Abstract: 【Objective】 To study the effect of inclined dragon trunk shaping (V+ horizontal) leaf curtain cultivation mode on the culster micro-environment, fruit quality, powdery mildew occurrence and economic benefits of table grapes in Turpan area in the hope of providing reference for high-quality and efficient cultivation of table grapes in this producing region. 【Method】 The Xinyu grape in Turpan was taken as the test material, inclined dragon trunk shaping (V+ horizontal) leaf curtain cultivation adopted, and the traditional small trellis cultivation used as a control, the culster micro-environment during fruit development under the two cultivation modes were compared to find out the differences in fruit quality, powdery mildew occurrence and economic benefits during harvest. 【Results】 The results showed that compared with traditional small trellis cultivation, inclined dragon trunk shaping (V+ horizontal) leaf curtain cultivation improved the light and heat levels in the culster micro-environment during the development of Xinyu grape, and the average temperature difference increased by 2.37℃.The average daily total radiation was 1.47 times that of the small trellis, which reduced the surface humidity and high humidity ratio of the fruit, and improved the micro-environment of culster; berry mass, soluble solid content and anthocyanins of skin content increased by 32.09%,31.04% and 171.43% respectively, fruit ripening happened 10 days earlier, coloured ripeness was good, fruit quality, storage and commodity rate increased obviously, incidence and disease index of powdery mildew were reduced by 59.49 % and 60.85 % respectively, the simple and efficient cultivation mode reduced the production cost and increased the economic benefit of a unit of area by 86.50 %. 【Conclusion】 The 'Xinyu' grapes in Turpan region which adopts inclined dragon trunk shaping (V+ horizontal) leaf curtain cultivation achieves the goal of high-quality and high-efficiency cultivation.
