Detailed Explanation of the Latest Technical Points for Spring Management of Kiwifruit

Kiwifruit is a fruit extremely high in vitamins, and it 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 been bred, such as red-fleshed kiwifruit, hardy kiwifruit, and others. 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 together 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 early spring in many places. This also reminds us that in early spring it is still necessary to take frost prevention measures to reduce unnecessary damage. Generally, if the temperature in early spring is lower than two degrees, we need to do a good job of prevention, and we can use smoking or whitewashing the 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 so in spring, but this is actually a mistaken idea. In spring we still need to carry out supplementary pruning of kiwifruit branches and leaves, because winter pruning is very likely to miss some diseased and pest-infested branches or dead branches. Second, we also need to prune excess vegetative branches. Finally, we also need to carry out pinching, bud removal, and flower bud thinning on kiwifruit so that it 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 and branches of the kiwifruit, and then tie them 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 buds appear, all flower buds on the main branches and vines should be thinned out, and then a layer of branch-promoting agent 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 to the trellis to grow by trailing above it, reducing the harm of diseases and pests.

4. Apply spring fertilizer

Spring is the peak season for kiwifruit to shoot, 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 mainly urea, combined with an appropriate amount of compound fertilizer. When fertilizing, trenching and ring application are generally used, and care should be taken not to damage the kiwifruit root system. After fertilizing, watering should be carried out, 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 budding, 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 and 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 reading and supporting.
