Description

Convenient and safe Girding cutter

Technical field

The present invention relates to a kind of plant cultivation instrument, particularly a kind of convenient and safe Girding cutter.

Background technology

Band girdle is ringing, also cries girdling, tree bar is peelled off to a circle skin.People, when the fruit trees such as cultivation jujube tree, orange tree, often need to carry out band girdle to mobile jib, stop nutrient to come downwards to tree root, to promote the fruit on trunk to obtain more nutrient component, make fruit output high, quality better.Carrying out at present at present band girdle is mainly to cut out or saw out twice fracture port on the skin of tree bar, then uses the shovels such as knife to fall the bark between twice fracture port, reaches the object of band girdle.Although this band girdle mode also can reach the object of band girdle, there is following problem in it:

1. cannot the fine controlled fracturing blasting mouth degree of depth, often, because too dark and damage tree bar, affect trees to produce, particularly prop up the jujube tree very little in those bars, to cut a little or saw more deeply, a bar that will badly damaged jujube tree, even makes trees lethal; Also likely cut or saw too shallowly, shovel again pretty troublesome below, because bark is fracture completely not, sometimes because involve, shovel a sheet of bark, have a strong impact on trees and produce even life, very inconvenient while making to shovel skin, sometimes also need again to carry out cutting or sawing at fracture port place, so that bark ruptures completely;

2. on the skin of tree bar, go out after twice fracture port, need to use other instrument (being generally knife), again the bark between twice fracture port is shoveled, and can not with cutting or shovel skin during sawed-off breach simultaneously, two procedures is completely independent, wastes time and energy.

At present, also occurred some Girding cutters, it more than same existence two problems: the bad adjusting of the degree of depth of the fracture port of cutting, easily damages trees; Cannot in cutting twice fracture port, shovel the bark that needs band girdle to fall between twice fracture port.

Summary of the invention

The object of the invention is to overcome the above-mentioned deficiency of prior art and a kind of convenient and safe Girding cutter is provided; It is safe and reliable, and the degree of depth of the fracture port cutting out is adjustable, can not hurt tree bar or damage trees, can cut off again bark simultaneously completely, without operation repeatedly; It can shovel the bark of middle band girdle when cutting twice fracture port, and the disposable band girdle that completes operates, time saving and energy saving, rapidly and efficiently.
