Grape pruning is skillful. Friends who like to grow grapes should pay attention. It is necessary to prune grapes regularly, because it is also one of the factors conducive to grape growth. Therefore, plastic trimming must be done well.

Grape pruning is tricky.

(1) Generally speaking, garden grapes should be shaped with multiple main vines or double main vines. The disadvantage of pruning long vines is that the seed setting rate of mother branches is low, and the middle and lower parts of main vines are easy to be blind and the yield is not high. The solution is to strengthen pruning in summer, strictly control the remaining 4-5 branches in that year, and pull out all the others to ensure their good growth and maturity.

(2) Prune 1. Summer pruning: Summer pruning of courtyard grapes is very important. After the inflorescence is exposed, no matter "twins" or "multiple births", only one stout fruiting branch or developing branch remains. Weak branches, hidden bud technology and over-dense branches are all eliminated. In order to improve the fruit setting rate, it is also very important to pick the top of the fruiting branches before or at the initial flowering stage, especially for varieties with serious flower and fruit drop. The core picking position can be carried out where 5-6 leaves are left on the ear, and the tip of the ear picking is one third or one quarter of the lower part of the ear. The treatment of secondary buds is to leave 1-2 secondary buds at the coring place, remove all the others, and then leave 2-3 buds for repeated coring.

2. Pruning in winter: The method of pruning grapes in winter should be mainly plastic surgery. In addition to extending the branches, the trunk shaping is trimmed with 2-3 short shoots.

After pruning, even if the fertilizer is supplemented, the water-soluble fertilizer of the leaves of the prostrate stone nest can be used, which has high absorption rate and is helpful for the tree to restore health.
