Crystal grape slope TU shape pruning technology

Abstract

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.

Description

technical field [0001] The invention relates to a TU-shaped shaping and pruning technology for crystal grape slopes, and belongs to the technical field of grape shaping and pruning. Background technique [0002] Grape is widely planted as a kind of fruit that people like very much. Most of the existing planting techniques are planting techniques adapted to T-shaped grape racks, and some planting techniques are also evolved on the basis of this planting technique. These planting techniques are more suitable for planting on flat land in plain areas. However, this planting technology is not very suitable in southern China, especially in the Yunnan-Guizhou Plateau, because the large-scale flat land in the Yunnan-Guizhou Plateau is relatively small and most of it is slope land. The frame is tilted to one side. If the existing T-shaped grape frame planting technology is used on the slope, there will be the following problems: 1. If the horizontal gradient line spacing is increase...

Problems solved by technology

However, this planting technology is not very suitable in southern China, especially in the Yunnan-Guizhou Plateau, because the large-scale flat land in the Yunnan-Guizhou Plateau is relatively small and most of it is slope land. The frame is tilted to one side. If the existing T-shaped grape frame planting technology is used on the slope, there will be the following problems: 1. If the horizontal gradient line spacing is increased and the row spacing between the horizontal gradients is reduced for planting, after 3 years on the shelf, Due to the influence of the grape's growth habit towards the top, the fruiting branches growing downward in the T-shape become weak, and the fruiting branches growing upwards grow too strong, overlapping with the T-shaped trunk in the previous row too much, and the whole orchard tree shape is chaotic; 2. If the horizontal gradient line spacing is increased and the row spacing between the horizontal gradients is not reduced for planting, after 3 years on the shelf, due to the influence of the grape's upward growth habit, the fruit branches growing downward
