How to trim the grapes in summer?

How to trim the grapes in summer? Please introduce the pruning method for summer grape pruning can refer to the following methods: shoot removal is generally carried out during the period from grape sprouting to inflorescence exposure, and the earlier the shoot removal, the less nutrient consumption. The method is to remove all the germinated buds, concurrent buds, fine and weak buds, disease and insect buds, over-dense buds and buds with less fruit on the trunk and old vines, so as to make the retained buds distribute evenly, grow healthily and promote the results. In principle, the time and time of heart picking should be determined according to the variety, tree potential and pruning method. Picking the heart at flowering stage can stop the growth of new shoots for 10-15 days, make nutrients flow to inflorescence, ensure good pollination and improve fruit setting rate. The fruit-bearing branches with strong growth leave 4-6 leaves above the inflorescence, extend the branches with 12-20 leaves, and prepare the branches with 10-15 leaves, which is beneficial to promote fruit ripening and accelerate the Lignification of branches. When the sprout is too prosperous, it is necessary to pick the heart for many times to control the growth of branches and reduce the consumption of nutrients. In the auxiliary shoot treatment, all the secondary shoots in the lower part of the ear should be removed, 1-4 leaves can be left in the upper part, and the secondary shoots that occur later should be removed except for the top vine. Leave 2-3 leaves on the secondary tip of the growing vine to pick the heart, and if there is a flower ear that germinates later, it can be retained, otherwise only the top one will be left, and the rest will be removed. Annular peeling in the middle of the lower segment of the ear, peel off the 3-5 mm cortex around the vine with a knife or circular peeling shears. Remove tendrils and bound vines to save tree nutrition, tendrils should be removed as much as possible. The 2-3 young tendrils at the tip are best retained to maintain the dominance of the growth point and remove the beard when the new shoot extends more than 25 cm forward. In order to prevent the branch vine from breaking and the uneven distribution of the frame surface, the hedge is generally tied up at 30-40 cm of the branch, and the scaffolding is generally tied up at 1 meter of the branch. In order to improve the light conditions near the ear, some of the old leaves should be removed to promote the coloring of the fruit. Leaves are usually picked when the fruit becomes soft.
