How to determine the latest kiwifruit winter cutting time

Kiwi planting is very common in China, and now with the gradual decrease of temperature, it has entered winter. And after winter, kiwifruit winter shearing work is very important. The success of winter pruning will gradually affect the yield of kiwifruit in the coming year, so it needs everyone's attention. So how to determine the winter cutting time of kiwi fruit? The following small series will give you a brief introduction. Let's take a look together!

1. Winter shear time

When pruning kiwifruit in winter, we should first pay attention to the time. It should start about half a month after the fruit trees fall, usually in mid-December and continue until the beginning of spring the following year. It is best to do it three weeks before and after the winter solstice. Time is very important, not too early or too late. If the pruning time is too early, the nutrients in the branches have not all returned to the roots, resulting in excessive waste of nutrients. If pruning is too late, serious bleeding will occur when the branches germinate in the second year, resulting in blocked shoot germination.

2. Trimming objects

When we cut in winter, we should adjust the pruning method reasonably according to the variety, age, tree vigor, planting environment and planting technology. We should not cut blindly. The main object is still to give priority to the fruit mother branches of kiwifruit trees, and all thin branches, pest branches, overlapping cross branches, etc. should be thinned out. For some of the value of no use of excessive growth branches do not bear to cut off in time. After pruning, apply proper amount of antiseptic film to the wound of kiwifruit branches to improve the healing speed of wounds and avoid bacterial infection.

3. Trimming parts

When pruning, we should control the length of pruning according to the growth of branches. If the growth is strong, then about 10 buds can be left, otherwise the number of buds left in the branches should be reduced. If it is multi-main vine frame shape, then in winter shear to appropriate less branches. For the preservation of the fruiting mother branch, the moderate branch should be reserved properly when the space is sufficient, and the full bud should be reserved when the cut is cut. When pruning excessive long branches, it is necessary to retain about 3 buds for short cutting, and if there are new branches, they can be cultured into long vine trunk branches.

4. Winter shear

The main purpose of winter pruning kiwifruit trees is to allow kiwifruit trees to form skeletons according to the ideal shape. Rationally distribute all levels of branches on kiwi trees on the support. Regulate the growth contradiction between growing branches and fruiting branches. And control the number and proportion of fruiting branches and developing branches. Cut off old and weak branches, diseased branches and other branches without use value, improve the fruiting years and fruiting efficiency of kiwifruit trees.

The above is a simple introduction to how to determine the winter shear time of kiwi fruit. Today's introduction is here, this article is for reference only, I hope to help everyone oh!
