Trimming technology
Determine the length of the mother branch: The length of the mother branch should be determined according to the variety, shaping method, scaffold size, and soil fertility. As the saplings expand the canopy, the mother branches can be left longer; the weaker trees and the older trees, in part, should be truncated. In terms of varieties, the short-fruit-branch varieties with high germination rates and short internodes, such as Huamei 2 and Kuimei, should be slightly heavier and shorter; while 93-01, Hayward and other varieties should be slightly lighter and shorter. According to the results of the mother-branch roughness and growth to determine the length of the cut, the strong results of the mother branch (greater than 0.8 cm in thickness, depending on the species, the same below) to retain 20 to 40 cm; thin results mother ( Coarseness less than 0.6 cm) 15 to 20 cm in length; less than 25 cm in length Mothers should generally be trimmed. The development branch generally leaves 8 to 15 buds short cuts; short-cut fruit branches should all be cut off. As a result, the arrangement spacing of the mother branches is preferably 30-40 cm.
Results Renewal of mother and fruiting branches: As a result, mother trees tend to languish after 1 to 2 years of results, or even die. The resulting parts generally cannot germinate. They can easily cause the relocation of the result parts or move upwards, weaken the tree potential, and lead to a reduction in yields. Fruit quality declines. Therefore, when the mother branch is updated, if the base has a robust or mature branch, it may be retracted to a robust site, or it may be cut off, replaced by a result branch or a development branch, or a short shear at the base of the latent bud, and then selected in the following year. A substantial new shoot is made as a result of the next year's mother branch. New shoots of kiwifruit that germinate from perennial shoots are generally incapable of fruiting in the current year, so the amount of renewal of the mother shoot should be 1/4 to 1/3. The resulting shoots are generally updated once or twice a year. The short-fruiting fruit varieties with weaker growth tend to require new or updated fruit trees each year; long fruit-tree varieties with strong growth potential, and the resulting fruit or fruiting branches. Updated once a year. The amount of shoots per plant is 600~800. When processing the resulting shoots, 2 to 6 bud positions can generally result, so 8 to 10 nodes are generally reserved, and the growth and development are particularly good, with a maximum of 15 nodes remaining, and the rest cut off. Short- and short-fruited branches are generally not pruned, and when the density is too dense, a portion is removed from the base. However, after the results, branches, short-fruiting branches and short-fruited fruit branches are senescent after the result and the axillary buds are weak, they should be cut off from the base.
Pruning of other branches: The development branch should be removed from the base in principle, but the habitat where the habitat is empty and there is a future for cultivation can be left for renewal and only the upper part of the thin and weak section can be cut off. Density branches should be sparsely cut, weak to stay strong, except for dense and thin, leaving as a result the mother branch should be cut off at the top of the unfilled part. In principle, cross-branches and overlap-branches should be divided by one, and the remaining branches should be removed from the tip of the weak part. However, if the cross-branches have good positions for both sides and are in neutral, they can all be retained and the intersecting parts can be cut off. Rolls that disturb the tree should be cut off. For branches with weak and weak branches, branches, stems and branches, and branches that do not grow well and have no growth potential, they should be cut off from the base.
Male winter pruning: The purpose of the winter pruning of male plants is to promote the supply of large amounts of pollen to female plants during the flowering period. Winter pruning is generally lighter, mainly by thinning dead and dead branches, twisting branches, pests and branches, overlapping branches and budding long branches; retaining all branches that grow and flourish, and lightly cutting them; Updated leggy branches and development branches; retracted perennial branches.
