A kind of application method of crop basal fertilizer

Abstract

The invention discloses an application method for a crop base fertilizer. The application method is characterized in that when soil is ploughed, a furrow is ploughed out through a plow, the base fertilizer required by farmland is uniformly applied to the furrow bottom, the fertilizer is naturally covered by the soil which is ploughed out in a next round, then the base fertilizer is uniformly applied to a newly ploughed furrow, and the like. The method is mainly suitable for farmland base fertilizer application on upland soil and has the advantages that the ploughing and applying the base fertilizer are performed simultaneously, the method is convenient, simple and labor-saving, the pollution of the fertilizer to the environment can be reduced, the crop growth and development is facilitated, and the utilization efficiency of the fertilizer is improved.

Description

technical field [0001] The invention relates to a method for applying farmland base fertilizer and belongs to the technical field of farmland fertilization. Background technique [0002] At present, field crops in production vary according to the characteristics of the root system of the crops. Fertilization methods mainly include strip application, spot application, hole application, and spreading. A good fertilization method should not harm crops, prevent fertilizer loss, but also meet the needs of crops in a timely or continuous manner, and improve fertilizer use efficiency. Although several basal fertilizer fertilization methods that are currently being promoted can achieve a good effect of reducing the amount of fertilizer application and reducing the environmental pollution caused by excessive application, there are still the following deficiencies: [0003] 1. The fertilization and soil preparation process is labor-intensive and time-consuming. For example, strip fe...

Problems solved by technology

[0004] 2. The application of base fertilizer in holes is likely to cause the mixture of seed fertilizers to cause poisonous crop seeds, which is not conducive to germination and emergence

[0005] 3. It is difficult to spread the fertilizer evenly into the soil to a certain depth in the method of spreading the base fertilizer into the soil, and often there will be some fertilizer left on the soil surface, which will affect the fertilization effect

[0006] 4. When the base fertilizer is applied in strips and spots, the fertilization ditch and the fertilization hole are relatively narrow, so it cannot be applied when the amount of organic fertilizer is large
