Device for retaining freshness of oranges on trees

Abstract

The invention discloses a device for retaining freshness of oranges on trees. The device comprises a protective film and a plurality of supporting rods, wherein the protective film is used for covering a plurality of orange trees, the orange trees are uniformly arranged and comprise M lines of orange trees, each line comprises N orange trees, the (n-1)th orange tree and the nth orange tree of the(m-1) line and the (n-1)th orange tree and the nth orange tree of the m line are four orange trees corresponding to a first quadrangle, the crown vertexes of the four orange trees covered by the protective film are four vertexes of the first quadrangle respectively, each first quadrangle corresponds to one supporting rod, the lower ends of the supporting rods are fixed on the ground, and the upperends of the supporting rods support the lower surface of the protective film corresponding to the area where the first quadrangles are located. According to the device, large-area accumulated water formed in a low-lying area of the protective film of the fruit trees is divided into a plurality of small-area accumulated water and supported, so that damage to the fruit trees and the protective filmis prevented.

Description

technical field [0001] The invention relates to the field of agricultural equipment, in particular to a citrus tree preservation device. Background technique [0002] Citrus, as an important economic crop in the southwestern countryside, is planted on a large scale in Yunnan, Guizhou and Sichuan in the southwest. The varieties include various oranges, such as Chunjian (also known as Papaan), Shiranui and so on. For a better price, many fruit growers will keep the fruit until the Spring Festival to start selling, and even in some areas, they will choose the season with less fruit after the year to harvest and sell the fruit in order to increase profits. However, the twelfth lunar month is often the time of the year when the temperature is the lowest, so when fruit farmers keep trees fresh, they need to take certain cold protection measures to ensure the safe wintering of fruit trees. [0003] In the prior art, existing cold-proof measures mainly cover cold-proof cloth. Exis...

Problems solved by technology

[0006] In order to overcome the technical problems described in the background technology, that is, in order to solve the problem that a large area of ​​water will be formed in the low-lying area of ​​the fruit tree protective film, the present invention provides a citrus tree preservation device, the device in the present invention is installed under the protective film There are support rods, which decompose the original large low-lying area into several smaller low-lying areas. The force of each low-lying area is smaller than that of the original one. With the support of the support rod, the damage to the fruit trees and protective film is effectively prevented.
