Abstract: 【Objective】 In this article, effects of canopy type and plant-derived nutrient solution on the growth and berry quality of Cabernet Sauvignon with '厂' shape training structure were studied in the hope of providing a theoretical basis for choosing management standards for wine grape in the producing area near northern piedmonts of Tianshan mountains.【Method】Taking 7a old "厂" tree shape "Cabernet Sauvignon" grape as the research object, four experimental treatments were set up: hedgerow leaf curtain, hedge wall leaf curtain + nutrient solution, V-shaped leaf curtain, V-shaped leaf curtain + nutrient solution. We investigated the temperature, humidity index at fruit expanding, colour-changed and mature periods; and the index of PAR daily variation regularity, leaf quality and photosynthetic capacity at different places of canopy were detected at colour-changed period; the fruit quality index such as weight of cluster and berry, pericarp weight /berry weight, number of seed, loose degree of cluster, soluble solid, titratable acid, total flavonoids and polyphenol were detected during the mature period.【Result】The light condition of leaf curtain population could be improved, and the temperature day d value around berry increased with V canopy type. And this canopy cluster used, the fruit ears became looser, and soluble solid, titratable acid, total flavonoids and polyphenol contents in berry were increased. 【Conclusion】The leaf chlorophyll, soluble protein content and photosynthetic capacity were increased with plant-derived nutrient solution treatment, and physiological activity of leaf were improved. And both the index of pericarp weight /berry weight, number of seed, soluble solid, titratable acid, total flavonoids and polyphenol contents were increased significantly. Wine-making quality of berry was improved with both V canopy and plant-derived nutrient solution treatment.
