Description

Grape trellis with shed of V + horizontal leaf curtain
Technical Field
The utility model relates to a grape cultivation technical field specifically is a V + horizontal leaf curtain of suitable arid area in the north links canopy grape trellis.
Background
The selection of the grape cultivation frame is very important for the regulation of the tree vigor, and the proper grape frame is beneficial to the regulation of the grape tree body, the formation of the grape yield, the improvement of the fruit quality and labor saving and labor reduction of field management. The main frame type in foreign countries is a shed frame or a hedge frame, and the standard frame type, the single vertical frame type, the single-trunk double-arm or single-arm cultivation and other regular tree types are adopted, the fruit bearing parts are unified, the leaf curtain and the fruit have obvious boundary, and the pesticide spraying management and the mechanical production are facilitated. The simple pruning, the large-scale cultivation, the specialized management, the standardized production and the consistent quality are important characteristics of the foreign advanced grape production countries.
The northern grape cultivation frame mainly comprises an inclined small shed frame and a horizontal shed frame, the inclined small shed frame has the characteristics of good windproof effect, less materials and the like, but the frame surface is short, is inconvenient to manage and mechanically operate, has the defects of poor grape quality uniformity, serious pest and disease damage and the like, and particularly has the problems of coloring of different fruiting parts, inconsistent maturity and the like in the cultivation of large red varieties such as 'new grape trees' by adopting the traditional small shed frame, so that the fruit quality is uneven, the high-quality commercial fruit rate is low, the mature period is delayed and the storage and transportation resistance is reduced. The height of the horizontal trellis is generally more than 180 cm, the trellis surface sinks along with the increase of the load capacity in the growing season of the grapes, and the problems of inconsistent fruit illumination conditions, inconsistent grape quality, difficult coloring of red varieties and inconsistent ripening also exist. The two grape young shoots cultivated in the rack type grow in a crossed and overlapped mode, the shoots need to be picked and trimmed for many times in summer, a grower needs to work at the head, and the labor efficiency is low; the main vines of the grapes need to be twisted by 90 degrees when the grapes are put on the shelf in spring and put on the shelf in autumn, the main vines of the grapes are easy to be twisted, and the labor intensity is increased. In recent years, the labor cost is continuously increased, the production cost is improved, and the economic benefit of fruit growers is seriously reduced. With the development of grape cultivation technology at home and abroad, the market competitiveness of northern grape products is obviously reduced, and how to improve the fruit quality and the mechanization degree and reduce the production cost is an urgent problem to be solved in production.
In recent years, the direct-running horizontal dragon-dry type and horizontal leaf curtain cultivation rack type (CN103120111A: a method suitable for northern grape horizontal and shed frame cultivation) is gradually applied to northern fresh-eating grape cultivation, the cultivation rack promotes the early ripening of fruits, improves the quality of partial varieties of fruits to a certain extent, reduces the trimming amount and the labor intensity of putting down the grapes, is beneficial to mechanical operation, and controls the production cost to a certain extent. However, the cultivation frame is too high in frame surface, the main vines are arranged at a height of 1.80-2.00 meters away from the ground, the labor intensity of putting the cultivation frame on the frame is high, the main vines need to stay fruit branch groups at a position of about 2.50m, the cultivation time of the main vines is long, the difficulty is high, the production time of a vineyard is prolonged, a large number of invalid main vines increase the soil burying amount, and the pier opening and burying costs are increased; secondly, the grape trellis has fruit ears all at the height of 1.80-1.90 m, the height of the young shoots is 2.00 m, the young shoots are bound, managed and managed by facing upwards, the operation is inconvenient and the efficiency is low; most importantly, in northern arid areas, grapes are hot and high in growing season, air humidity is low, illumination is strong, and the grape trellis has the problems of low fruit bearing rate, reduced fruit grain quality, reduced yield, excessively deep coloring of red grape varieties, premature dehydration and shrinkage of fruits, wilting of fruits, short fruiting period and the like due to the fact that the grape trellis is small in fruiting area index, high in inflorescence and high in fruit height and is influenced by adverse climate factors such as high temperature, dry hot air, excessive illumination and the like. It is difficult to produce high-quality commercial fruits with bright red fruit color, large fruit grain mass and moderate sugar-acid ratio, and the good quality of grape varieties cannot be fully excavated.
