The problem that should be paid attention to during the winter pruning of red grape
The purpose of winter pruning is to adjust the relationship between tree growth and results on the basis of plastic surgery, so that the distribution of the branches and vines is uniform, the amount of fruit is moderate, and the result is prevented from moving outwards, and the tree body is renewed and rejuvenated, which promotes high quality, high yield and stable yield of grapes. purpose. Winter pruning should pay attention to the problem: (1) Thickness of the cut: When the thickness of the red twig is 0.8-1 cm, the flower buds are formed well, and the branches of the branches are too fine (below 0.6 cm) and overly thick (1.2 cm or more).

(3) Accidental injury: During pruning, try to avoid artificially causing excessive accidental wounds, avoid damage to the tree body, and damage the main vine and reserve branches; when man-pressing, avoid artificial damage to the main vine, side vine and fruiting branch. . (4) Storage seed strips: If seedlings are needed, the strips should be selected while trimming and timely (on the same day). (5) Buried soil and cold protection: The pruning time should not be dragged too long to avoid the loss of nutrients in the branches. It should be trimmed at any time, pressed at any time, and buried at any time. It is advisable to bury the soil with mechanical burial, and the amount of burial should be large and thick. (6) Watering winter irrigation: watering winter irrigation should be completed before the grape is trimmed, and the water should be poured through the winter irrigation.
