(1) The depth of the bottom fertilizer can reach 25 cm or more and is easily absorbed by the roots of the crop, thereby improving the utilization rate of the fertilizer. At the same time, after the deep application of the farmyard fertilizer, it can be decomposed in the deep layer of the soil, and activate the deep soil microorganisms, which is obvious to the improved soil. effect. (2) The autumn base fertilizer is beneficial to protect the soil moisture. After the autumn fertilizer is applied, the soil porosity is increased, the water holding capacity in the field is increased, and the winter and spring preservation effect is good. (3) It is conducive to the preservation of seedlings. Because of the application of fertilizer in autumn, most of the chemical fertilizers are turned into the deep and middle layers of the soil. The amount of surface chemical fertilizer is reduced correspondingly during spring sowing, the concentration of chemical fertilizer around the seeds is reduced, and the seed emergence rate is increased, which is beneficial to preserve seedlings. . (4) Enhance the lodging resistance of crops, the root development of crops has a strong fertility, and the combination of deep base fertilizer in autumn and shallow base fertilizer before spring sowing makes the fertilizer evenly distributed in the middle and lower layers of the soil, which is beneficial to the vertical and horizontal crops. stretch. The root system is developed, the water absorption and fertilizer absorption capacity is strong, the crop resistance to lodging and drought resistance is significantly enhanced, and at the same time, the early defermentation and premature aging of the crop is effectively prevented, and the effect of increasing yield and income is significant. (5) Alleviate the time of the farm, use the deep-rooted fertilizer in the autumn, and relieve the labor shortage in the spring.
