Three different pumpkin rootstocks（Lifting Rootstock, Shengzhen 1 and Xinli 3） were used to treat Shengchun 8, Jinchun 39 and Vegetable Chunxin exceeding cucumber with grafting combinations. The effects of different rootstock grafting combinations on plant height, stem diameter, yield, chlorophyll content, soluble sugar content and protein content of cucumber were studied with self-rooted plants as control. The results showed that plant height,stem diameter, leaf area and yield per plant of the grafted varieties were generally higher than those of the control,soluble sugar content was higher than that of the control. In contrast, Xinli 3 was the best grafted stock. The grafting combination of Shengchun 8 and Xinli 3 can be preferentially selected in production.
