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 China. When planting kiwifruit, we should pay attention to the management work, especially pruning. Now, after entering summer gradually, summer shearing work is also particularly important. So what are the benefits of reasonable summer pruning when we plant kiwi fruit? How do you trim it? The following small series will briefly introduce you, let's take a look together!

1. Summer shear benefits

Proper summer pruning of kiwifruit can effectively improve field permeability, promote ventilation and ventilation, and improve flowering and fruiting rate. To prevent some of the uneven exposure to the leaves of the phenomenon of yellowing aging, improve the accumulation of plants, increase the storage and transportation capacity of kiwifruit. And proper summer pruning can also effectively reduce excessive nutrient consumption, concentrate nutrients on the fruiting mother branch, improve the positive flower rate and leaf growth ability, 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 summer

proper topping

We should pay attention to the growth of kiwifruit when planting, and we can start summer shearing work after entering July. Because this time is the peak growth period of kiwifruit plants in summer, it is necessary to properly pick the heart. Prevent various undesirable phenomena such as entanglement and excessive growth, disperse nutrients, and affect the growth of kiwifruit. Concentrate nutrition on fruit, promote fruit development and improve quality. Then, when the branches are entangled, the second topping should be carried out, and the time should be reasonably controlled according to the growth of kiwi trees.

pruning

We also need to do a good job of thinning and pruning when picking, and the time is also around July. First of all, we sparse branches for the base of the object and some of the main vine on the too long too dense, pests and other branches. Then cross overlapping, upright vigorous growth and thin branches are done well to improve the overall growth of kiwifruit trees, promote the growth of kiwifruit trees, increase the permeability in orchards, and ensure that kiwifruit trees receive uniform light. When thinning branches, pay attention to keeping a new shoot every 12 cm or so on the fruiting mother branch to avoid growth decline, which is counterproductive.

rational fruit thinning

In July-August to do a good job of picking branches, then start thinning fruit. It is also best to keep the time around July and August, and not to exceed September at the latest. During the fruit growth period, the main fruit thinning objects are small fruits such as pests, malformations, burns, and over-dense. The commodity value of these fruits is very low, and a large amount of nutrients are consumed. Therefore, we should aim to preserve healthy, thick, full and juicy fruit. When thinning fruit, it should be carried out reasonably according to the growth of branches. Generally, about 5 strong branches should be reserved, about 3 moderate branches should be reserved, and then one should be reserved. The leaf-fruit ratio on the fruit tree should be controlled at about 4:1.

The above is a brief introduction to the methods and benefits of kiwi summer shearing. Kiwi pruning is very important, not only has a great impact on yield, but also determines its quality, so we must pay more attention.
