First, the purpose of autumn shears is to increase the light, increase the light transmittance of the canopy, and promote the coloration of the fruit, mainly to eliminate the long branches, the competition branches, the erect branches, so that the leaves of each branch are evenly illuminated to ensure the coloration of the fruit. . Second, the leaves are removed to remove the leaves at the base of the fruit table. The leaves from the base of the new shoots near the fruit can be removed appropriately to increase the direct bathing degree of the fruit, effectively enhance the coloration, and prevent the leaf surface from adhering to the fruit surface and making the fruit Forming a spot. The leaf picking is generally carried out twice. The first time the combined removal of the inner bag of the fruit is carried out to remove the leaflets around the fruit. The second leaf picking is carried out one week after the first leaf picking, and all the fruits can be removed. Shading leaves. The test results show that with the increase of the amount of leaf picking, the ratio of whole red fruits also increases, but the more leaves are picked, the better. With the increase of leaf picking, the daily burning phenomenon is more and more serious, suitable for picking leaves. The amount should be 15% to 20% of the whole tree. Third, the fruit transfer and fruit transfer fruit and fruit can increase the fruit coloration index by an average of about 20%. During the fruit-transfer period, the bag is removed for about 15 days (that is, after the foot color on the sun surface), and the shade of the fruit is turned to the sunny side by changing the position of the shoots and the direction of the fruit. (To prevent the fruit from returning to the original position, the fruit can be peeled off with transparent white tape. Fixed) to make it fully exposed to light. Gently turn the fruit handle when changing the fruit to avoid spraining the fruit and leaving the layer, causing fruit drop. The time of fruit transfer is controlled before 10 am and after 4 pm to prevent sunburn. The mat is mainly used to prevent the branches and leaves from being damaged after the fruit is removed from the bag. The removed paper bag is used to pad the fruit surface close to the branches. This prevents the fruit surface from being scratched by the wind and affects the appearance quality of the fruit. Fourth, the silver reflective film in the fruit coloring period (red Fuji apples in early September), the tree plated silver reflective film can improve the inside of the canopy and the lower light, so that the lower part of the crown, especially the fruit and surrounding Fully colored, truly achieve full red fruit, while increasing the sugar content of the fruit. The reflective film is placed under the canopy, leaving a working path between the rows, and the edge is fixed. The film for each acre orchard is 400-500 square meters. The reflective film will be collected 1 to 2 days before fruit harvesting, washed, dried, and used in the second year. The range of laying is limited to the vertical projection of the canopy. V. Pest Control After the bag is picked up, in order to prevent the rotten fruit disease caused by latent bacteria in the fruit, a systemic fungicide should be sprayed once.
