摘　　要：比较了膜下滴灌模式、膜下沟灌模式、露地直播沟灌模式3种不同栽培模式下的灌溉量、块根产量、产糖量的关系。研究表明,膜下滴灌模式,每667m2灌溉量在360 m3时为最适灌溉量,块根产量、产糖量达到最高;膜下沟灌模式,每667m2灌溉量在600 m3时为最适灌溉量,块根产量、产糖量达到最高;露地直播沟灌模式,每667m2灌溉量在700 m3时为最适灌溉量,块根产量、产糖量达到最高。膜下滴灌是种植甜菜最佳的节水灌溉方式,与膜下沟灌模式相比每667m2节水240 m3;与露地直播沟灌模式相比,每667m2节水340 m3;是我国干旱、半干旱甜菜种植区需要采用的灌溉模式。Three different cultivation modes of the film with membrane under drip irrigation, furrow irrigation under membrane, bare diteh irrigation mode were taken to test the relationship between irrigation amount, root yield, and sugar yield. Preliminary research showed that in membrane under drip irrigation mode, the optimal irrigation amount was 360 m^3/667 m^2, root yield and sugar yield reached the highest; in furrow irrigation under membrane model, the optimal irrigation amount was 600 m^3/667 m^2, root yield and sugar yield reached the highest; in bare diteh irrigation mode, the optimal irrigation quantity was 700 m^3/667 m^2, yield and sugar yield were upto the highest. Therefore, membrane under drip irrigation was as the best water-saving irrigation for planting sugarbeet, water-saving was in 240 m^3/667 mS and 340 m^3/667 m^2 respeetively, in comparison with the furrow irrigation under membrane model and the bare ditch irrigation mode; the irrigation mode could be adopted for China＇s arid and semi-arid of beet area.
