Grape tree form suitable for a simple single-span arched shed and construction method

Abstract

The invention discloses a grape tree form suitable for a simple single-span arched shed and a construction method. The grape tree form is provided with a vertical trunk, wherein a first main vine anda second main vine which reversely extend in the length direction of a ridge are cultivated at the upper end of the grape tree form; a third main vine perpendicular to the main vine is cultivated at the positions, close to the vertical trunk, of the first main vine or the second main vine, wherein the third main vine obliquely extends upwards and then horizontally extends in the width direction ofridges; first fruiting branches are cultivated on the two sides of the first main vine and the two sides of the second main vine at intervals, and V-shaped leaf curtains are cultivated on the two sides of the first fruiting branches through stay wires; and second fruiting branches are cultivated on the two sides of the third main vine at intervals, and the second fruiting branches on the two sides reversely and horizontally extend and are cultivated on a flat canopy frame in the length direction of the ridge to form a horizontal leaf curtain. The frame is concise in shape, formed in one year,suitable for medium and short slight pruned grape varieties; and by virtue of the V-shaped leaf curtains and horizontal leaf curtains, the tree from is high in photosynthetic utilization rate, good in ventilation and light transmission, convenient to operate mechanically, capable of achieving spatial three-dimensional distribution of fruiting parts and capable of enhancing the sightseeing and picking experience feeling.

Description

technical field [0001] The invention relates to the technical field of viticulture, in particular to a vine shape suitable for a simple single-span shed and a construction method. Background technique [0002] The rain shelter cultivation of simple single-span arch shed has the characteristics of low facility cost, good rain shelter effect and wide application range. At present, the 'V' shape and 'T' shape of the fence are mostly used, or the dragon stem shape of the simple horizontal scaffolding is cultivated. Simple single-story arch shed A generally has a width of 8 m and a top height of 2.5 to 3 m. It adopts the "V" and "T" cultivation methods of the fence. If three rows are planted, the row spacing is narrow, and the inside of the shed is closed and ventilated. The light is poor, the pests and diseases are serious, which is not conducive to mechanized operation, and the experience of sightseeing and picking is not high; if two rows are planted, the land utilization rat...

Problems solved by technology

[0004] The patent application number is 201510663002.3, a vine shape and its construction method. The technical feature is to cultivate an upright trunk, and two main vines are cultivated separately on the trunk; then the upright trunk is transformed into a horizontal extension to continue to form a horizontal trunk. Two main vines grow on the left and right at the top of the horizontal trunk. The four main vines are at the same level, which eases the tree vigor of the vigorously growing variety to a certain extent, reduces the workload of summer management, and also facilitates the implementation of mechanized operations and sightseeing in the vineyard. However, this technology needs two years to complete the cultivation of the tree shape, and the time to obtain benefits is relatively late, and the tree shape cultivation requires high technology, especially the technical requirements for the renewal of the result parts, which is easy to cause disordered branches and damage to the branches. Influenced by the gravity of fruit ears, the frame surface sinks, so it is not suitable for simple single-story arch sheds for rain-proof cultivation and sightseeing picking
