Problems solved by technology

[0003] To sum up, the existing problems in the prior art are: the existing grape shaping and pruning methods have insufficient light received by the grape vine body, uneven light and heat, poor fruit coloring, slow rise in sugar content, and low fruit quality, resulting in dwarfing of the tree body. , After the length of the arm is shortened, the growth of the auxiliary shoots of the tree will be increased, the amount of labor will be increased, and the production cost will increase

Embodiment 1

[0034] Under greenhouse conditions, two new shoots are cultivated to form two trunks, which are distributed in a V shape. The widest distance between the two trunks is 1m, and the height of the trunks is 2m, which are respectively the first trunk and the second trunk.

Embodiment 2

[0036]The topping work is carried out at the position of 2m from the first main trunk. After the topping is completed, the auxiliary shoots of the branches are stimulated to germinate. After germination, two auxiliary shoots near the position of 2m are cultivated and tied to the scaffolding on the south side and the north side of the main trunk respectively. On the iron wire, the auxiliary shoot length on the north side is cultivated to 2.5m, and then the first auxiliary shoot is formed.

Embodiment 3

[0038] When the second main trunk grows to the position of 2m, the branches are obliquely tied to the scaffolding wire at the position of 2m, and the branches are extended obliquely to 1.5m for topping. After the topping is completed, the secondary shoots of the branches are stimulated to germinate After germination, cultivate two auxiliary shoots near the position of 1.5m, and tie them to the scaffolding wires on the south and north sides of the main trunk respectively. After the auxiliary shoots on the north side are cultivated to a length of 2.5m, they will be topped to form the second trunk. The first auxiliary shoot, the auxiliary shoot length on the south side is cultivated to 2m, and then the heart is picked to form the second auxiliary shoot of the second trunk.

Abstract

The invention belongs to the technical field of grape renovating, and discloses a greenhouse grape VF-shaped tree and a cultivating method for the same. The greenhouse grape VF-shaped tree consists oftwo trunks, the distances from the two trunks to the ground are 2m, the two trunks are distributed in a V-shaped manner, the widest distance in the V-shaped space is 1 m, two secondary shoots are cultivated on the first trunk, the length of the first secondary shoot is 2.5 m, the length of the second secondary shoot is 2 m, and a high-position single-trunk double-arm-shaped tree is formed by thewhole first trunk; a branch at the position, with the height of 2 m, of the second trunk grows obliquely to one side and pinching is carried out after the length of the branch reaches 1.5 m, and two secondary shoots from north to south are cultivated; the length of the third secondary shoot is 2.5 m, the length of the fourth secondary shoot is 2 m, a fruiting branch from east to west is cultivatedat the position, with the height of 1.5 m, of the second trunk, the length of the fruiting branch is 1 m, the fruiting branch is used for bearing fruits, and thus, the second trunk forms an F-shapedtree; and therefore, the VF-shaped tree is formed finally. By the tree, the problems of poor green grape fruit coloring, slow sugar content rising and low fruit quality can be solved.

Description

technical field [0001] The invention belongs to the technical field of grape trimming, and in particular relates to a greenhouse grape VF tree shape and a cultivation method thereof. Background technique [0002] The existing dwarf "single stem and double arm" tree cultivation, that is, the "single stem" is stable at 0.7-0.8M, the arm length is 0.5-0.6M, and the auxiliary shoots of both arms are stable at 1.5-1.8M. Existing technology 1: a facility The grape shaping and pruning method creates a "single stem with two arms" tree shape through tree dwarfing and low pruning. This method of shaping the "single stem and double arms" tree shape by dwarfing the tree body and low pruning has defects. Since the greenhouse space is in a low-light environment, and the grape itself is a light-loving plant, the low-slung single-stem double-arm will cause the vine to receive insufficient light and uneven light and heat, resulting in poor fruit coloring, slow rise in sugar content, and low...
