The results showed that the grapes with shoot-fruit ratio of 1∶ 1 had the highest soluble solid content, vitamin C content and grapevine storage nutrient. Based on the comprehensive analysis, the shoot-fruit ratio of 1∶ 1 was the optimized load for Summer Black grapes in Tai an of Shandong Province, and the yield was 1 179.37-1 288.63 kg per 667 m^2.展开更多
