摘    要:在三种不同的栽培技术中,地膜覆盖平均WUE为1.69kg/mm较平作平均WUE1.26kg/mm提高34.13%水分利用率,垄作平均WUE为1.47kg/mm较平作提高16.67%水分利用率,脱毒马铃薯的平均WUE为1.60kg/mm,未脱毒马铃薯的平均WUE为1.34kg/mm,水分利用率提高19.35%。平作种植方式马铃薯现蕾至成熟期需水量占整个生育期到90%左右;垄作种植方式76.86% ̄83.3%;地膜覆盖种植方式73.08% ̄77.08%,垄作与地膜覆盖后马铃薯水分的利用趋于合理。进行地膜覆盖和垄作后能使植株健壮,单窝薯重,大中薯商品薯率高,从而提高马铃薯的产量。

关 键 词:马铃薯  栽培技术  水分利用率

Abstract:The middle cultivating technology different in three kinds,average WUE of film mulching does average WUE1.26kg/mm for 1.69kg/mm are on the same level comparatively improve 34.13% the utilization ratio of water,average WUE assumes ridge culture for 1.47kg/mm are on the same level comparatively improving 16.67% the utilization ratio of water,Average WUE taking off the poisonous potato is 1.60kg/mm,average WUE not having taken off the poisonous potato is that 1.34kg/mm,the utilization ratio of water improve 19.35%.The tie does the flower bud now cultivating the way potato arrive at 90% or so till the maturation period water requirement takes up the entire child-bearing period;Way ridge culture is cultivated 76.86%~83.3%;Way film mulching is cultivated 73.08%~77.08%,potato moisture content making use of tends to reasonableness behind ridge culture and film mulching.And being able to after ridge culture makes the film mulching being in progress healthy and strong planting,the nest potato duplicates each other only,the big middle commodity potatos leads height,raises potato''s output thereby.
Keywords:Potato  Cultivating technology  The utilization ratio of water
