Winter pruning of grapes is a more complex and critical technique. Pruning can affect the growth and development of grapes 2 to 3 years after the next year or even later. It is important to master the trimming technique correctly. During the pruning period, the winter grape cutting period in the greenhouse cultivation should be carried out after the grape plants fall into the deep dormancy after falling into leaves. Generally, it is completed from mid-December to the end of December, and it will affect its subsequent management work too late. The pruning method is decided according to the different types of cultivation, the characteristics of the varieties, and the strength of the tree vigor. The specific method of cutting. First cut out the pests, and overdraw the twigs that are too thick (the diameter of the parent base is more than 1.5 cm on the main branch). Different frame-type pruning greenhouses are generally used in the cultivation of grapevines, V-shaped racks and small scaffolds. Two years before fruiting, a hedgerow was used, and the fruit was mainly V-shaped. When the hedge trimmer is selected, the results will be selected to stay in the direction of the parent vines, and the V-shaped frame results in the selection and retention of the parent vines on both sides. The small shed should be used to ensure that the plant distance is relatively high. The rod shaping method directly selects and retains the resulting mother branch on the main vine. Pruning according to species characteristics Most Eurasian species have the disadvantages of strong growth and flowering in local cultivation. The quality of fruit grown in greenhouses is better than that of European and American hybrids. Such as purple crisp, early red, summer solstice, etc., the pruning of this species should be used in the long tip scissors, the results of the golden branch mother leaves 4 to 6 buds short cut. As a result of the prosperous results, 6 to 8 buds were cut in the mother tree. Amount of buds per mu is 7000~8000, so that preparation can be adjusted when the panicles can be identified later. Yi Jinhua grows its golden mean varieties such as Ziyu, Venus, Wu Teng, etc., and implements 2 to 3 bud shoots on the resulting mother trees. The amount of mu leaves is about 5,000.
