摘　　要：通过大麦/蚕豆间作盆栽试验,研究了间作中大麦和蚕豆各生育期土壤含水量的差异以及间作大麦与单作大麦土壤含水量的差异。结果表明,大麦苗期后期至抽穗期,蚕豆土壤含水量下降比大麦快。而在苗期前期和成熟期,大麦土壤含水量下降比蚕豆快。在大麦整个生育期中,间作大麦土壤含水量下降都比单作大麦快,尤其是在拔节至孕穗期下降最快。The pot experiment of barley and broad bean intercropping was conducted to investigate the difference of soil moisture content between barley and broad bean at different growth stages in intercropping system, the difference of soil moisture content between barley intercropping and barley monocropping systems. The results showed that the soil moisture content of broad bean decreased faster than that of barley from the late stage of seedling to heading stage, but the soil moisture content of barley decreased faster than that of broad bean at the early stage of seedling and ripening stage. The soil moisture content of barley intercropping system decreased faster than that of barley monocropping system at all growth stages, especially from jointing stage to booting stage, the soil moisture content of barley intercropping decreased the fastest.
