Natural and artificial regeneration of aged jujube trees

The main branches of jujube branches continue to elongate and droop with the growth of branch age, and it is easy to grow long branches instead of old branches in the changing arch position, which is natural renewal. Senescent trees are less able to renew themselves naturally, but they often grow some developmental branches in bare areas. The regeneration of old branches can be accelerated by combining artificial regeneration with natural regeneration. The method is to sawn off the branches at the front end of the natural renewal branch, and the old branches can be sawed off within one year, or it can be completed in several years. Because the front end is sawed off, the development branch behind is stimulated and accelerated to lengthen, so that the new branch replaces the old branch.
