Kiwifruit ring cutting methods and precautions

Ring cutting is one of the tasks often done in the process of kiwifruit planting, which is mainly used to interrupt the transportation system of the bark, so that photosynthetic synthetic substances can not be transported downward, so as to increase the accumulation of organic matter in the fruit and increase the yield. So how to do ring cutting? What should ring cutting pay attention to? Let's get to know it.

1. Ring cutting position and tree age

The best choice of kiwifruit ring cutting position is on the trunk, generally for older and vigorous trees, ring cutting can be done 1-2 times a year, vigorous trees can be cut twice, the middle tree can be cut once, weak trees and trees with diseases and insect pests should not be cut, and ring cutting is not recommended for trees less than seven years old. If inexperienced friends want to try, you can choose to do it on the first or second branch, or cut two and a half circles, stagger up and down, and interval 10cm.

2. Ring cutting time

Most ring-cutting is chosen in July, when the growth period of kiwifruit has entered the sugar conversion period, when the summer shoot grows very fast, competing for water and fertilizer with the fruit growth and development. Therefore, summer shearing usually needs to be carried out once a month, and ring cutting reduces the content of auxin and increases ethylene, so as to inhibit vegetative growth, promote reproductive growth, effectively cap the tip and promote the ripening of branches.

3. Management after ring cutting

Ring cutting time is in a high-temperature and high-humidity environment, which is very prone to the outbreak of diseases and insect pests, so the wound should be bandaged in time after ring cutting so as not to be invaded by bacteria. Ring cutting will cause tree potential yellowing and decline, so it is necessary to strengthen fertilizer and water management during flowering and fruit expansion, especially to apply foliar fertilizer.

4. Points for attention

When ring cutting, we must pay attention to the strength, do not hurt the xylem, otherwise it will have a great impact on fertilizer and water transportation, ring cutting width is not more than half a centimeter, the distance between the two rings should be more than 10 centimeters. Ring cutting is suitable for vigorous older fruit trees, but ring cutting is not recommended for orchards less than 7 years old, young trees and diseased trees are not recommended, tools should be disinfected during ring cutting, and one of each treatment should be disinfected to avoid the spread of diseases among fruit trees. The second ring cutting should be carried out after the healing of the first ring cutting wound, ring cutting can not be carried out on all branches, the two ring cutting distance can not be too close, it is easy to peel.
