First, trim the young trees.
Kiwifruit also needs proper pruning in the young tree stage, and the main pruning direction in the young tree stage is to give priority to mother branches and cultivate main branches. Therefore, everyone should cut off the new buds of the rootstock and wipe off the extra buds in time during the growth period of young kiwifruit trees. When the fruiting branch grows to about 70 cm, the coring work should be done in time.
Second, pruning during the growth period.
Pruning should not be too heavy during the growth period, and the branches that are too dense should be cut off, and the fruiting mother branches and vegetative branches on kiwifruit trees should be distributed reasonably. During the growth period, when the vegetative branches grow to about 70 cm, they are also picked. In this way, the fruit node at the top of the branch can retain about 6 leaves for core removal. After entering the dormant period, the new buds that grew in that year should be cut short.
Third, pruning at full fruit stage.
Pruning intensity should be controlled according to kiwi fruit tree potential in full fruit stage. For example, the pruning intensity should be increased for kiwifruit trees with weak growth, and the pruning intensity can be appropriately reduced for those with strong growth. Strong branches can stay long when they are cored.
Fourth, dormant pruning
After the temperature drops in winter, kiwi fruit tree will also go into hibernation. At this time, everyone can adjust the pruning method mainly according to the kiwifruit variety. For example, China kiwi can keep seven to nine buds on strong and nutritious branches.
Precautions for pruning
1 because trees are pruned.
You can pay attention to kiwi fruit tree's growth years, variety characteristics and other aspects during the pruning process on weekdays. Many fruit farmers don't pay attention to these things, and blindly pruning has caused the situation of trees growing in big and small years.
2. Winter cutting time
I believe everyone is familiar with winter pruning. Many fruit farmers will do it immediately after harvest, but they will not trim it well just after harvest, which will waste a lot of nutrients. It is suggested that winter pruning should be carried out about ten days after defoliation.
3, processing pruning branches
Remember to cut off dead branches and branches of pests and diseases in time, otherwise it will easily become the source of infection in the coming year.
Step 4 cut decisively
Many novice growers are reluctant to prune some branches that look healthy. In fact, this will cause kiwi fruit tree to grow vigorously and its branches and leaves will be in chaos.
5, pay attention to cut the mouth buds
On weekdays, everyone should pay attention to the situation of cutting buds and make short cuts according to factors such as varieties and growth.
