One, summer scissors
Summer includes the entire period from the time the grapes are sprouted to their resting state. (1) wipe buds. After the grape sprouts in spring, each main vine spreads out its head and removes the useless shoots of the main vine. The result is that the buds, double buds, weak buds, and other unwanted sprouts on the mother twig retain the strong buds, and Before flowering, remove redundant branches and thin and weak branches 2-3 times and strictly control the number of new shoots to ensure their quality. (2) set the tip. The shoots are mainly cultivated to result in branches and branches, and the positions of each shoot are reasonably allocated. At the same time, the principle of sparsely populated and weak trees is grasped. The main vines that have been climbed are left with only about 50 centimeters in the upper part and weak branches. Branch, to achieve the purpose of pressing the crown and weakening the top edge. The 2 year old trees are cut off from the new shoots below 80 cm in the main vines, and 80 cm or more are left to stay in place or to stay in place. Weak trees often go to weak branches and early shoots; Wang branch left a bunch of fruit, weak branches firmly determined to fruit. (3) Topping up. The main vine extension branch leaves no fruit, should be timely picking the heart to help the strong; the main vines left on the new shoots of weak branches in the 4-6 leaves topping, Zhuangzhi 8-10 leaves topping; results 4-6 before the branch spikes Leaf topping. Topping should begin 3 days before flowering and 2-3 days assault. (4) go to the auxiliary tip. The general results of the branch in addition to leaving the top two secondary shoots, development branches in addition to the top of a secondary tip, the remaining auxiliary tip all erased, leaving the secondary shoot 2-3 leaves repeatedly topping. In order to enhance the leaf area and increase the amount of shoots, 1-2 leaves were left when the sub-apparents were removed, or 1-2 sub-shoots were kept at the base, and the hearts were repeatedly picked up. In addition, the tendrils must be removed in time. (5) Sparse whole flowers. The method is to remove the small, dense and irregular flower spikes immediately after the new shoots are removed. Each new shoot is left with 1-2 inflorescences, and the main inflorescences are mainly the lower part of the remaining shoots. The shearing should be carried out 10-15 days before flowering. Go to the deputy panicle, then pluck 1/4-1/3 of the spike tip, and thin the fruit after the fruit is set. First remove the small seedless fruits, the deformed fruit, the disease and fruit, and finally remove the dense fruit.
Second, winter shear
Grapes are pruned in winter, generally about 1 month after falling leaves in autumn to about 20 days before the germination of the following year. The principle is to keep strong vines and stay long, with weak vines and short stays; the upper ministers stay and the lower part stays short. (1) Long vine pruning. In the resulting mother vines, one vine was selected as the updated mother branch, and the updated mother branch retained 2-3 healthy shoots. As a result, the mother vines retained 6-12 shoots, prompting the flowering shoots to bloom in the year. By the next winter cut, all the results will be cut off and the new shoots on the upper part of the vines will be renewed. 6-12 shoots will still be retained. As a result, the lower shoot will retain 2-3 buds. As an update female vine. (2) Short Mantis trim. When winter cuts, leave 2-3 buds for each result. After the spring draw, select the upper branch as the result branch, and the lower branch as the update branch, do not let the result. When pruning in winter, the result branches are all cut off and the renewing branches are left with 2-3 buds. (3) Manzhong trim. The vine pruning and renewal methods are basically the same as the short vine pruning. The difference is that the resulting mother shoots have a larger number of buds, generally leaving 4-5 buds. In addition, dense branches, delicate branches, pests and branches, and dry branches should be cut off during pruning.
