Problems solved by technology

[0003] Problems in the current pruning method: there is no standard, pruning according to experience, and the pruning effect is inconsistent; leggy branches still exist, consume nutrients, and affect the monomer size and quality of kiwi fruit. The general yield per mu is 1200-1600 kg

Embodiment 1

[0013] The pruning method of kiwifruit trees is aimed at Northwest Hubei, specifically:

[0014] (1) At the end of January, keep only 4 main branches on the main trunk of the kiwifruit tree, and trim off the remaining branches and branches; keep 6 buds on the main branches, and trim off the rest; wrap and tie the pruning wound with plastic film Bind to avoid frostbite; Climb the 4 main branches on the scaffold;

[0015] (2) In the first ten days of April, the main branch grows fresh branches from the buds, keep 4 strong branches as the fruiting mother branches, and trim off the remaining fresh branches;

[0016] (3) In late June, cut the tip and keep the length of the fruiting mother branch at 150 cm;

[0017] (4) In late August, prune off the elongated and drooping branches on the fruiting mother branches, prune off the over-dense branches of the fruiting mother branches, improve ventilation and lighting, and ensure the nutrient absorption of the fruiting mother branches.

Embodiment 2

[0019] The pruning method of kiwifruit tree is aimed at Northwest Hubei, and embodiment 1 is specifically in the same environment and soil plots:

[0020] (1) At the end of February, keep only 3 main branches on the main trunk of the kiwifruit tree, and trim off the remaining branches and branches; keep 5 buds on the main branches, and trim off the rest; wrap and tie the pruning wound with plastic film , to avoid frostbite; attach the 3 main branches to the trellis;

[0021] (2) In the first ten days of April, the main branch grows fresh branches from the buds, and 3 strong branches are kept as the fruiting mother branches, and the remaining fresh branches are trimmed off;

[0022] (3) In late June, cut the tip and keep the length of the fruiting mother branch at 120 cm;

[0023] (4) In late August, prune off the elongated and drooping branches on the fruiting mother branches, prune off the over-dense branches of the fruiting mother branches, improve ventilation and lighting,...

Abstract

The invention provides a pruning method of kiwifruit trees and aims to provide a standard pruning method to ensure uniformity in individual size and quality of kiwifruit fruits and increase yield permu. The pruning method includes: from January to February, only retaining 2-4 main branches and tendrils on trunks of the kiwifruit trees, and pruning other branches and tendrils and twigs; retaining5-6 buds on the main branches and tendrils, and pruning other parts; using plastic thin films to wrap and bind pruning wounds to avoid frostbite; enabling the 2-4 main branches and tendrils to climb onto a canopy frame; from late March to early April, when fresh twigs grow out from the buds of the main branches and tendrils, retaining 3-4 strong twigs as twigs of bearing shoot, and pruning other fresh twigs; from late May to late June, only retaining the twigs of bearing shoot of 120-150cm in length; from late July to late August, pruning water shoot and droopy branches on the twigs of bearingshoot, and pruning overcrowded branches of the twigs of bearing shoot to improve ventilation and daylighting so as to ensure nutritional absorption of the twigs of bearing shoot.

Description

technical field [0001] The invention belongs to the cultivation field of kiwifruit trees, and relates to a pruning method of kiwifruit trees. Background technique [0002] In the cultivation and management of kiwifruit, pruning branches is the key to the yield and quality of kiwifruit. The current known technology generally combines winter pruning and summer pruning: the main content of winter pruning is thinning and short cutting; It should be 3 cm above the buds; for elongated branches, generally keep 5-6 buds and cut them short, promote 2-3 branches, and remove them as soon as possible when not needed; for long fruit branches and medium fruit branches, keep 2-3 Buds; for short fruit branches and shortened fruit branches, generally do not cut short; summer pruning: deal with elongated branches and drooping branches, and remove over-dense branches. [0003] Problems in the current pruning method: there is no standard, pruning according to experience, and the pruning effec...
