Plastic pruning of sunshine rose

The hedge cultivation of sunshine rose grape is mainly based on natural fan pruning. Pruning in winter is generally carried out from about 1 month after defoliation in autumn to about 20 days before germination in the following year. Pruning too early or too late will cause serious damage to trees, loss of nutrients and weak plant growth. According to the strength of the tree and the length of the bearing branches, pruning methods are adopted: strong vines stay long, weak vines stay short, upper vines stay long, and lower branches stay short.

Knock out all the growth secondary branches of the 1 year-old main vine, leaving only one trunk, leaving 2-3 buds for each bearing branch of the bearing tree, and removing the strong ones after budding and promoting the weak ones. Pay attention to timely and reasonable renewal of branches and vines, regulate vegetative growth and reproductive growth, and prevent the fruiting parts from moving up. In the germination stage, the new buds within 50 cm from the ground should be smeared in time, and the second smear should be carried out after 10 to smear the new buds with weak growth, abnormal growth and incorrect position.
