How to manage kiwifruit in spring: fertilisation and pruning techniques

Kiwifruit is a fruit extremely rich in vitamins, and it is also very popular in the market. Kiwifruit originated in China and is a wild edible fruit of China; nowadays many new cultivars of kiwifruit have also been bred, 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. Preventing early spring frost damage

The temperature in early spring is actually still rather low, and kiwifruit has limited cold resistance, so frost damage occurs in early spring in many places. This reminds us that in early spring it is still necessary to take frost damage prevention measures to reduce unnecessary losses. Generally, if the early spring temperature is lower than two degrees, we need to do the prevention work well, and we can use smoking 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 carry out supplementary pruning of kiwifruit branches and leaves, because winter pruning may very likely miss some diseased and pest-infested branches or dead branches; secondly, we also need to prune off surplus vegetative branches. Finally, we also need to carry out pinching, bud removal and flower bud thinning on kiwifruit so that it grows better.

3. Tying the branches and vines

Tying the branches and vines of kiwifruit is a very important task. First we must select the main trunk of the kiwifruit well, then tie it along the trellis. During tying we must pay attention that the other branches and vines remain perpendicular to the main branch and vine, as this can promote the sprouting of winter buds. When the buds appear, all flower buds on the main branch and vine should be thinned out, then a layer of sprouting promoter should be applied to promote the growth of side branches. Finally, surplus branches and leaves should be thinned out, and the fruiting branches should be tied above the trellis to creep and grow, reducing the harm of pests and diseases.

4. Applying spring fertiliser

Spring is the peak season for kiwifruit to put out 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 fertiliser in early spring, generally mainly urea, used together with an appropriate amount of compound fertiliser. When fertilising, ring trenching is generally used, and care must be taken not to damage the kiwifruit root system; after fertilising, watering should be carried out, which is good for the absorption and use of nutrients.

5. Preventing pests and diseases

In spring we need to prepare in advance for the prevention of pests and diseases, for example 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 technique that the editor has brought to you today, and I hope it can help all friends who grow kiwifruit. At the same time, I also hope that your future planting goes smoothly, and thank you all for reading and supporting.
