The deep application of chemical fertilizers is based on the law of fertilizer requirements of the crops and the nature of the soil, the use of formula fertilization techniques and the principle of fertilizer rhizosphere effect, the application of chemical fertilizers to the plough layer to a certain depth, in order to facilitate the better absorption of crops, reduce volatile losses of fertilizers, improve fertilizer utilization For the purpose of a fertilization method. The application of chemical fertilizer deep mechanization is more effective. The mechanized deep application of chemical fertilizers is accomplished in the process of mechanized cultivating land, soil preparation, sowing, cultivating, etc., and simultaneously completing the operation of deep chemical fertilizers, and using mechanical methods to control the depth, location, quantity, and other technical indicators of fertilization. Because the deep application of chemical fertilizers is distributed in the effective rhizosphere of crops, it is beneficial to the crops to better absorb and reduce the volatilization losses caused by surface fertilizers or shallow application of chemical fertilizers. The average nitrogen fertilizer utilization rate can be increased from 30% to 40%. The deep application of phosphorus and potassium fertilizers can reduce wind erosion loss, promote absorption, extend fertilizer efficiency, and generally increase production rate by 5%-15%. Mechanized deep application can also avoid burning seed and improve efficacy to reduce pollution. Fertilizer deep application can be divided into three categories: Base fertilizer deep application. There are two methods for deep-fertilizing the base fertilizer: one is to fertilize the soil first; then the second is to apply the chemical fertilizer to the furrow while plowing and turning. The required fertilization depth is 6 cm, and the width of the fertilizer belt is 3-5 cm. The rows of fertilizers are evenly distributed, and there are no obvious broken strips. Fertilizer deep application. Fertilizer deep seeding requirements of species, between the fertilizer can form a certain thickness, generally more than 3 cm, to meet the seedling growth needs of nutrients, can avoid the risk of burning, burning seedlings. Top dressing. The top dressing is applied between 10-20 cm from both sides of the plant line. The method of opening a small ditch or punching hole should be 6-10 cm in depth and the fertilizer should have a width of 3 cm or more. Pay attention to the soil after fertilization. Nursing pad is a disposable sanitary product made of PE film, non-woven fabric, fluff pulp, polymer and other materials.
