The invention discloses a
crystal grape slope TU shape
pruning technology. Seedlings in the current year are planted, and short
seedling segments are reserved. After
sprouting, two young sprouts are selected and remained; after the two sprouts grow up, one strong
branch serves as the main
vine and is guided to spread onto a trellis through an inserted rod in a stretched mode, the weak
branch is removed, pinching is carried out on the main
vine after the main
vine grows up to form a
trunk, two accessory buds are cultivated on two upper knots and used as main branches after pinching, the other accessory buds are removed, and grape tendrils are removed too. The two main branches grow towards the two sides in the horizontal direction of a slope, then are guided upwards along the slope in the direction perpendicular to the horizontal line of the slope, are subjected to binding cultivation, and then are subjected to pinching. Secondary accessory buds growing at knot axils of the main branches are all reserved, leaf remaining and pinching are carried out on all the secondary accessory buds, and the secondary accessory buds are bound.
Crystal grape branches and tendrils in a mountainous region do not overlap or overlap slightly after
pruning, the steps of
pruning,
branch binding, pinching,
bud removing, bagging, picking and the like are simple and fast, labor and time are saved, tree vigor is strong, the tree form is stable and standard, fruit clusters are large and orderly, products are high in commodity, and the yield is easy to control.
