1. Strengthen and improve various technical measures in formula fertilization. In the process of formula fertilization, it is necessary to enrich and improve the fertilization parameters, such as nutrient uptake per unit of yield, soil nutrient utilization rate, fertilizer utilization rate, etc. These parameters are also constantly changing with the changes of production conditions, based on the original test of soil and plant nutrient requirements. In addition, new environmental conditions analysis projects (such as water quality, soil harmful substances content, chemical fertilizers and pesticides pollution, etc.) are added to continuously enrich and improve fertilization parameters and optimize formula fertilization.
2. To increase the proportion of organic fertilizer in formula fertilization. Organic fertilizer has the characteristics of full nutrient, long-lasting fertilizer and no pollution. High-efficiency organic fertilizer can increase soil organic matter content, improve soil water storage and fertilizer retention capacity, improve soil physical and chemical properties and aggregate structure, and improve the quality of agricultural products.
3. To increase the use of micro-fertilizers and biological fertilizers. Micro-fertilizer can balance the nutrients needed by crops, and bio-fertilizer can secrete physiologically active substances through micro-organisms contained in it, which can fix nitrogen, dissolve phosphorus, dissolve potassium, decompose other micro-nutrients in soil, and improve chemical fertilizers and organic fertilizers. The utilization rate improves the physical and chemical properties of the soil, enables the soil to supply various nutrients to the crop, promotes crop growth, improves crop yield and product quality, and at the same time decomposes harmful chemicals in the soil and kills harmful bacteria, reducing fertilizer, Residues of pesticides and harmful bacteria.
4. Coordinate the relationship between a large number of elements and trace elements. In formula fertilization, people often pay attention to the use of a large number of elements such as nitrogen, phosphorus and potassium, while ignoring the application of trace element fertilizer. The application of trace elements or sprayed trace element growth agents and composite biological growth agents can balance the supply of nutrients, promote the rapid transformation of nutrients in crops, and reduce the accumulation of harmful substances, which is to promote crop disease resistance, disease prevention and increase yield and increase. Good way of quality
5. In the crop fertilization, it is necessary to change the traditional way in the past, and change the blind fertilization to optimize the formula fertilization.
