Problems solved by technology

[0005] The technical problem to be solved by the present invention is that in order to overcome the unstable yield and quality of grapes in the prior art, it is inconvenient to renew fruit branches, and with the aging of the tree, the fruit parts move outwards, and it is easy to produce the defects of bare areas. A T-shaped vine shape and its forming method

Embodiment 1

[0053] Select European and American Sunshine Rose grapes with moderate growth but high flowering nodes, and prune them in a T-shaped vine shape under the cultivation of a flat scaffold.

[0054] 1. This embodiment provides a T-shaped vine of Sunshine Rose grapes, including a 1.8m upright trunk 1, and two main vines 21, 22 growing oppositely from the top of the trunk at an angle of 100° to the trunk , the sum of the lengths of the two main vines 21 and 22 is 5 meters, and the overall tree forms a T-shape; the main vines 21 and 22 each have 3 compound fruiting branch groups 3, and 6 compound fruiting branches on the two main vines Group 3 and the main vine 21 and 22 form a double "king" shape; the distance between two adjacent composite result branch groups on each main vine is 80cm, and the distance between the adjacent two compound result branch groups at the top of the trunk is 60cm, the total length of each compound fruiting branch group is 2.5m, each compound fruiting branc...

Embodiment 2-4

[0069] In Shanghai Malu Grape Park, Malu Grape Research Institute, Malu Grape Development Co., Ltd. and other bases, experiments were carried out on Xiahei, Kyoho, Miguang and other varieties. The selection, planting and annual pruning of seedlings were the same as in Example 1.

[0070] Wherein the yield per mu of the summer black of embodiment 2 is 500~600kg in the second year, and the yield per mu from the third year is 1200~1350kg, and the high-quality fruit rate is 92~95%;

[0071] The yield per mu of Kyoho of Example 3 in the second year is 550~600kg, and the yield per mu from the third year is 1400~1500kg, and the high-quality fruit rate is 92~95%;

[0072] The Miguang of Example 4 has an yield per mu of 450-550kg in the second year, and an annual yield of 1200-1400kg from the third year, and the high-quality fruit rate is 92-95%.

[0073] The above experimental data shows that the tree shape of the present invention has the advantages of group shaping, stabilizing the ...

Abstract

The invention discloses a T-shaped grape tree shape and a forming method thereof. The tree shape comprises a 1.7-1.8 meters vertical trunk and two main vines which grow reversely from the top of the trunk to form an included angle of 90-110 degrees with the trunk, wherein the whole tree shape is T-shaped; six composite fruiting branch groups are arranged on the two main vines and are perpendicularto the two main vines; each composite fruiting branch group comprises two composite fruiting branch sets; each composite fruiting branch set comprises a main vines secondary tip, a first-generation fruiting branch set and two second-generation fruiting branch sets; and each fruiting branch set comprises a medium tip fruiting branch and a short tip fruiting branch. By the adoption of the T-shapedgrape tree shape, extension and growth of grape branches can be positioned, oriented and shaped, fruiting branches are convenient to regenerate, bald areas are not easy to generate, and relative stability of quality and yield of grapes is guaranteed.

Description

technical field [0001] The invention relates to a T-shaped vine shape and a forming method thereof. Background technique [0002] Grape pruning is an important technical link in viticulture management. It can balance the vegetative growth and reproductive growth of the tree, and improve the yield and quality of fruit. In the production of grapes in the south, because there is no need to bury the soil for the winter, "T"-shaped, "H"-shaped or dragon-shaped tree shapes in flat scaffolding are often used. These tree shapes have a single trunk, clear leaf curtains, and neat fruiting positions. Consistent, simple technical operation, suitable for mechanized operations. At present, short shoot pruning or mixed short shoot pruning is mostly used in winter pruning, but short shoot pruning is likely to lead to unstable yield and quality of varieties with irregular germination, poor flower bud differentiation or unstable flower formation. The short shoots are renewed every year, and ...
