A Retrofit Technology for Retraction and Strengthening Frame

Abstract

This application discloses a retraction-promoting frame transformation technology, which includes the following steps: S1, pruning in spring, cutting off the newly grown main trunk at 1.2 meters to form the main vine, and pruning at 1.1 meters on the grape support Arrange the second iron wire, if the height of the main trunk is not higher than the second iron wire, all pruning is performed at a distance of 20 cm from the ground to form a quasi-main vine; S2, the branches are removed in the inflorescence stage, and only the inflorescence and the base are left on the main vine facing south And the thick bar in the north direction, all the weak buds and other branches are erased; S3, select two thick branches at the base of the quasi-main vine. When the main vine is cultivated in the second year, the height of the quasi-main vine reaches 1.2-1.4 meters time topping. The advantages of the present invention are: the output of the current year is still 40-50%, and the output of the second year of transformation is also 40-50%, and the normal output can be restored in the third year, which saves time for the transformation of the old Dulongman vineyard, and The grape yield will not be greatly affected, and it is worth using in the transformation of large-scale 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
