The latest summer pruning methods and benefits of kiwifruit

Kiwifruit is a kind of fruit with high nutritional value, which has a very large planting area in our country. When planting kiwifruit, we should pay attention to the management work, especially pruning, now gradually into the summer, summer cutting work is also particularly important. So what are the benefits of reasonable summer pruning when we grow kiwifruit? How to trim it? The following editor will give you a brief introduction, let's have a look!

1. Benefits of summer clipping

Proper summer shearing of kiwifruit can effectively improve the permeability of the field, promote ventilation and improve the rate of flowering and fruiting. Prevent the yellowing and aging of leaves in some uneven places of light, improve the accumulation in the plant, and increase the storage and transportation capacity of kiwifruit. And proper summer pruning can also effectively reduce excessive nutrition consumption, concentrate nutrition on the fruiting mother branch, improve the positive flower rate and the growth ability of leaves, and prevent the phenomenon of falling leaves and flowers. Finally, it can effectively prevent the occurrence of diseases and insect pests, such as leafhopper, black spot and so on.

2. How to cut in summer

Pick the heart properly

We should pay attention to observe the growth of kiwifruit when we plant kiwifruit, and we can start summer pruning work around July. Because this is the peak time for the growth of summer shoots of kiwifruit plants, it is necessary to pick the heart properly. Prevent the occurrence of winding, overgrowth and other adverse phenomena, disperse nutrition and affect the growth of kiwifruit. The nutrition is concentrated on the fruit to promote the development of the fruit and improve the quality. Then carry out the second coring when the branches are twining, and the time should be reasonably controlled according to the growth of the kiwifruit tree.

Thinning and pruning

When picking the heart, we also need to do a good job of thinning and pruning, which is also around July. First of all, we thinned the branches for the base and some main vines that are too long and too dense, diseases and insect pests and other branches. Then do a good job of cross-overlap, upright growth and weak branches to improve the overall growth of kiwifruit, promote the growth of kiwifruit, increase the permeability of the orchard, and ensure that kiwifruit trees receive light evenly. When thinning branches, we should pay attention to keep a new shoot every 12 centimeters or so on the fruiting mother branch, so as to avoid the decline in growth, which is counterproductive.

Reasonable fruit thinning

After the work of picking the heart and thinning branches has been done from July to August, fruit thinning will begin. It is also best to keep it around July-August and not beyond September at the latest. During the period of fruit growth, the main fruit thinning objects are weak and small fruits such as diseases and insect pests, deformities, burns and overdensity, which have very low commercial value and consume a lot of nutrients. Therefore, we should aim to keep the fruit which is strong, stout, full and juicy. When thinning the fruit, it should be carried out reasonably according to the growth of the branches. generally, there are about 5 strong branches and 3 moderate branches, followed by one, and the ratio of leaves to fruits on the fruit tree is controlled at about 4: 1.

The above is a brief introduction to the summer cutting methods and benefits of kiwifruit. The pruning of kiwifruit is very important, which not only has a great impact on the yield, but also determines its quality, so we must pay more attention to it. That's all for today's introduction.
