摘要
内蒙古是我国马铃薯的主产区,但是单产却低于全国平均水平,其中水资源短缺和用水技术措施落后是其主要原因。对当地马铃薯水分利用的现状及问题进行了深入剖析,并提出了针对雨养马铃薯的"集蓄保用"和灌溉马铃薯的"3R技术"指导方针,为当地马铃薯持续高产和水分高效利用提供参考。
Inner Mongolia is the main region of potato production,but the yield per unit area is lower than the average level in China.Water resource shortage and the absence of the water management technology for potato production system are of the major reasons.In this paper,the situation and problems of local potato water usage are analyzed,and the guidelines for increasing water use efficiency are proposed,including integrating the technologies of＂Accumulation,storage,maintenance and usage＂for rain-fed potato and＂Right mode,Right timing and Right rate（3Rtechnology）＂for irrigated potato production.It will provide the foundation for high yield and high water use efficiency of local potato production.
