Actinidia chinensis heart picking technology

Kiwifruit, also known as kiwifruit, its nutritional value is very high, in order to ensure the normal growth of kiwifruit, improve yield and fruit quality, it is very important to do a good job of kiwifruit coring. So why on earth do you want to pick the heart when you grow kiwifruit? When should I pick my heart? How can we pick the heart? The following editor brings you the heart-picking technology of kiwifruit, let's have a look!

1. Why pick the heart?

After entering May every year, the growth of kiwifruit will reach a peak period, and the growth rate of new shoots is very fast. If it is not managed in time and allowed to grow, then it is easy to grow branches. As a result, the branches are too long and dense, the crown is closed, and the permeability is very poor. Lead to excessive nutrition consumption, but also affect the expansion of kiwifruit and reduce the quality of kiwifruit. And it will also have an impact on flower bud differentiation in the second year, so we must do a good job of heart-picking.

2. Time to pick out the heart

The time of coring depends on the planting variety, which usually starts in June, and if it is a variety such as Hongyang, it can be carried out in mid-May. The frequency of heart-picking is controlled at about half a month, so we should pay attention to the position of heart-picking. For some reserved branches, we should pay attention to control the heart-picking strength, not blindly pick the heart. Generally speaking, when the winding phenomenon occurs at the top, the core is picked, and then when the secondary branch is wound, it is necessary to pick the heart again.

3. Core-picking technology

Young trees pick their hearts

The coring technique varies with the age of the tree, and the trees that grow within two years are called young trees. If it is a young tree that has just been planted that year, then keep two or so branches, and when the branches grow to about 75cm, pick the heart in time. Then let it grow naturally, and for some prosperous trees, it is necessary to pick the heart around the 35cm. If the growth is weak, then the appropriate reduction of about 15 centimeters. Observe the growth of the main vine after picking the heart, it is not unexpected that about 3 side branches will germinate, at this time the opposite side branch will retain about 10 leaves to pick the heart again.

Fruit trees plucking hearts

For the heart-picking of fruit trees, we should carefully observe the growth of kiwifruit trees and retain about 6 leaves from the top branches of the outer branches for the first time. Then pick the heart again when the new branch grows 3 leaves, and then increase the heart-picking strength for some overgrown branches. When we pick the heart, we should also pay attention to do a good job of thinning branches, improve permeability, reserve a certain growth space for each branch, remove the excess branches from the base, and provide sufficient light for the inner branches.

The above is a brief introduction of kiwifruit heart-picking technology. When we pick the heart, we should pay attention to the heart-picking object, mainly permanent branches, overgrown branches, fruiting mother branches and other branches, according to the actual situation to ensure the normal growth of kiwifruit. That's all for today's introduction. This article is for reference only. I hope it can help you all.
