What are the key technical points for spring management of kiwifruit?

Kiwifruit is a fruit extremely rich in vitamins and is also very popular in the market. Kiwifruit originated in China and is a wild edible fruit of China. Now many new varieties of kiwifruit have also been cultivated, such as red-fleshed kiwifruit and hardy kiwifruit. Spring has come around again, and so has the season for kiwifruit branches and leaves to grow. So how should we manage kiwifruit in spring? Let us take a look below at its spring management techniques.

1. Prevent early spring frost damage

The temperature in early spring is actually still relatively low, and kiwifruit has limited cold resistance, so frost damage occurs in many places during early spring. This also reminds us that in early spring it is still necessary to take frost damage prevention measures to reduce unnecessary damage. Generally, if the temperature in early spring is lower than two degrees, we need to do prevention work, and we can use smoke fumigation or whitewashing the tree trunks to prevent frost damage.

2. Spring pruning

Many people think that since branches and leaves were pruned in winter, there is no need to do it in spring. In fact, this is also a mistaken understanding. In spring we still need to do supplementary pruning of kiwifruit branches and leaves, because winter pruning is very likely to miss some diseased and pest-infested branches or dead branches. Secondly, we also need to prune excess vegetative branches. Finally, we also need to pinch the tips, remove buds, and thin flower buds of kiwifruit so that kiwifruit can grow better.

3. Tying branches and vines

Tying the branches and vines of kiwifruit is a very important task. First, we should select the main trunk of the kiwifruit, then tie it along the trellis. During the tying process, we should note that the other branches and vines should remain perpendicular to the main branches and vines, which can promote the sprouting of winter buds. When the buds appear, all flower buds on the main branches and vines should be removed, then a layer of sprouting promoter should be applied to promote the growth of side branches. Finally, excess branches and leaves should be thinned out, and the fruiting branches should be tied above the trellis to grow by climbing, reducing the harm of diseases and pests.

4. Apply spring fertilizer

Spring is the peak season for kiwifruit to sprout new shoots, so its demand for nutrients is also relatively large. In order to promote the growth of kiwifruit branches and leaves, we also need to apply additional fertilizer in early spring. Generally, it is mainly urea, used together with an appropriate amount of compound fertilizer. When fertilizing, trenching and ring application are generally used. Be careful not to damage the kiwifruit root system, and water after fertilizing, which is beneficial to the absorption and utilization of nutrients.

5. Prevent diseases and pests

In spring we need to prepare in advance for the prevention of diseases and pests, such as the prevention of canker and root rot. Before sprouting, we can spray an appropriate amount of Baume-degree lime sulfur mixture in the orchard and drench the roots with hymexazol. Of course, the most direct method is to scrape off all the insect eggs and disease spots on the kiwifruit branches, but note that a preventive agent should be applied to promote wound healing, so as to avoid infection by other diseases.

The above is the spring kiwifruit planting management techniques that the editor has brought to you today. I hope it can help all friends who grow kiwifruit. At the same time, I also hope that everyone will have smooth sailing in the planting process afterward. Thank you for your reading and support.
