Circumcision of jujube trees, also called nail opening, can prevent nutrients from being transported to the root system, so that jujube trees can blossom and bear more fruits and achieve high yield.
Jujube tree girdling is generally carried out when the flowering amount of the whole jujube tree reaches 30%-50%. At this time, ring cutting can improve the fruit setting rate of jujube trees. However, some varieties are easy to drop fruit after fruit setting, so they should be circumcised at the end of flowering.
Although girdling can improve the flowering and fruit setting rate of jujube trees, not every jujube tree is suitable for girdling. Generally, small trees and weak trees can't be cut around, which is easy to cause tree death. Generally speaking, 3-4-year-old and vigorous jujube trees are suitable for ring cutting.
In fact, ring cutting will be used in many agricultural fields, such as ring cutting of pine trees and rubber trees. These are all for getting juice from trees, and the juice they secrete has many uses. However, many fruit trees also need to cut annual rings. The purpose of cutting annual rings is not to get sap, but to have other uses.
So let's talk about why jujube trees cut annual rings. Generally, jujube tree ring cutting is at the end of flowering and has basically entered the fruiting period. The role of ring cutting is because a lot of nutrients are needed in the fruit-bearing period, thus promoting fruit growth. The purpose of girdling is to prevent the nutrients of branches from flowing back to the roots through the bark, so as to improve the fruit setting rate of jujube trees and increase the yield of fruit trees.
Matters needing attention in ring cutting
Circumcision of jujube trees is not possible under any circumstances. Generally, jujube trees with vigorous growth should be selected, and moderate girdling should be carried out according to different tree ages in sunny and sunny days. Generally, the thickness of the foreskin is about one centimeter, up to the wood part. After the cut bark is cut off, it is best to wrap it with plastic film, which is more conducive to the healing of jujube trees.
After the link, it cuts off the passage to the root or other branches, so that nutrients will accumulate on the girdling, so that the leaves, flowers and fruits of jujube trees have enough nutrition, which can improve the yield of jujube trees and enhance the growth of trees.
