The pruning and shaping of Chinese rose flowers are generally carried out before the germination of new buds in early spring, and it is best to finish it when the dormant period of Chinese rose flowers ends and the axillary buds begin to swell. The basic principle of pruning is to decide whether to re-prune, medium prune or light prune according to the degree of frost damage of rose in winter and the growth habits of varieties. According to the cultivation methods, Chinese rose can be divided into short dry type, dry type and Gao Qian type (umbrella type). Short stems are cut off at the base of branches by 3 ~ 5 cm, leaving 5 ~ 15 growth points. More stem is to keep 3 ~ 5 branches, with 5 ~ 7 strong buds on each branch. Gao Qian type (cultivated for 3 years) keeps the stem with the height of 60 ~ 100 cm and 3 ~ 4 branches at the top. Roses sprout strongly and grow vigorously, and they are pruned all year round. Through pruning, the landscape conditions are improved, so that plants are strong and flowers are more and more vigorous. Pruning in growth period mainly includes removing residual flowers, stripping buds and picking buds. After each flower withers, cut off the remaining flowers. After the first flowering, leave 3-4 buds on the strong branches and 65,438+0-2 buds on the weak branches for cutting again. After the second and third flowers, cut them lightly, only at the second leaf under the residual flowers, so as not to affect the tree potential due to bleeding. After flowering in autumn, it should be cut off in the middle, leaving 2 ~ 5 bud shears for each branch, and paying attention to thinning out long branches and sprouting branches.
