Description

Technical Field

[0001] The invention belongs to the technical field of fertilizer application equipment, and in particular relates to a single-row powdered solid fertilizer application machine. Background Art

[0002] Solid fertilizer is a commonly used type of fertilizer in agricultural production, which includes various organic and inorganic fertilizers, such as compost, farmyard manure, compound fertilizer, etc. Solid fertilizer fertilization technology mainly involves the design of fertilization machinery, the optimization of fertilization methods, and the selection of fertilization timing. With the development of agricultural mechanization, the design of solid fertilizer fertilization machinery is becoming more and more mature.

[0003] The existing solid fertilizer applicators either bury the solid fertilizer directly into the soil, or dig trenches in the soil, collect the soil in the trenches and mix it with the solid fertilizer, and then fill it back into the trenches. Directly burying solid fertilizer in the soil will cause the solid fertilizer to aggregate and cannot be evenly released into the soil. The method of mixing soil with solid fertilizer and then filling it back will cause some solid fertilizer to be on the surface of the soil and be directly exposed to sunlight. The ultraviolet rays and high temperature in the sunlight will accelerate the volatilization and decomposition of certain components in the solid fertilizer, resulting in reduced fertilizer efficiency. Summary of the invention

[0004] In view of the above-mentioned problems, the purpose of the present invention is to provide a single-row powdered solid fertilizer applicator, which can not only mix soil and solid fertilizer and then backfill them into the ditch, but also cover the backfilled soil with a layer of soil with adjusted humidity, so that the solid components are evenly distributed, while avoiding volatilization of components caused by direct sunlight, and can also conserve soil moisture.
