The first step is to determine the amount of leaving buds. If the per mu yield is 2,000 kilograms, plant spacing is 2 meters and 3 meters according to 100 strains, the average strain yields 20 kilograms, according to 10 fruit counts per kilogram, each plant needs to retain 200 pieces of fruit, plus 20% of accidental loss, can stay Fruit 240; each fruit branch by 3 leaves fruit, you need 60 to 80 flower buds; winter cut by less leaving branches and more bud technology to trim, each mother branch by 6 to 8 flower buds trim, it takes 12 to 18 Mother branches, that is to say, can leave 2 to 3 mother branches per square meter.
The second step is to deal with the trunk. The first is to remove the trunks that are bent, wounded, stems and stems, and poor growth year by year in multi-trucks, but they cannot be removed too much at a time, so as not to affect the yield; the second is to carry out serious out-migration, aging, and weakness of the main culm. The third is the growth of the trunk is not ideal, can be cultivated and the use of the lower leggy branches to replace, wait for the new trunk after the fruit and then remove the old stem. The trunk branches that need to be removed should be sawed immediately after harvesting, so as not to cause wounds in spring wounds.
The third step, pruning, is to choose to leave the results of the mother tree. When choosing to stay in the mother branch, you can follow the principle of “five to five stayâ€: 1 go far to stay (light limbs away from the trunk); 2 go to stay (when there are several mother branches, choose to leave the next position) 3 to the outside (that is, peripheral branches, outside the two branches outside the graft) stay inside; 4 to bend (growth curl curved branches) stay straight; 5 to weak (weak branches, ultra short branches) stay strong; Cut off withered branches, dense branches, overlapping branches, and dry piles. When pruning, it is necessary to master the skills of “five-light and five-foldâ€: one-year-old trees are light and saplings are young; two young and big; and three are light and weak; and four are light and heavy; five are peripheral. Light and heavy. Select the remaining mother branches must be full of buds, maturity is good. At the same time, multiple selections should be made to leave 20% of the resulting mother branches to facilitate selection and comparison when cutting.
In the fourth step, the shoots are left to leave buds. After the pruning ends, the selected parental branches are treated. Generally, regardless of the spring and summer shoots, as long as they are full, all the buds are left to dry, and all the buds, sprouting buds, necrotic buds, and autumn shoots are cut off. The autumn shoots are from the blind spot. (ie topping) is cut off and the buds under the blindfold are generally of the best quality and should be preserved. According to the method of pruning and leaving a few buds, the long-resulting mother tree can retain 12 to 15 full shoots, the mediocre branch leaves 8 to 12 shoots, and the weaker branch to leave 6 to 8 shoots.
The fifth step, cut back. Select the remaining results of the mother branch to make appropriate comparisons, leaving enough to leave a good result of the mother branch, the inappropriate, unsatisfactory, missed and cut the weak branch again cut off.
The sixth step is to pull the twigs. After the end of pruning, branches are tied and the work is completed at the end of January of the following year. First, the branches are leveled on the surface of the rack with a hyperbolic cloth on the branches, pulled tightly around the outer wire, such as branches outside the heart of the empty tree can pull the branches tied. Each branch has 1 to 2 lanes, and branches should be evenly distributed. Http://Content/ddec2a28-58e2-4ea7-b6da-65898e621c44?cType=2
