Avoid excessive fertilization with countermeasures
the reason Deterioration of soil properties Large amounts of single-element fertilizers are applied to farmland. Nutrients cannot be effectively absorbed and utilized by crops. Nitrogen, phosphorus, and potassium are easily contaminated by the soil and form various chemical salts, which accumulate in the soil and cause soil. The imbalance of nutrient structure and physical traits have deteriorated, and some of the harmful metals and harmful bacteria in the plot have exceeded standards, leading to deterioration of soil properties. Long-term excessive application of nitrogen fertilizer can also cause the loss of calcium, magnesium and other elements, so that the soil acidification, and ultimately lose productivity. This leads to a decline in the quality of the product and the application of certain chemical fertilizers, resulting in malnutrition of the crop, impaired synthesis and synthesis of some substances in the body, and results in a decrease in the quality of the product. For example, the current fruits are not sweet to eat, the vegetables are not fragrant, and they are easily rot and cannot be stored. The reason for this is excessive application of chemical fertilizers. As a result of environmental pollution, due to the excessive application of chemical fertilizer, soil water-soluble nutrients and other substances are leached into groundwater and rivers by rainwater and farmland irrigation, resulting in contamination of groundwater and rivers in some areas, and eutrophication of groundwater, rivers, and lakes. The groundwater is not good to drink, and fish and shrimp in some rivers and lakes often die. The increase in production costs is limited by factors such as the cultivation level of cultivation and the amount of fertilizer required by crops. The crop cannot obtain high yields. Second, due to the excessive application of a single fertilizer, resulting in imbalance of nutrients and malnutrition. Only increasing the cost does not increase the output, and causes the low-quality agricultural products to be difficult to sell or the price is low, thus causing losses to the farmers. Countermeasures In the fertilization of crops, we must change the traditional methods of the past and change blind fertilization to optimize fertilization. It is necessary to strengthen and improve various technical measures in formula fertilization. In the process of formula fertilization, it is necessary to enrich and perfect fertilization parameters, such as nutrient absorption per unit yield, soil nutrient use efficiency, and chemical fertilizer utilization rate. These parameters are also changing along with the changes in production conditions, which are the basis for 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 large quantities of nitrogen, phosphorus, and potassium, while neglecting the application of trace element fertilizers. The addition of trace elements or spraying 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 and increase of crops.
