Pruning of Gonggan mandarin orange:

1. Pruning of young trees

Generally speaking, the best canopy shape for Gonggan mandarin orange trees is the round-headed type. For the pruning of young trees, bud thinning and shoot fixing should be carried out at the right time, that is, keep 2 to 3 new shoots on relatively thick branches, while keeping only 1 on weak branches. When new shoots grow to about 20cm, pinch them promptly to shorten the shooting cycle and promote the rapid greening of new shoots, thereby laying the foundation for forming an ideal canopy.

2. Pruning of bearing trees

The main work is to cut off dead branches, diseased branches, crossing branches in the inner canopy, and branches with poor fruiting capacity, etc. In addition, about 15d before the trees put out autumn shoots, pruning can be used to cultivate robust autumn shoots. The specific method is: for fruit-dropping and flower-dropping branches, broom branches, and declining branches in the middle and upper parts of the canopy, short cutting should be adopted to remove them, while branches that bear too many fruits, bear diseased fruits, or have overly small fruits should also be cut off in time.
