The current characteristics of jujube tree pruning

Jujube buds have four main buds, deputy buds, hidden buds, and adventitious buds. Branches have date head (development branch), secondary branch (result base branch), date stock (result mother branch), date hanging (result branch) The four species are unique in their growth and pruning compared to other fruit trees.
First, the tree crown expansion is slow, the first year after planting is very slow growth and even some farmers call it suspended animation, 2 to 3 years after the unilateral extension of the jujube head, shoots with large growth but the branch is small, although 2 to 4 years can flower However, there are few results. Therefore, in the trimming, the crown is enlarged and the main branch is cultivated.
Second, jujube tree branches dull response, many old fruit areas have "two scissors hair sticks, a result of a scissors" argument, to increase the amount of branches only on the jujube head short cut, and eliminate the second branch can stimulate the jujube The main buds of the leafhoppers germinate. After the canopy is basically formed, except for the extension of the main branch, the removal of the buds from the excess jujube head can promote fruit set.
Third, do not deliberately cultivate the results of Zhizu, jujube tree results Zhizu is the second branch of the jujube head and the date of the jujube stocks on it, the result is a branch with the growth of the jujube head naturally produced, the result is relatively stable.
Fourth, trimming technology is relatively simple. There are few jujube branches, and the winter pruning only involves the cultivation of the branches, the adjustment of the affiliation of the branches and the renewal of the senescence shoots. The orchards of some jujube-intercropping intercrops in the city only undergo a small amount of thinning and short cutting in winter. In summer, pruning mainly focuses on keeping flowers and fruits to increase the fruit setting rate.
