In recent years, the state has strongly advocated the use of organic fertilizers in agricultural production. However, there are still a few people who disagree with this issue. They are still fertilizing the soil in accordance with traditional concepts, which not only pollutes the soil but also affects the quality and yield of crops. Recently, the reporter interviewed Shi Chunxi, a researcher at the Plant Protection College of Northwest Agriculture and Forestry University, and asked him to talk to farmers about the mystery of organic fertilizers.
Soil nutrient sources Organic matter contains various nutrients required for crop growth, providing nitrogen, phosphorus, potassium and various trace elements for crop growth. In addition, the carbon dioxide produced by the decomposition of soil organic matter can provide conditions for the photosynthesis of green plants.
Promoting the growth and development of crops Humic acid in organic matter can enhance plant respiration, increase the permeability of cell membranes, and enhance the absorption of nutrients. At the same time, vitamins and some hormones in organic matter can promote plant growth and development.
Improved humus in soil organic matter contributes to the formation of a good structure of clay soil, changing the soil pore conditions and the ratio of water and gas, and creating suitable soil tightness.
Improve soil fertility The organic colloids in soil organic matter can adsorb a large amount of cations and water, and their cation exchange capacity and water absorption rate are several times or even several times larger than those of clay, so it can increase the efficiency of soil conservation and water storage. The ability to increase the soil's acid and alkali buffering capacity.
Increasing the humus in the soil nutrient organic matter has a complex effect and helps to eliminate soil contamination. For low-yielding fields, fertilizing the soil and increasing the level of soil fertility can be achieved by increasing the content of organic matter. For high-yielding fields, due to the continuous decomposition of organic matter, it is also necessary to continuously supplement organic matter. Humic energy forms complexes or chelates with phosphorus, iron, and aluminum ions, avoids the precipitation of insoluble phosphates, and increases the amount of available nutrients. When Chunxi proposed, it should change the concept of fertilization, increase organic fertilizers, improve soil organic matter content, in order to give full play to the role of fertilizer production.
