Abstract

The utility model discloses a dwarfing both arms U type grape trellis, including a plurality of supports and the threadlike thing of connecting each support and supporting pruning technique, support one-to-one, vertical fixation are subaerial, each support is connected to threadlike level, the threadlike thing includes first threadlike thing, second threadlike thing, third threadlike thing. The utility model discloses grape trellis has reached the effect that grape plant height reduced and the tree body is miniaturized on the basis of ensureing grape output and quality, not only makes the vineyard easily reduce the management, has improved the grape productivity effect moreover, is a fine selection of sunlight greenhouse grape forcing culture in the north. In a word, the dwarfing double-arm U-shaped grape trellis is a cultivation trellis which integrates beauty, labor saving and high efficiency and is convenient for mechanical operation.

Description

Dwarfing double-arm U-shaped grape trellis

Technical Field

The utility model belongs to the technical field of grape is planted, concretely relates to be suitable for dwarfing both arms U type grape trellis of northern regional sunlight greenhouse grape forcing culture.

Background

The grapes are one of the widest-planted fruit tree species with the highest yield in the world. The yield and quality of grapes are closely related to not only variety and natural conditions, but also the content and level of cultivation management. Along with the popularization of grape facility cultivation, the quality and benefit of grape fruits are better improved. The grapes cultivated in the sunlight greenhouse have the advantages of early maturity, early marketing, less plant diseases and insect pests, high yield and the like, and the selection and popularization of the proper sunlight greenhouse grape trellis has important significance for exerting the advantages of sunlight greenhouse rain sheltering, heat preservation and the like. The grapes are vine fruit trees, and usually need to be supported by a support for field planting and cultivation, and are combined with pruning to form a tree shape which is easy to ventilate, light-permeable and convenient to manage. The two sides of the hedge surfaces of the hedge frame are exposed to light, the hedge surfaces of the hedge frame are provided with more leaf surfaces, the mechanical management is easy, and the hedge frame is divided into a single-arm hedge frame and a double-arm hedge frame, wherein the double-arm hedge frame has obvious yield advantage compared with the single-arm hedge frame, but the traditional double-arm hedge frame is high, the management workload is large, the requirement on a sunlight greenhouse is high, a certain height is required, the manufacturing cost is high, the temperature is difficult to guarantee, and the early promotion effect.

The Y-shaped frame is one of grape frames widely used in the world at present, the height of the frame is about 1.8m generally, the width of a crosspiece is 80-120cm, grape branches are unfolded, the lighting and ventilation effects are guaranteed, and the incidence rate of diseases is low. In the north, because the temperature is too low in winter, the process that grapes must pass through is buried in soil and is also a labor-consuming farming work. The common grape trellis support is too high and has more branches, so that the workload of burying soil is huge, and the available mechanization degree is low due to distortion of grape trellis burying soil all the year round. Based on the method, a grape Y-shaped frame is transformed and tested for 3 years continuously, a dwarfing U-shaped frame is developed, the height of a trunk is reduced, a main vine of a base part is horizontally opened, a new shoot vertically grows, the illumination utilization rate is greatly improved, the mechanical operation space is enlarged, the number of branches is small, and the labor force is greatly saved due to the reduction of the trunk.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a dwarfing double-arm U-shaped grape trellis which is beautiful, labor-saving, efficient, convenient for mechanized operation and easy for burying soil and preventing cold.

The technical scheme is as follows: a dwarfing double-arm U-shaped grape trellis comprises a plurality of supports and wires connected with the supports, wherein the supports are in one-to-one correspondence and are vertically fixed on the ground, the wires are horizontally connected with the supports, and the wires comprise a first wire, a second wire and a third wire.

Preferably, the thickness is 75m or 1.40 m.

Preferably, the support is a stainless steel column.

Preferably, the distance between the brackets is 0.7 m.

Preferably, the first, second and third wires are galvanized steel wires.

The height of the support is 2.30 meters, the underground is buried by 0.60 meters, and the ground part is 1.70 meters.

Has the advantages that:

the utility model has the advantages that: the utility model discloses improved the sight and the harvesting nature in vineyard on the basis of ensureing grape output, be sightseeing garden and a fine selection of picking garden grape trellis type, in addition, the usable mechanization degree of dwarfing cultivation strengthens, has saved the labour greatly. In a word, the dwarfing double-arm U-shaped grape trellis is a cultivation trellis which integrates beauty, labor saving and high efficiency and is convenient for mechanical operation.

fig. 2 is a schematic diagram of the dwarfing double-arm U-shaped grape trellis young sprout growth in the embodiment of the present invention.

Detailed Description

In FIGS. 1 to 2, 1 and 2 are first threads, 3 and 4 are second threads, 5 and 6 are third threads, and 7 and 8 are scaffolds.

As shown in fig. 1, the dwarfing dual-arm U-shaped grape trellis of the embodiment of the present invention comprises four stainless steel columns spaced 2.5m apart from each other and arranged on both sides of the trellis and six linear members connecting the supports, wherein the stainless steel columns are fixed on the ground perpendicular to the ground, and the parts of the stainless steel columns are buried underground. In FIG. 2 the

lines

5 and 6 are 0.4 m from the ground for vine attachment; and

lines

1 and 2, 3 and 4, 5 and 6 are 1.40, 0.75 and 0.4 meters away from the ground for binding vines by grapes. The supports are regularly arranged in the front-back direction and the left-right direction, and the

threads

1, 2, 3, 4, 5 and 6 between the adjacent supports form a dwarfing double-arm U-shaped grape trellis grape tree shape.

In this embodiment, as shown in fig. 1, the height of the cement column is 2.80 m, and the cement column is buried under the ground by 0.60 m, and the six

wires

1, 2, 3, 4, 5, and 6 shown in fig. 2 are galvanized steel wires, and the heights thereof are 1.4, 0.75, 0.4, and 0.4 m, respectively.

As shown in fig. 1 and 2, the planting method comprises the following steps: selecting annual robust grape seedlings, carrying out pinching treatment at a position 30-40cm away from the seedling base, fixing to dry, then sending out two new shoots, horizontally binding along a position vertical to a galvanized steel wire, then leaving about 12 leaves on each new shoot for pinching, and leaving 4-5 annual branch short tips for pruning in winter as shown in figure 1. The method is adopted every year. In the grape climbing process, the base of the main vine is adjusted to be horizontally opened, the main vine rises vertically, the base is recutted and retracted every year, and the illumination utilization rate is realized to the maximum extent under the condition of ensuring the yield.
