摘要： 田间测定结果表明，无芒雀麦与沙打旺带状间作种植可以显著提高无芒雀麦的生产力，使其绿期延长，并促进了沙打旺的生长。在水分利用方面，无芒雀麦与沙打旺带状间作能够较好地保蓄浅层土壤水分和利用土壤深层水分，有利于土壤水分的利用和循环。

Abstract: The seasonal aboveground biomass and soil water of bromegrass (Bromus inermis) under sole cropped and strip intercropped with Astragalus adsurgens were comparatively studied. The results showed that strip intercropping could significantly improve bromegrass productivity and postponed its green growth periods, and also could maintain upper layer soil moisture, promoted the use of lower layer soil moisture, which was favorable to soil water use and cycle.
