Grapevine winter pruning four notes
Determine the number of leaves left to shoot when pruning should first determine the yield, and then determine the number of shoots left in the bud left. In practice, the number of shoots per plant should be determined according to the size of the plane, the type of pruning and the tree potential. The 1.2m frame can accommodate about 15 new shoots, and about 15cm of new shoots will be left when the frame of the hedgerow vertically ties the new shoots. In the full fruit period, the amount of shoots left for winter shearing is 2 times the amount of new shoots required to cover the surface. Strive to be strong but not prosperous, reasonable load, air and light. When distinguishing the main side of the winter vine, it must first distinguish between the main vine and the side vines, and then select the vines from the main side vines as the new result of the vines. The two mothers should not be less than 30 centimeters apart. Pruning should be done from the bottom up, from the middle to the sides, to remove pests, branches, overlapping branches, overlapping branches, cross branches, long branches of greed young people, and old and weak vines. When leaving the grapevine in the cold-proof zone buried in the ground, it should reserve 10% to 20% of the branches as a preparatory branch to compensate for the losses caused by buried soil, shelves, and frost damage. Because of the loose tissue of the grapevine, the water loss is fast, and there is often a small amount of dryness under the cut. In order to protect the cut-off buds, they should be cut at 3 to 5 cm on the cut. When the festival is too short, it can be cut in the middle of a gap between the buds before the cut. At the same time, it should be noted that the kerf should not be too close to the vine so as not to shrink the wound and affect the nutrient delivery. The cut lengths of the long, medium, and short methods for flexible trimming of grapes have a certain degree of flexibility, and they cannot be rigidly applied. Generally should be based on the strength of the mother branches, thickness and flexible operation. Within the scope of the prescribed number of buds, it should be stout and substantial. The mother branch can be maintained for a long period of time, and the weak and less mature mother branch should be appropriately short-cut.
