Problems solved by technology
[0003] There are the following defects in the grape vine shape shaping method: (1) in the dormant season, the angle of the base of the grape vine is adjusted when the pressure is pressed down before the burying operation after autumn and the early budding is lifted in spring. The moisture content of the vines has been reduced, the texture is hard and brittle, and it is easy to break or suffer internal injuries; (2) The angle is gradually adjusted by pressing down over many years, and the forming and curing are slow. In the case of thickening and then forcibly pressing down, the base of the tree body will be seriously injured due to excavation and burial operations.

Embodiment 1
[0040] In 2017, in Beizhangdai Village, Machangying Town, Pinggu District, Beijing, the grape variety was 'Ruidu Hongyu', and the shaping method was a forward horizontal dragon trunk shape. Last year, the spreading long shoots were all cut to a length of more than 2.0 meters. This year, the one-time bunching of the base angle of the main vines in the buried area, the cultivation of the long main vines and the early results have been completed.
[0041] Specific steps are as follows:
[0042] A. In the growing season of the second year after planting, according to the length of the main spreading long shoot last year, the cut length is mostly greater than 2.0 meters, and the following methods are selected:
[0043] A1. When the effective length of the base of the main vine cut in the previous year is sufficient to be tied to the first lead wire, the new shoots grow to 10-15 cm at the beginning of the growing season, and the main vine is 20-30 cm from the base. pull it down unt...

The present invention relates to the field of fruit tree cultivation, and provides a method for adjusting the angle of the base of the grape main vine in the northern soil-buried cultivation area, specifically: A. During the growing season of the second or third year after planting, the main vine is moved from the base 20 At ‑30 cm, pull it down until it is parallel to the ground and then fix it. The front end of the main vine is slowly lifted and transitioned to extend horizontally and forward to draw and tie the frame, and the bundle is in place at one time; B. There is no need to press down on the base of the main vine when buried in winter; C. 1. When putting on the shelves in the early stage of germination every spring, the main vine is lifted to the level and extended forward smoothly, so as to avoid the formation of right-angle bends of the main vine. The method of the present invention makes the main tendril of the grape vine complete the beam shape within one year, and at the same time cultivates sufficiently long extended shoots as the main tendril in the future, greatly improving the effective utilization rate of the growth of branches; Different degrees of damage to the tree body at the base of the vine ensure that the grapes in the buried cultivation area have a stable and balanced perennial tree structure, which provides the most basic tree body guarantee for high-quality cultivation.
Description
technical field [0001] The invention belongs to the field of fruit tree cultivation, and in particular relates to a method for adjusting the base angle of grape main vines in the northern soil-buried cultivation area. Background technique [0002] The grape cultivation in the buried soil area in the north usually uses the dragon trunk shape shaping. In the dragon stem shape shaping, in order to meet the convenience of the buried soil operation and take into account the needs of early temporary results, the angle of the base of the main vine of the grape vine is gradually completed by the downward beam shape every year. , Carry out pressing and lifting operations before the annual post-autumn burying operation and the early spring germination stage. [0003] There are the following defects in the grape vine shape shaping method: (1) in the dormant season, the angle of the base of the grape vine is adjusted when the pressure is pressed down before the burying operation after a...
