Street tree punching and fertilizing device capable of preventing tree roots from being damaged

Abstract

The invention relates to the technical field of fertilization, in particular to a street tree punching and fertilizing device capable of preventing tree roots from being damaged. The street tree punching and fertilizing device capable of preventing the tree roots from being damaged aims to solve the problem that a street tree root system fertilizer is non-uniformly absorbed or a root system is easily damaged during fertilization. The disclosed street tree punching and fertilizing device capable of preventing the tree roots from being damaged comprises a U-shaped punching and fertilizing machine with three supporting legs; the U-shaped punching and fertilizing machine is internally provided with four driving cavities which are in central symmetry by taking a tree as the center; the driving cavities are internally and rotatably provided with hollow rotating shafts which are through in the vertical direction; an electric push rod which is close to the ground side and communicated with the outside is fixedly installed in each hollow rotating shaft; and an electric push block is slidably arranged in each electric push rod.

Description

technical field [0001] The invention relates to the technical field of fertilization, in particular to a perforating and fertilizing device for street trees that can prevent damage to tree roots. Background technique [0002] Since the street trees are surrounded by hardened roads, the tree pools are small and the soil is compacted, it is difficult to apply traditional methods such as spreading, furrowing, and hole application, and the effect is not good. Punching fertilization is to apply compound fertilizer after punching four holes around the tree through punching equipment. Hole fertilization not only makes the fertilizer directly act on the root system of trees, which is conducive to the absorption of the root system, reduces waste, but also improves the permeability of the soil. However, the depth of roots of trees of different ages and sizes is different, while the depth of ordinary drilling is fixed, the root system absorbs fertilizer unevenly, and the effect is poo...
