Results of jujube tree pruning
At the beginning of the result period, the dense development branches other than the central stem, the main lateral branch, and the large-scale result branch should be sparsely sheared, and the space should be reserved to cut off the terminal buds.
The pruning in the full fruit period should pay attention to four points, one is to remove the long, round, cross, and congruent, overlapping branches; the second is to sparsely cut the thin branches and the dense branches; the third is to block the top of the backbone and the appropriate back The fourth is to cultivate a strong result of the branch and the resulting mother branch.
Results During the renewal period, the retraction method was used mostly to retract part of the pendulous brachial branches, and the other faint branches also retracted accordingly, generally retracting to the strong buds with strong vitality. After retracting the backbone branches, a new jujube head is promoted, and the main branches can be gradually cultivated into extension branches and side branches, and the internal condyle is enriched to supplement the space. If a new branch appears on the backbone, it can also be retracted directly to the new branch.
Old Tree Update Prune
Light update When the effective date stocks are around 1000 to 1500, a mild retraction method can be used to cut off 1/3 of the total length of each bone branch, and the tree vigor can be enhanced and the result can be continued.
When the medium-renewal product is about 500 to 1,000 jujube stocks, it can adopt a medium-retraction method, saw 1/2 of the total length at the strong stocks and latent buds, so that it can sprout new shoots, and at the same time strengthen the management of the tree and raise Trees can restore tree vigor in 1 to 2 years, with normal results.
When re-updating general effective date stocks from 300 to 500, we must adopt a method of renewing them. We also select strong stocks and latent buds, saw off 2/3 of each backbone branch, make it sprout new branches, re-form the crown, and then Strengthen the tree under the tree management, tree maintenance for 2 years (without opening A) to restore normal results.
To update the old tree, pay attention to the relationship between the master and the slave. Cut out the mouth with a wax coating to prevent cracking of the wound. Store the rain to rot. Backbone branch updates must be completed at one time and cannot be performed in batches. Most importantly, renewal pruning should be carried out on the basis of strengthening the management of underground manure and water.
