Summer pruning method of wiping buds and picking hearts and cutting short branches of kiwifruit

Kiwifruit summer repair, in early August-early September. There are four main methods of pruning:

kiwi topping

Bud wiping: continue to wipe out all the excessive growth buds generated from the base of the kiwi fruit plant, especially on the rootstock, which have not been completely wiped out during spring germination; at the same time, during the winter pruning of the previous year, the new buds around the saw cut, the buds sprouting at the dense branches and leaves of the kiwi fruit tree, and all the axillary buds sprouting at the lower part of the first node of the growing branch in that year should be wiped out.

Topping: kiwi fruit in summer, strong growth potential, growth speed is very fast, growth volume is also very large, need to be picked a lot of branches and tendrils. It mainly includes: firstly, the excessive growth of the preparatory branches sprouted on the permanent branches can be picked at 80cm; secondly, the excessive growth of the fruit branches and long fruit branches can be picked at the 7- 8 leaves of the upper part of the last kiwi fruit; thirdly, the fruit mother branches and development branches with strong growth potential should be picked under different conditions. Generally speaking, the second branch leaves 3--4 leaves after picking, the third branch leaves 2--3 leaves after picking.

Truncation: kiwifruit pruning in summer, under normal circumstances, very few of the branches are truncated. However, the excessive fruit branches and long fruit branches omitted during the pinching should be truncated at the 7- 8 leaves above the fruit position; at the same time, the excessive vegetative branches with heavy light shielding can also be appropriately truncated.

Thinning branches: kiwifruit summer thinning branches, mainly thinning out all excessive long branches sprouted from the base, some excessive long sexual branches sprouted from the permanent main vine and all diseased branches; properly thinning out over-dense branches, weak branches, mechanical damage branches and temporary female branches sprouting part of the fruit branches. In addition, it should also be appropriate to eliminate excessive fruit, weak growth potential, or obstacles to ventilation and light transmission, extension of the ground under the back of the fruit branches, etc. Summer thinning time should be early, generally in the shoot length of 30--40 cm should be carried out.
