It is necessary to strengthen and improve various technical measures in formula fertilization. In the process of formula fertilization, it is necessary to fully improve the fertilization parameters, such as the amount of nutrient absorption per unit of output, soil nutrient utilization, fertilizer utilization, etc. These parameters are constantly changing along with changes in production conditions, based on the original test soil and plant nutrient requirements. At the same time, new environmental conditions analysis items (such as water quality, soil hazardous material content, fertilizer and pesticide pollution, etc.) have been added to continuously enrich fertilization parameters and optimize formula fertilization. To increase the proportion of organic fertilizer in formula fertilization. Organic manure has the characteristics of complete nutrients, long-term fertilizer efficiency and no pollution. High-efficiency organic manure can increase soil organic matter content, improve soil water storage and fertilizer retention capacity, improve soil physicochemical properties and aggregate structure, and improve the quality of agricultural products. It is necessary to increase the use of trace fertilizers and biological fertilizers. Micro-fertilizer can balance the nutrients needed for crops, and biological fertilizers can secrete physiologically active substances through the micro-organisms they contain. They can fix nitrogen, dissolve phosphorus, release potassium, decompose other micronutrients in the soil, and increase fertilizers and organic fertilizers. The utilization rate improves soil physical and chemical properties so that soil can supply various nutrients to crops, promote crop growth, increase crop yield and product quality, and at the same time decompose harmful chemical substances in the soil and kill harmful bacteria and reduce fertilizers. Residues of pesticides and harmful bacteria. To coordinate the relationship between a large number of elements and trace elements. In formula fertilization, people often attach importance to the use of nitrogen, phosphorus, and potassium, while neglecting the application of trace element fertilizers. The addition of trace elements or sprays of trace element growth agents and composite biological growth agents can provide balanced supply of nutrients, promote rapid transformation of nutrients in crops, reduce the accumulation of harmful substances, and promote disease resistance, disease prevention, and increase production of crops. A good way to improve quality. It is necessary to change the past traditional methods in crop fertilization and turn blind fertilization into optimized formula fertilization.
