According to the survey, due to excessive application of chemical fertilizers, less investment in organic fertilizers, and unreasonable farming practices, the thinner the soil, the more fertile soil fertility is imperative. The cultivation and improvement of soil fertility should start from two aspects: soil environmental conditions and soil properties. There are six ways:
1. Do a good job in the basic construction of farmland According to the contradiction that restricts the improvement of soil fertility, various farmland basic construction measures for water control and soil improvement should be adopted according to local conditions. In the process of renovating the soil environment, fertilize the soil and increase the soil fertility.
2, the use of biological soil improvement Afforestation to maintain water and soil, conserve water sources, regulate rainfall, reduce water and drought disasters, and establish a solid foundation for fertilizing soil. The use of green manure to fertilize soil fertility is an effective measure to cultivate land and improve the physical and chemical shape of the soil.
3. Adding fertilizer to soil The addition of farmyard fertilizer has a special effect on improving soil fertility. Farmyard manure can improve the physical and chemical shape and cultivation performance of the soil, enrich the plant nutrient elements, and promote the activities of beneficial microbes in the soil, which is conducive to water retention and fertilizer retention and increased permeability.
4. Tillage and soil improvement The cultivation measures such as tillage, alfalfa, grinding and pressing with deep tillage as the center are one of the important measures to accelerate the maturity of the soil and to orient the soil. Through deep tillage, the soil tillage layer can be thickened and the soil can be improved. Structure to improve ground power.
5, the soil to soil change The use of ditch and alkali, sand mixed with mud and drought to change the paddy field and other methods, the variable sand alkali is fertile.
6, the crop is inverted. "The mouth is inverted, it is better than the manure." The correct rotation of the crop can make the nutrients and water in the soil be rationally utilized, and give full play to the good effect of biological cultivation and fertilization. At the same time, it can also reduce the harm of pests and diseases to crops and promote high yield and good harvest.
