Provided is a method for improving the shaping quality of photinia fraseri. Pruning is performed at appropriate time. Commonly, after one round of germination, appropriate pruning time is up when lignification of most branches happens, time before or after May Day is appropriate in spring, and early September is appropriate in summer. A certain technology is needed during pruning, a pruning person needs to consider the ecological habit of the photinia fraseri to perform reasonable and moderate pruning and also considers the attractive shape. The development speed of photinia fraseri branches is high, and the photinia fraseri is a tree which is extremely resistant to pruning and easy to shape. In the high-temperature season of the summer, it is not appropriate to perform cutting back and serious cutting back, and otherwise, the tree vigor is difficult to restore after the plant is pruned. Curing is performed after pruning, and after the attractive shape is formed through pruning, how to keep the attractive shape is an important problem. The germination speed of the photinia fraseri branches is high, and therefore the shape can be easily damaged after pruning. A technician needs to consider the problem that the shaping quality may be damaged, the shaping quality of the photinia fraseri is improved on the premise that the shape is maintained, and the attractiveness degree is improved.
