Citrus reserved tree preservative film fixing equipment and preservative film fixing method

Abstract

The invention discloses citrus reserved tree preservative film fixing equipment and a preservative film fixing method, and relates to the field of crop equipment. A plurality of uniformly-arranged fixed holes are formed in the edge of a preservative film, the equipment comprises a plurality of fixed rods and a plurality of metal rings, the outer walls of the metal rings are fixedly connected withthe inner walls of the fixed holes, a plurality of grooves are uniformly formed in the side face of each fixed rod in the vertical direction, a pair of straight leaf springs is arranged in each groove, the upper end of each upper straight leaf spring is fixedly connected with the upper inner wall of the corresponding groove, the lower end of each upper straight leaf spring extends towards the upper end of the corresponding lower straight leaf spring, the lower end of each lower straight leaf spring is fixedly connected with the lower inner wall of the corresponding groove, the size of a gap between the lower end of each upper straight leaf spring and the upper end of the corresponding lower straight leaf spring is smaller than the thickness of the corresponding metal ring, and each metal ring penetrates through the position between the lower end of the corresponding upper straight leaf spring and the upper end of the corresponding lower straight leaf spring and sleeves the corresponding fixed rod. The preservative film is not prone to damage at the fixed holes, the distance between the preservative film and the ground can be adjusted, and then the ventilation effect in the preservative film coverage area is guaranteed.

Description

technical field [0001] The invention relates to the field of keeping freshness of citrus trees, in particular to a fixing device and method for fixing a fresh-keeping film of citrus trees. 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...
