Fertilizer application device applied to film-covering planting

Abstract

The invention relates to a fertilizer application device applied to film-covering planting. The fertilizer application device comprises a feed hopper, a fertilizer application pipe, an operation unit and a spike part used for inserting into soil; the fertilizer application pipe is a circular pipe with a cavity; the feed hopper has a funnel-shaped structure and is arranged on the top of the fertilizer application pipe; the spike part is arranged at the bottom of the fertilizer application pipe, is connected with the operation unit and is composed of a first insertion sheet and a second insertion sheet which are in bilateral symmetry; and a cavity body is formed between the first insertion sheet and the second insertion sheet, and an opening or closing state between the first insertion sheet and the second insertion sheet is realized under the action of the operation unit. The fertilizer application device is simple in structure and convenient to use, lightens work strength, avoids artificial large-area fertilizer application, is accurate in fertilizer application position with good fertilizer application effect and is particularly suitable for fertilizer application to film-covering crops with shallow root systems.

Description

technical field [0001] The invention belongs to the technical field of fertilizing equipment in the field of crop planting, and in particular relates to a fertilizing device applied to film-covered planting. Background technique [0002] As we all know, adding fertilizers to the soil can supplement the nutrients needed for growth and development of crops, thereby improving the quality and yield of crops. At present, the level of agricultural mechanization in our country has become higher and higher, and the application of fertilization machinery has become more and more extensive. However, the current fertilization machinery is large-scale. The use of mechanized fertilization has little effect on crops with high plant density, but For crops with large plant spacing, this fertilization method can not effectively concentrate the fertilizer near the roots of the crops, resulting in a large amount of waste of fertilizer, which not only reduces the fertilizer efficiency but also ...

Problems solved by technology

Of course, in order to achieve precise fertilization, specific fertilization equipment is required to apply fertilizer accurately. For film-mulched planting, precision fertilization technology can not only improve its quality and yield, but also cannot increase the economic income of growers.
