvic acid can stimulate the growth and development of crops, which is a characteristic that fulvic acid does not have. Seed soaking, root dipping, spraying and root application can stimulate the growth and development of crops and promote the early ripening of crops. Fifth, improve the quality of agricultural products. The application of fulvic acid to crops can promote the accumulation of dry matter, improve its quality, accelerate the speed of coloring and expansion, increase Vc content and sugar content, and promote the formation of starch and protein. Sixth, inhibit the growth of harmful bacteria. Fulvic acid can promote crop growth, thus improving the disease resistance of crops. In addition, fulvic acid itself can inhibit many bacteria, especially on plant Fusarium wilt, Verticillium wilt and rot. Seventh, strong complexing ability. Fulvic acid has certain chelating ability and good complexing ability to trace elements. After chelating with insoluble trace elements, fulvic acid has higher solubility and is easily absorbed by crops. The performance of foliar fertilizer products chelated with a large number of elements is stable. Fulvic acid as a fungicide, regulator carrier and additive can not only improve the efficacy by more than 30%, but also provide rich nutrients for plant growth.
