图5 马铃薯生育期耗水与产量要素的相关关系 Ⅰ、Ⅱ、Ⅲ、Ⅳ分别指代苗期、块茎形成期、块茎膨大期、淀粉积累期；TY：产量；LR：大薯率；MR：中薯率；SR：小薯率；CR：商品薯率。“*”和“**”分别表示P < 0.05和P < 0.01水平显著相关。

Fig.5 Correlation between water consumption and yield factors in potato growth stage Ⅰ, Ⅱ, Ⅲ, Ⅳ refer to seedling stage, tuber formation stage, tuber bulking stage, starch accumulation stage, respectively; TY: the output; LR: the percentage of large potato; MR: medium potato percentage; SR: the percentage of small potato; CR: commercial potato rate.“*”and“**”indicated significant correlation between P < 0.05 and P < 0.01 levels, respectively.
