Detailed Explanation of Key Points of Summer Management Techniques for Kiwifruit
Kiwifruit is relatively common in China and is a fruit with great market demand. It is distributed throughout China. When growing kiwifruit, we need to adjust our management methods according to seasonal changes. Especially during the high temperatures of summer, the quality of management directly affects the yield and quality of kiwifruit. So how should it be managed in summer? Today, the editor brings you the summer kiwifruit management techniques. Let's take a look!
1. Summer Pruning
In summer, pruning work for kiwifruit is very important. Summer is generally the bud stage for kiwifruit. When kiwifruit has just budded, bud thinning should be done well. Remove overly dense buds in unsuitable growing positions as well as flowerless buds, then carry out pollination, and after pollination, pinch the tips. The main targets for pinching are vines that have grown about 20 leaves, removing the top shoot with 3-4 leaves. If the number of leaves is above 35, then remove about 5 top shoots. After pinching, if there are new shoots, remove them promptly or pinch them again.
2. Fruit Management
In summer, we should pay attention to fruit thinning to avoid the fruit load exceeding the tree's carrying capacity. When thinning fruit, the main approach is to keep a single fruit per inflorescence and remove the top fruit and tail fruit on the same branch. The fruit retention for long branches should be kept at about 4, about 3 for medium branches, and just 1 for short branches. When growing them, to improve fruit quality, it is best to bag the fruit. Half a month after pollination of the kiwifruit tree, spray foliar fertilizer, with urea as the main fertilizer and micro-fertilizers as supplementary. After that, spray once every two weeks, for about 5 consecutive sprays. After the young fruit stops growing for the first time, apply a fruit-strengthening fertilizer once, with nitrogen and potassium fertilizer as the main components.
3. Branch and Leaf Management
Branch and leaf management is also a key point in summer kiwifruit management. For some kiwifruit varieties, the leaves are relatively thin and large, so their stress resistance is not strong, and they are easily broken by wind. Therefore, in strong wind weather, we should do a good job of tying branches and guiding vines. In particular, pay attention to branches that are easily broken by wind; most of these branches are the fruiting mother branches for the next year. If dry hot wind occurs, then appropriately spray water on the leaves to prevent the leaves from being scorched. When establishing an orchard, it is best to choose leeward areas, and if conditions permit, build a good shelterbelt to improve the orchard's microclimate and ensure normal growth of kiwifruit.
The above is a brief introduction to summer kiwifruit management techniques. In addition to the above, the most basic water and fertilizer management as well as intertillage and weeding are also things we cannot ignore in management, so everyone must pay more attention to avoid affecting the growth of kiwifruit. That is all for today's introduction. This article is for reference only, and I hope it can be helpful to everyone!
