The primary purpose of tree pruning in full fruit stage is to maintain the prominent skeleton structure of the tree, keep the balance between the aboveground and underground parts, vegetative growth and reproductive growth, maintain strong sustainable fruit-bearing ability when the tree is strong, and prolong its economic life. Kiwifruit has strong growth potential, long branches and leaves, and is easy to sprout. After plastic surgery, the relationship between growth and fruiting should be adjusted by pruning every year to keep the plants strong and vigorous.

Pruning kiwifruit is relatively complicated and requires certain technical content. Many fruit farmers always go into a misunderstanding when pruning, which leads to poor pruning effect. The pruning degree of kiwi fruit tree should be determined according to the variety, growth and other factors. If you prune blindly, it will affect the growth and yield of fruit trees. Summer pruning time is generally after kiwifruit begins to swell, which is also the prosperous period of kiwifruit bearing branches. The approximate time is from mid-May to early July.

Results The pruning of mother branches depends on the growth of branches. Overgrown fruiting branches should leave 6-7 buds above the fruiting parts. Long, medium and short fruiting branches leave 4-6 buds above the fruiting position. As a result, it is not easy to keep too many mother branches. 2. Pruning of vegetative branches. Vegetative branches also become growth branches and development branches. Pruning is generally carried out according to the growth of branches. For vegetative branches with a length of about one meter, cut off moderate fruiting branches with a length of 60-75cm and 50-80cm, and cut off slender branches with a length of 40-60cm and less than 50cm.

For branches that are enough to bear fruit in the next year except the mother branch, leave two or three leaves upward from the bud to be pointed. Maintaining this tree is equivalent to completing the annual summer pruning? When cutting leaves in winter, the workload is also very small! The pruning time of kiwifruit in winter should start from 7~ 10 days after the leaves of fruit trees fall. This time period refers to the period from mid-June, 65438+February to 1 end of each year, and it can also be pruned for 7~ 10 days after defoliation. Early pruning can make the wound dehydrate and shrink as soon as possible, and reduce the amount of bleeding in the next spring. Pruning methods vary with varieties and tree potential. The basic principle is to remove this year's fruiting branches and leave the vegetative branches.
