摘要

A trial was conducted to determine the effect of water deficit at tuber initiation of potato regulated with mulched drip irrigation on tuber yield and efficiency of water use in an arid environment. The results indicated that tuber yield of potato was significantly (p<0.05) reduced by 12.7% ~23.2% under water deficits compared to full irrigation while potato water use efficiency and irrigation water use efficiency were significantly increased by 10.6% -14.2% and 9.4%~ 10.6% respectively, but no difference (p>0.05) was found both in water use efficiency and irrigation water use efficiency between water deficit treatments. Therefore, soil water deficit at tuber initiation regulated with mulched drip irrigation could be used to effectively improve potato water use efficiency and irrigation water use efficiency in an arid environment.
