A double-flat trellis suitable for burying grapes in cold-proof areas and a method for grape cultivation

Abstract

The invention discloses a dual-parallelism grape canopy frame and a grape cultivation method suitable for a soil-burying cold-proof area. The canopy frame comprises two or more lines of stand columns which are arranged at intervals, a cross bar is arranged on each stand column, first main vine supports are connected among the cross bars, second main vine supports are connected between the upper portions of every two adjacent stand columns, transverse bars are connected between every two adjacent lines of stand columns, and fruiting branch supports are connected among the transverse bars. The invention further discloses the grape cultivation method by means of the dual-parallelism grape canopy frame suitable for the soil-burying cold-proof area. The dual-parallelism canopy frame is of a double-layer frame surface structure, main grape vines and fruiting branches are located on a main vine frame surface and a fruiting branch frame surface which are parallel to each other respectively, light resources can be sufficiently utilized, the amount of branch tip overlapping is reduced, fruit color can be uniform, thereby the grape output is raised, grape quality is improved, and wide practicability and higher economic benefits are achieved.

Description

technical field [0001] The invention relates to the field of viticulture, in particular to a double-flat scaffold suitable for burying grapes in cold-proof areas and a method for viticulture. Background technique [0002] For the cultivation of grapes in the northern cold-proof area, before winter comes, the grape branches and vines are pulled off the shelf surface and placed in the planting ditch, buried in moist soil for the winter, and the grape branches and vines are dug out of the planting ditch in the next spring and tied to the shelf surface. In general, the scaffolds currently used for cultivation are mainly small scaffolds and horizontal continuous scaffolds. Most of the main vines or single vines are vertically placed on the shelves and then tied perpendicular to the row of viticulture.

[0002] For the cultivation of grapes in the northern cold-proof area, before winter comes, the grape branches and vines are pulled off the shelf surface and placed in the planting ditch, buried in moist soil for the winter, and the grape branches and vines are dug out of the planting ditch in the next spring and tied to the shelf surface. In general, the scaffolds currently used for cultivation are mainly small scaffolds and horizontal continuous scaffolds. Most of the main vines or single vines are vertically placed on the shelves and then tied perpendicular to the row of viticulture. Since there is only one binding at the top of the root column of the scaffold The steel wires of the old vines, the old vines repeat too much, and the old vines need to be cut off on a regular basis or the vines are thinned. At the same time, the branches overlap more, the light conditions and nutritional conditions are inconsistent, and the fruit coloring maturity is not uniform, which affects the yield. and quality

[0003] The main vine and the fruiting branch of the common scaffolding are located on the same level, with little or no drop, and it is easy to form closed branches and leaves, so that the base of the fruiting branch 1-3 buds are covered with each other, affecting the flower bud differentiation and yield in the coming year

In addition, the frame surface of ordinary even scaffolding is generally higher than 2m. As a result, the height of the branch group is too high, and it is difficult to manually put the new shoots on the shelves. In summer, the new shoots need to be topped and trimmed several times, which is labor-intensive and easily sprains the branches.

Due to the low surface of the traditional small scaffolding, mechanized operation cannot be realized, and manual operation is also inconvenient

The existing grapes adopt the traditional small trellis or even trellise cultivation mode, which has many defects and deficiencies
