The growth of kiwifruit vines is strong. Through winter cutting, the tree branches can be distributed reasonably, and their ventilation and light transmission conditions can be improved, which can reduce the ineffective nutrient consumption, which is conducive to high yield and high quality.
Time standard
Kiwi winter cut should be carried out from late December to mid-February.
Target
Mainly rational and moderate trimming of the resulting mother twigs of kiwifruit, comprehensive removal of dead branches, thin and weak branches, diseased shoots, overlapping branches, rootless buds with no use value, and developmental branches without cultivation prospects.
Location criteria
For the shearing of the various types of mother trees, it is necessary to determine the amount of shoots and the length of shoots based on the strength of the branches. Generally, for the result branch with leggy, 4 to 5 buds should be cut at the result site. For long branch, 3 to 4 buds should be cut above the result site. For short branch, 1 to 2 buds should be cut above the result site. Or not trim. Mothers who have been senescent or have a continuous result for more than 3 years should be pruned. If the resulting mother shoots are weak or the branches are too high, they should be cut off from the part of the base where there are latent shoots. The cut-off part should be placed on the shoot at 3 cm to promote its germination. Perennial perennial shoots are trimmed and the local or whole plant regeneration is taken according to their ageing sites.
