A cross double T-shaped vine shape and its pruning method

Abstract

The invention discloses a cross double-T-shaped grape tree form and a pruning method thereof. The grape tree form comprises a main vine (1), two side vines (2), fruiting branches (3), developmental branches (4), fruiting canes (5) and updating branches (6), wherein the height of the main vine (1) is 1.4-1.5m, and the main vine is perpendicular to the ground; the two side vines (2) are positioned at the top end of the main vine (1), and respectively and horizontally extend to two sides along the row direction, and the length of each side vine (2) is 1.0-1.5m; the fruiting branches (3) and the developmental branches (4) are arrayed in parallel at intervals of 15-20cm, are perpendicular to the side vines (2), and extend along the horizontal direction. The tree form is particularly suitable for simple small trellis rain-sheltering cultivation of southern vitis vinifera. Compared with the prior art, the cross double-T-shaped grape tree form is good in rain-sheltering effect, high in fruit quality, low in investment cost and high in yield, is capable of effectively reducing diseases and is capable of effectively sheltering rain without a greenhouse.

Description

technical field [0001] The invention relates to a grapevine shape, in particular to a cross double T-shaped grapevine shape and a pruning method thereof. Background technique [0002] Eurasian grape varieties such as 'Wanhong', 'Beauty Finger', 'Golden Finger', 'Royal Autumn', 'Kraison Seedless' and 'Sentani Seedless' have good quality, sweet flavor and storage resistance, etc. Advantages, favored by the majority of consumers. Generally, the seedlings are planted in the first year, and the income can be put into production the following year. In the arid and rainless areas of the northwest, the Eurasian grapes can produce 1,500-2,000 kilograms of fresh fruit per mu during the fruiting period, the output value per mu is 30,000 to 40,000 yuan, the net income is more than 10,000 yuan, and the economic benefit is more than twice that of cultivating European and American hybrid grapes. . However, in most areas of southern my country, due to the high temperature and humidity, t...

Problems solved by technology

However, if the "middle shoot" and "long shoot" are pruned year after year, it will not only cause dense branches in the rain shelter facilities, poor ventilation and light transmission, serious grape diseases, low fruit yield and poor quality, but also cause the fruiting parts to move outward rapidly. , It is impossible to implement simple small arch sheds for rain-proof cultivation, only to increase more investment and build plastic greenhouses for rain-proof cultivation
