Layered fertilizer applying device

Abstract

The invention discloses a layered fertilizer applying device. The layered fertilizer applying device comprises a first fertilizer applying assembly and a second fertilizer applying assembly, wherein afertilizer inlet of the first fertilizer applying assembly and a fertilizer inlet of the second fertilizer applying assembly are communicated with a fertilizer box; and a fertilizer outlet of the second fertilizer applying assembly is positioned above the fertilizer outlet of the first fertilizer applying assembly. The layered fertilizer applying device can perform layered multi-dimensional fertilizer application on soil to improve absorption effect, on fertilizers, of seeds, so that follow-up processes such as budding, seedling grow-up of the seeds are facilitated; the layered and multi-dimensional fertilizer applying mode can improve a fertilizer utilization rate, can reduce waste of fertilizers, is more environmentally friendly, and can relieve or avoid soil hardening; and detecting and regulating devices are arranged, so that fertilizer applying depth of the layered fertilizer applying device can be automatically regulated according to ground height changes, and therefore, unification and stability of fertilizer applying depth are guaranteed, and the fertilizer applying effect is improved in a facilitated mode.

Description

technical field [0001] The invention relates to an agricultural mechanical equipment, in particular to a layered fertilization device. Background technique [0002] Corn, wheat, potato and other crops often need to be fertilized at the same time when sowing, so as to ensure that the seeds of the crops can absorb sufficient nutrients during germination and seedling stage, and improve the survival rate of seeds. With the continuous improvement of the degree of mechanization of agricultural production, the existing sowing equipment has been able to realize the integration and automation of sowing and fertilization, and manual fertilization has been gradually replaced by mechanical automatic fertilization. [0003] However, the existing automatic fertilization devices usually can only realize single-layer fertilization, that is, the fertilizer is stacked at a single depth and position in the soil. This method of fertilization will lead to uneven distribution of nutrients in the...

Problems solved by technology

[0003] However, the existing automatic fertilization devices usually can only achieve single-layer fertilization, that is, the fertilizer is piled at a single depth and position in the soil

This method of fertilization will lead to uneven distribution of nutrients in the soil, and the seeds may not be able to absorb enough nutrients due to deviation from the area where the fertilizer is located, affecting growth and development; it may also cause seedlings to burn due to being located in an area with too high a fertilizer concentration

Moreover, excessive concentration of fertilization will lead to low fertilizer utilization rate and waste of fertilizer, and the fertilizer remaining in the soil may also cause adverse consequences such as soil compaction, which will affect the replanting of crops
