Quantitative fertilization tool for agricultural planting and use method thereof

Abstract

The invention relates to the technical field of fertilization tools, in particular to a quantitative fertilization tool for agricultural planting and a use method thereof. The quantitative fertilization tool comprises an outer pipe, the bottom end of the outer pipe is fixedly connected with a puncture part, the inner side wall of the top end of the outer pipe is fixedly connected with a cover plate, and the portion, located below the cover plate, of the inner side wall of the top end of the outer pipe is fixedly connected with a first limiting plate; a square rod penetrating through the cover plate and the first limiting plate is arranged in the outer pipe, the square rod is slidably connected with the cover plate and the first limiting plate, and a round rod is fixedly connected to the bottom end of the square rod. According to the quantitative fertilization tool, through the arrangement of a puncture head and a puncture part, a handle is pressed down, the puncture head and the puncture part are punctured into the land, a support ring is treaded, the handle is pulled upwards, the puncture head is retracted into the puncture part, the bottom end of the puncture part is released, and the fertilizer in a quantitative adjustment mechanism falls down, so that the fertilizer is applied. The fertilizer can completely enter the soil, and waste is avoided; meanwhile, the puncture part and the puncture head are arranged in a three-edged thorn shape, so that the tool is more convenient and labor-saving to puncture into soil.

Description

technical field

[0001] The invention relates to the technical field of fertilization tools, in particular to a quantitative fertilization tool for agricultural planting and a use method thereof. Background technique

[0002] Although the current degree of agricultural mechanization is relatively high, when fertilizing irregularly shaped fields or fields with large undulating terrain, it is still necessary to rely on manual fertilization. Fertilization is mainly divided into three steps: digging holes, spreading fertilizers, and covering soil.

[0003] Most of the existing fertilization tools use a conical head to pierce a circular hole on the ground, and open a hole on the side wall of the conical head, so that the fertilizer enters the pit through the side hole to complete fertilization. The side hole is easy to block when it penetrates into the soil. There is also a method of inserting the drill rod into the soil obliquely, and then "opening" the pit to sprinkle fertilizer...
