After the grape harvest, it enters the second peak season of grape branch growth, and the nutrition made by leaves has three destinations. One is that it keeps growing and the leaves keep growing. Promote winter bud differentiation and reproductive growth. It is nutrient backflow (stored in trees and roots). At this time, secondary growth and winter bud differentiation compete for nutrients. The more prosperous the couple are, the less full the winter buds are. So it is very important to adjust some fertilizers at this time. The pruning time of grapes should be about 15~20 days after fruit picking. The tree 1 has enough time to relieve the wound of fruit picking, and the nutrient accumulation of this tree has begun to increase. Pruning can make trees sprout quickly at this time.

Pruning should be adjusted reasonably to prevent excessive consumption of nutrients in trees. Gently remove the long branches of nuclear disciples, remove appendages, reduce nutrient consumption and promote eggplant maturity. At the same time, prune the vines reasonably, with more thick branches and less weak branches. Overcrowded eggplant, thin and weak eggplant, pests and diseases should be removed as soon as possible. Pruning after harvest should not be too heavy. Otherwise, the branches will mature this year, and winter buds will easily appear, which will easily affect the growth and fruit of plants next year. Generally, leaves are not picked after harvest, and there are fewer buds to keep the branches and leaves vigorous. In the vigorous bud. You can cut off the 5th ~ 6th buds on the first leaf and leave the first two buds as the second fruit to germinate (suitable for some areas and early-maturing varieties). You can cut the first two internodes when picking fruit in winter.

You can remove the object from the workspace page. The branches are thick, and the number of fruit branches is less than this, so they can be trimmed like satin. However, if the floating tip is small or the remaining branches are suitable for fruiting, they should be cut directly from the base to avoid wasting nutrition. Pruning will help to enlarge the crown and adjust the momentum of trees. On the contrary, if the floating tip is small and the main tip is insufficient, you can keep the floating tip and continue to cultivate it to become the branch tip of the fruit in the next spring. Pruning is an important measure in grape cultivation, artificially inducing grape plants, adjusting the contradiction between growth and fruiting, aging and regeneration, and establishing a relatively balanced and unified relationship. Reasonable pruning can achieve good growth, early fruit and good effect. In other words, fruit trees can prolong life, renew and recover, and delay aging.

Pruning is to regulate the movement of water and nutrients in fruit trees and improve their physiological activities. Transforming vegetative growth into reproductive growth. Pruning is not a single pruning, but pruning and other measures to promote local and overall physiological activities. Strengthen the ability of root system to absorb nutrients and water, strengthen the transportation function, keep the tree solid and maintain a bumper harvest every year. Improve ventilation and light transmission conditions, strengthen assimilation and reduce diseases. Pruning can change the direction of branches, remove unnecessary branches, make new branches evenly distributed on the shelf, make full use of space, improve lighting conditions and improve photosynthetic effect. Only on the basis of shaping and pruning, comprehensive use of various cultivation measures can achieve the goal. As the saying goes, in the process of pruning, we should keep learning, carefully observe the pruning reaction of fruit trees, and learn trees with an open mind. Only by carefully observing the reaction after pruning and moving from practice to practice can we better serve agricultural production, change old ideas, establish, invent, create and advance.
