Device for preventing trunk of actinidia arguta fruit tree from slow sunshine freezing

Abstract

The invention discloses a device for preventing a trunk of an actinidia arguta fruit tree from slow sunshine freezing. The device for preventing the trunk of the actinidia arguta fruit tree from slow sunshine freezing comprises a fixed seat, a positioning pin, a first protective cover, a second protective cover, a fixed column and a protective cover, wherein a through hole is formed in the middle of the fixed seat, the positioning pin is vertically fixed to the bottom wall of the fixed seat, the first protective cover and the second protective cover are both of semi-cylindrical structures, are symmetrically arranged and are fixed on the top of the fixed seat; each of the first protective cover and the second protective cover comprises a fixed cover body, a heat preservation cotton layer and a medicament sheet layer, wherein the fixed cover body is of a hollow structure, air holes are further formed in the inner side wall of the fixed cover body, the heat preservation cotton layer and the medicament sheet layer are sequentially arranged in the fixed cover body from outside to inside, the protective cover is fixed to the top side wall of the fixed cover body, and arc-shaped rubber rings are fixed to the opposite side walls of the two protective covers. The device for preventing the trunk of the actinidia arguta fruit tree from slow sunshine freezing is simple in structure, reasonable in design, convenient to install, good in anti-freezing effect, long in service life, good in structural stability and capable of effectively preventing the fruit tree from diseases and insect pests, and has good market application prospects.

Description

technical field [0001] The invention relates to the technical field of antifreezing of trees, and more specifically relates to a device for preventing slow freezing of the trunk of a jujube kiwi fruit tree. Background technique [0002] The kiwi fruit trees planted in the three northeastern provinces of my country have a large change in temperature between day and night in early spring, and one freeze and one thaw can easily cause the trunk and roots of the fruit tree to suffer from freezing damage, commonly known as slow sun freezing, which seriously affects the normal growth of the fruit tree. [0003] Most of the existing technical methods for preventing slow sun freezing of fruit tree trunks are to use whitening liquid to artificially whiten the trunk. However, there are many shortcomings in this method. Also can fall off naturally afterwards, and protective effect is bad, needs frequent brushing, has improved the labor intensity of the staff, the 2nd, because the unifor...

Problems solved by technology

[0003] Most of the existing technical methods for preventing slow sun freezing of fruit tree trunks are to use whitening liquid to artificially whiten the trunk. However, there are many shortcomings in this method. Afterwards, it will fall off naturally, the protective effect is not good, and it needs to be painted frequently, which increases the labor intensity of the staff. Second, due to the uniformity and uneven thickness of the artificial paint, the degree of damage to the local trunk is exacerbated.

In the prior art, there is also a method of binding hemp rope or straw to protect the tree trunk from slow sun freezing, but the service life of the hemp rope is short, and it is extremely inconvenient to bind. The friction to the bark is relatively large during the binding process, and the use performance is not good. However, the use of straw not only causes great friction to the bark, but also tends to harbor insects, causing insect damage to the trunk, and the use effect is not good.
