Does kiwi fruit need to be cut if it wants to grow? How to prune?

Pruning time: 15 days after the leaves fall to 15 days before the sap flows in early spring.

Pruning objects:

①For saplings planted in the current year, first leave three full buds at the base of the plant, then select the strongest branches as the main trunk, and implement light pruning. Allowing it to rapidly expand its canopy every year.

②A tree that enters the juvenile stage after one year of growth. Try to make the fruiting vines on the main vine evenly distributed on the shelf, and expand the proportion of the fruiting vines on the basis of promoting the growth of the main vine, lateral vines and fruiting mother vines.

③Adult tree. Pruning should be light, and the fruiting vines should be cut short, leaving 4 to 5 buds at the cutting edge. For leggy vines, 4 to 5 buds should be left to allow 2 to 4 new shoots to sprout; for general vegetative vines that grow robustly, Cut off 1/3 or 1/2 of the full length to transform it into a fruit-bearing vine; leave 8 to 10 short buds for medium-length fruit vines and overlapping cross vines, and leave 5 to 6 buds for medium fruit-bearing vines. The weaker ones leave 3 to 4 buds.

④ Plants that are old and weak. Implement branch and vine renewal points to retain the fully grown fruiting vines at the base of the mother vine, which can be retracted to the strong part. If the mother vine is too weak, it should be cut off from the place where there are latent buds at the base, so that the latent buds can sprout strong new shoots.

Post-pruning treatment: No matter what kind of implant, after pruning, a callus anti-corrosion film should be applied to the cut edge in time to promote the wound to heal as soon as possible, prevent the invasion and replication of bacterial infection, and keep it warm and cold; The dead branches, twigs and rotten leaves should be cleaned up and burned in a timely manner, and the garden should be thoroughly cleaned, plowed deeply to dry out moisture, and fertilized with water. This can effectively kill overwintering pests and diseases and greatly reduce the number of overwintering pests and diseases. A new high-lipid film should be sprayed to keep warm and cold-proof, and prevent the migration of pests and diseases. Invasion; all trees in the park must be painted with tree protector to prevent freezing, suffocation and sterilization, prevent and treat various cortical diseases, and ensure safe wintering.
