First, sapling pruning
1. In the first year after fixed colonization, the stems were generally not cut and dried, and their branches were naturally smoked. In the second year, stems and stems were selected according to the characteristics of the varieties and the growth of shoots.
2. In the pruning of the main stem and the main lateral branch, the dry growth is generally strong. To prevent excessive growth, one quarter or one third of the full length should be cut off and the strong buds should be removed. When the middle reaches the second level, it should be picked up in the summer or short in the winter to promote strong branches as the second main branch. The main lateral branch is generally not short-cut, in order to balance the growth of the stem branches, and the main branch can be cut off to reduce the growth potential. After the start of the results, in order to trigger branching and prevent the relocation of the resulting site, the strong shoots can be left short for about 30 cm. According to the specific circumstances, the short branches of the branches other than the backbone branches may be appropriately removed to remove the overlapped branches, crossovers, densely crowded branches, and the inner branches of the internal malleolus, so as to facilitate the ventilation and light transmission; the short part of the moderate development branches and weak branches may be promoted. Birth branches, cultivating the result branches.
Second, full fruit trim
1. Results The pruning of branches of persimmon trees was dominated by the results of strong branching. As a result, the thicker the branches were, the more the number of branches resulting from pumping, and the more the number of fruit set, the more attention should be paid. As a result, when the branches are gathered together, they should be thinned and cut to stay strong and keep a certain distance. Excessive results can be shortened as a branch. For the dense gardening results, in addition to properly sparsely detaching some of the crops, they should also be shortened to a suitable degree so that the results can be cultivated in the coming year, and the size of the crops can be prevented. The fruit setting rate is high, and the fruit quality is good. If the branch has a good development branch or falling fruit branches, can be updated downwards year by year.
2. The pruning of the development branches will sparse the weak development branches on the inner or large branches to facilitate ventilation and lightening and reduce the nutrient consumption. For robust development branches, if there is space for the appropriate sites, they can be appropriately short-cut (leave 20-30 Centimeter) to promote branching, cultivating branches and groups; the developmental branches of the golden mean can easily be transformed into the result garden branches, which can be dumped without cutting.
3. The pruning of the renewed branches is not suitable for those who have had excessive refitting of the old ones, and should generally be modified and utilized, and there are plans for the purpose of triggering renewals. The transformation method is generally suitable for its short cuts, and promotes the pumping results. In addition, for a part of the biennial branches, the growth of weak branches and dense crowded branches, cross branches, cluster branches, and dead branches of pests and diseases should be removed to facilitate ventilation.
4. After the adjustment of the skeleton branch, the backbone branches after the peak period, the front end is easily sagging. For large branches with sagging bends, new branches with vigorous vitality can often be produced in the curved part, and the sagging part can be retracted to raise the angle, but it cannot be retracted too much at a time.
Third, the renewal of the pruning tree during the aging period is extremely weak, the dry branches increase year by year, only flowering without fruiting, when the yield is extremely low, it should be updated and rejuvenated, promote its re-establishment of the tree canopy, restore the tree vigor, and extend the results of years.
1. The rotation is updated in all main branches of the tree. Each year, some large branches are retracted and completed in 2-4 years. Generally in the 5-7 years left to branch retracted 8-10 cm thick site saw off, first upright erection branches, after shrinking horizontal branches.
2. In one year, the whole tree renewal saw the main branches of the whole tree sawn off in the 5-7 years old part of the tree. The new branch was stabbed, the buds and branches were promptly wiped in summer, and new parts were cultivated.
Fourth, summer trim
1. After retraction of the large shoots of the bud, the scallops often appear with clusters of branches, leaving 1-2 to be cultured and the rest wiped off. In addition, budding shoots are often generated at the branches of coarse branches. Except for a few fills, the rest Also erased.
2. Topping up the useless leggy branches, when it reaches 20-30 centimeters, picking up the heart, controlling the growth, and promoting secondary branches. In the fall, most of the secondary branches can form flower buds and become the result garden branches. For renewal of new shoots that have been pruned and trimmed, they can be plucked at the appropriate sites to promote the occurrence of secondary and tertiary shoots, allowing them to form crowns as soon as possible.
3. Flowering saplings of sturdy young trees or persimmon trees that are not easy to grow, and girdling during flowering can promote flower bud differentiation. Early results, especially to prevent physiological fruit drop, are very effective. The method is: using a knife to cut the bark on the trunk or branch 0.5 centimeters wide, the incision is a circular or spiral shape with double abundances and misalignment.
