Grasp the time to wipe buds. The sprout time of the kiwi fruit tree should be carried out when the quality of the bud can be clearly identified. If the buds are wiped too early, the quality of the buds cannot be confirmed. If the buds are wiped too late, the nutrients will be ineffective and excessive consumption. Generally, the buds are wiped off when 80% of the buds in the crown grow to 3 cm to 5 cm.
Grasp the object to be erased. Generally, the objects to be erased are buds under the back, weak buds, deformed buds, and buds without or few buds. For opposite buds, whorl buds, cluster buds, adjacent buds, dense buds, etc., you can choose to leave 1 bud. Erase the vegetative branches at the top of the fruiting mother branch, and the extra long buds on the main vine or in the inner chamber.
Grasp the sprout method. For kiwi trees of different ages, the method of spraying buds will be different. Generally, for mature kiwifruit trees that bear fruit, the strong fruiting mother branch can remove the redundant dense and weak buds and each branch leaves 10-12 buds, the moderate fruiting mother branch leaves 8-10 buds, and the weak fruiting mother branch leaves 4 ～6 buds, 2～4 buds for weak short branches, 1～2 buds as buds. Follow the principles of removing the next (down on the back) and staying on the top (up on the back), removing the weak and staying strong, and removing the dense and thin.
In wiping buds, we should pay attention to three requirements:
1. It should be noted that in the case of cold spring and disease and insect pests, it cannot be erased at one time, and a certain amount of leeway needs to be left, at least 20% reserved.
2. The latent buds on the main vines at the base of the inner chamber and the result mother branches germinate late, and these parts need to be cultivated to renew the reserve branches, so it is not recommended to wipe the buds, and then choose to wipe them when they germinate into young branches.
3. Due to the formation of the climate or the size of the year, the mother branches have more vegetative branches. Except for the dense and weak branches, all the others are retained to ensure the normal growth of the tree.
