Problems solved by technology

[0002] At present, traditional plant fertilization methods generally have many shortcomings such as slow fertilizer absorption, easy loss, cumbersome fertilization operations, high labor intensity, and inability to meet the three-dimensional needs of plants for fertilizers.
In addition, in the process of topdressing plants, it is necessary to frequently insert or pull out the topdressing pole from the soil, and due to the limitation of the structure design of the topdressing pole, it is very easy to cause only after fertilization of several plants and several times of plugging and unplugging. The topdressing rod is blocked, which greatly reduces the efficiency of fertilization

Abstract

The invention relates to a three-dimensional fertilizer placement drill. The three-dimensional fertilizer placement drill comprises a fertilizer placing rod (1), wherein the rod body of the fertilizer placing rod (1) is a cylindrical body in which an empty cavity (6) is formed; infiltration holes (5) are uniformly distributed in the side surface of the rod body; the infiltration holes (5) are distributed in the way that the maximum lengths of the infiltration holes (5) in transverse direction are reduced from the upper part of the rod body to the lower part of the rod body in the longitudinal direction. The three-dimensional fertilizer placement drill disclosed by the invention is simple in structure and convenient to use, the effect of three-dimensional fertilizing is realized, the fertilizing efficiency is greatly improved, the utilization ratio of a fertilizer is greatly increased, and besides, the fertilizer placing rod is prevented from being plugged.

Description

technical field [0001] The invention relates to a fertilizing tool, in particular to a three-dimensional top dressing device. Background technique [0002] At present, traditional plant fertilization methods generally have many shortcomings such as slow fertilizer absorption, easy loss, cumbersome fertilization operations, high labor intensity, and inability to meet the three-dimensional needs of plants for fertilizers. In addition, in the process of topdressing plants, it is necessary to frequently insert or pull out the topdressing pole from the soil, and due to the limitation of the structure design of the topdressing pole, it is very easy to cause only after fertilization of several plants and several times of plugging and unplugging. The topdressing rod is blocked, which greatly reduces the fertilization efficiency. Therefore, there is an urgent need to develop a fertilization tool that is reasonable in structure, easy to use, and helps to improve the utilization rate ...
