Should choose to stay in the winter jujube auxiliary support
The selection of preserved winter date auxiliary support has two purposes: one is to retain the normal growth function of the tree, so that the root system develops normally; the second is to provide nutrients for the result stick group, so that the quality and yield of the fruit are guaranteed; third is to extend the life of the result To prevent premature aging of the tree. Therefore, the selection and retention of supplemental branches is very important.
There are two ways to maintain the selection of auxiliary branches: one is to select old branches, and the other is to select new branches. The selection of old branches cannot be over-aged, nor can they be selected because the functions of these two branches are very weak. They can neither play the role of ancillary trees, nor can they be restored to the next year's results. Therefore, For such branches and branches, 1-2 secondary branches may be retained or not retained, short cuts may be made to promote sprouting of new shoots, new shoots may be cultured, and old branches in the opposite direction may be selected as auxiliary branches. If new shoots are used as supplementary branches, the new shoots germinating last year may not be opened. If the whole shoots have been completely developed, the status quo can be kept as supplementary support branches. If the branches are not long enough, or if the secondary branches are incomplete, they can be on the branches. 2/3 short cuts, continued growth, left as a subsidiary. Another method is to cut the bad branch of the young age group at the bottom and leave 1-2 secondary branches to promote the sprouting of the branches with good angles, and also serve as a supplemental branch. If you want to expand the canopy, you can choose any branch group to carry out a short branch, and then at the second branch of the outreach of the second branch 2-3 truncation, sprouting with the second branch of the sprout and double branch. Note that the selection of new shoots must be done with strong shoots that are germinating. Otherwise, shoots that are barely germinating are generally not ideal. The number of supplementary branches to be taken depends on the size of the canopy. In the case of general water and fertilizer, the auxiliary branches can be left 1/3 of the full crown branches.
