Frame type retracting and strong-branch-promoting transformation technology

Abstract

The invention discloses a frame type retracting and strong-branch-promoting transformation technology. The technology comprises the following steps: S1, conducting trimming in spring, namely cutting off the parts, longer than 1.2 m, of newly grown trunks to form main vines, arranging second iron wires at places, with height of 1.1 m, of grape supports, and trimming all trunks which are not higherthan the second iron wires and are 20 cm away from the ground to form quasi-main vines; S2, removing branches in an inflorescence stage, wherein only inflorescences and thick and strong branches withbases facing south and north are reserved on the main vines, and weak buds and other branches are completely erased; and S3, selecting and reserving two thick and strong branches at the base of the quasi-main vine, and carrying out pinching when the height of the quasi-main vines reaches 1.2-1.4 m in the second year of main vine culture. The technology has the advantages that the yield of grapes in the current year is still 40-50%, the yield of grapes in the second year is also 40-50% after transformation, and normal yield can be recovered in the third year, so time is saved for transformationof a single-dragon-vine old vineyard, the grape yield is not greatly affected, and the technology is worthy of application to transformation of large-area old vineyards.

Description

technical field [0001] The invention relates to the technical field of grape planting, in particular to a technique for transforming a retraction-promoting frame type. Background technique [0002] With the improvement of national income level and more emphasis on physical health, more and more consumers prefer wine. This trend has gradually formed among young people. In developed regions, wine will increasingly enter family consumption, and consumers More pursuit of high-quality petty bourgeois sentiment and quality of life. [0003] Grapes are perennial vine fruit trees, which need to be erected to maintain a certain space and fruit shape and obtain higher yields. They must be erected in the first year and cannot be climbed smoothly, so they need to be grown with cloth frames. Take dragon pearl as an example, due to the characteristics of the snake dragon pearl variety, the tree vigor is relatively vigorous.

Problems solved by technology

[0003] Grapes are perennial vine fruit trees, which need to be erected to maintain a certain space and fruit shape and obtain higher yields. They must be erected in the first year and cannot be climbed smoothly, so they need to be grown with cloth frames. Take dragon pearl as an example, due to the characteristics of the snake dragon pearl variety, the tree vigor is relatively vigorous. If a new shoot is not controlled during the planting process, it will grow faster, and it can branch many times, and the number of branches (secondary shoots) can reach about 10 times. If the management is not timely, it is easy to form canopy canopy on the shelf surface, the ventilation and light transmission conditions will deteriorate, the fruiting mother branches at the base of the main vine will weaken and die, and the fruiting part will move upwards, and the grapes must grow on the limited shelf surface. In order to control the tree vigor and achieve the goal of transformation while taking into account the output of the year, we propose a retrofit technology for retracting and strengthening the frame to solve the above problems
