How to Pinch Kiwifruit: Latest Technical Method Tutorial

Kiwifruit is also called kiwi, and its nutritional value is very high. When growing kiwifruit, to ensure normal growth of the kiwifruit and improve yield and fruit quality, doing a good job of pinching kiwifruit is very important. So why exactly should kiwifruit be pinched when growing it? When is the best time to pinch? And how should we pinch? Below, the editor brings you the pinching technique for kiwifruit. Let's take a look!

1. Why pinch

Every year after entering May, the growth of kiwifruit will reach its peak period, and the growth rate of new shoots is extremely fast. If it is not managed in time and allowed to grow freely, then the phenomenon of excessive vegetative growth of branches is very likely to occur. This leads to branches being too long and too dense, the canopy closing up, and extremely poor aeration and light penetration. It causes excessive nutrient consumption, and will also affect the swelling of kiwifruit fruit and reduce quality. And it will also affect the flower bud differentiation of the second year, so we must do a good job of pinching.

2. Pinching time

The pinching time should be determined according to the planted variety. Generally it starts in June. If it is a variety such as Hongyang, then it can be done in mid-May. The frequency of pinching should be controlled at about half a month, and attention should be paid to the pinching position. For some reserved branches that are kept, attention should be paid to controlling the pinching intensity, and pinching should not be done blindly. Generally, pinching is carried out when twisting appears at the tip, and then pinching should be done again when the secondary branches twist.

3. Pinching technique

Pinching young trees

The pinching technique will also differ according to tree age. Trees growing within two years are called young trees. If it is a young tree just planted in the current year, then keep about two branches and vines, and when the branches and vines grow to about 75 cm, pinch at the appropriate time. Then let them grow naturally. For some trees with vigorous growth, pinch at about 35 cm below the trellis surface. If the growth is weaker, then appropriately reduce by about 15 cm. After pinching, observe the growth of the main vine. Barring accidents, about 3 side branches will sprout. At this time, keep about 10 leaves on the side branches and pinch again.

Pinching fruit-bearing trees in full production

For pinching trees in full production, we should carefully observe the growth of the kiwifruit trees, and carry out the first pinching from the top branches of the outer branches while keeping about 6 leaves. Then pinch again when the new branches grow 3 leaves, and then for some excessively vegetative branches, increase the pinching intensity. When pinching, we should also pay attention to doing a good job of branch thinning to improve aeration and light penetration, reserve a certain growth space for each branch, thoroughly remove excess branches from the base, and provide sufficient light for the inner canopy branches.

The above is a brief introduction to the kiwifruit pinching technique. When pinching, we should pay attention to the pinching targets, mainly permanent branches and vines, excessively vegetative branches, fruiting mother branches and other branches, and pinch separately according to the actual situation to ensure normal growth of kiwifruit. That is all for today's introduction. This article is for reference only, and we hope it can help everyone!
