How to determine the winter pruning time for kiwifruit? The latest method is here
Kiwifruit cultivation is very common in our country, and now as the temperature gradually drops, it has entered winter. And after winter arrives, the winter pruning work for kiwifruit is very important. Whether winter pruning is successful or not will gradually affect the yield of kiwifruit the following year, so everyone needs to pay special attention to it. So how should the winter pruning time for kiwifruit be determined? Below, the editor will give you a brief introduction. Let's take a look together!
1. Winter pruning time
When pruning kiwifruit in winter, the first thing we need to pay attention to is the time. It should begin about half a month after the kiwifruit trees shed their leaves, usually starting in mid-December and continuing until before the Beginning of Spring the following year. Among these, it is best to carry it out around the three weeks before and after the Winter Solstice. Timing is very important and must not be too early or too late. If pruning is done too early, the nutrients in the branches have not yet all flowed back to the roots, resulting in excessive waste of nutrients. If pruning is done too late, when the branches sprout the following year, a serious bleeding phenomenon will occur, causing the tree's sprouting and budding to be hindered.
2. Pruning targets
When winter pruning, we should reasonably adjust the pruning method according to the variety, tree age, tree vigor, as well as the planting environment and planting techniques, and must not prune blindly. The main target should still be the fruiting mother branches of the kiwifruit trees, removing all thin and weak branches, diseased and pest-infested branches, and overlapping and crossing branches. For some excessively vigorous vegetative branches with no useful value, do not be reluctant to part with them either; they should be cut off in time. After pruning, apply an appropriate amount of antiseptic film to the wounds on the kiwifruit branches to increase the healing speed of the wounds and avoid bacterial infection.
3. Pruning parts
When pruning, we should control the pruning length according to the growth vigor of the branches. If the growth vigor is relatively strong, then about 10 buds can be retained; otherwise, the number of buds retained on the branches should be reduced. If it is a multi-main-vine trellis form, then appropriately fewer branches should be retained during winter pruning. For the retention of fruiting mother branches, when space is sufficient, moderate branches should be appropriately retained to fill gaps, and full buds should be retained at the cut. When pruning excessively vigorous branches, about 3 buds should be retained for short cutting, and if new branches sprout, they can be cultivated into long vine framework branches.
⟦NL>4. The role of winter pruning
The main purpose of winter pruning kiwifruit trees is to enable the kiwifruit trees to form a framework according to the ideal shape. The branches and vines at all levels on the kiwifruit trees should be reasonably distributed on the support. The growth contradiction between vegetative branches and fruiting branches should be well regulated. And the number and proportion of retained fruiting branches and vegetative branches should be well controlled. Branches with no useful value, such as old, weak, and dead branches and diseased branches, should be cut off to improve the fruiting years and fruiting efficiency of the kiwifruit trees.
The above is a brief introduction to how the winter pruning time for kiwifruit is determined. That is all for today's introduction. This article is for reference only, and I hope it can help everyone!
