The technology of reflective film has been paid more and more attention in the development of society. It is also widely used. It is not only used in the transportation industry, but also in the apple orchard laying. It has high practical value in the fruit tree production. The productivity and efficiency of fruit trees were increased. The principle of using the reflective film technology in the apple orchard is to reflect the sunlight through the reflective film, and improve the illumination conditions of the whole orchard, especially the lower and inner bore of the tree, so that the fruits of these parts, especially the parts of the fruit which are not easy to be coloured, are fully colored. This is the most important point.
Several problems should be noticed in the process of laying reflective film. Along the tree row, lay on both sides of the canopy, the outer side of the reflective film is on the outer edge of the crown. When laying, the reflective film is put on one end of the orchard, and then the film is rolled back slowly, and the edge is rolled out with stone, brick or rope, and the stick of the bracing technique can be lifted and pressed on the film. Film should not use soil, to prevent the reflection face dirty influence reflective effect. Should be careful not to pierce the membrane film.
Paving time. Bagging orchard is usually carried out 3-5 days after the fruit bag is removed, and the orchard without bagging is suitable for 30-40 days before harvest. Shaanxi Guanzhong and Weibei plateau orchards usually start in the middle of 8 or early September.
Preparations should be done well, and preparations should be made several days before laying. The arbor orchards can clear trees and rows of weeds in front of the paving and leveling the ground with rakes, and the conditional orchard can also be made into a small slope with high and low levels in a row in order to prevent the effect of water accumulation. The dwarf garden can be covered with the terrain. Bagging orchards should first remove bags and lay leaves properly before laying. In order to ensure the effect of the film, it can also trim and retract the trailing skirt branches in the lower crown of the tree and remove the long branches with heavy shading in the crown of the tree, so that more sunlight will be projected onto the reflective film.
In order to achieve better results, the film should be combined with other management techniques such as fruit bagging, leaf picking and turning, in order to increase full red fruit and produce high quality apples. In order to improve the efficiency of reflective film, do not stack litter, rotten leaves and sundries on the membrane. Pay attention to cleaning up the rotten fruit, dust and branches and leaves in time. After the membrane is rotted, the membrane will be recovered and destroyed, and it will not pollute the soil.
