摘　　要：通过小麦/蚕豆间作和大麦/蚕豆间作盆栽试验,研究了间作与单作相比在耗水量及水分利用率方面的差异。研究结果表明,小麦/蚕豆间作全生育期耗水量比小麦单作和蚕豆单作低,但差异未达到显著水平;小麦/蚕豆间作在蚕豆分枝期耗水量比蚕豆单作低,且差异达到显著水平。大麦/蚕豆间作全生育期耗水量比大麦单作高,但差异未达到显著水平;大麦/蚕豆间作在大麦分蘖期耗水量比大麦单作高,且存在显著差异。大麦/蚕豆间作各生育期及全生育期耗水量与蚕豆单作相比不存在显著差异。间作小麦、间作大麦的WUE(水分利用率)比单作小麦、单作大麦高,但间作蚕豆的WUE比单作蚕豆低。The pot experiment of wheat/broad bean intercropping and barley/broad bean intercropping were conducted to investigate the difference between intercropping and monocropping in water consumption and water use efficiency （WUE）. The results showed that water consumption of all growth stage of wheat/broad bean intercropping were lower than wheat monocropping and broad bean monocropping. There were significant difference between wheat/broad bean intercropping and broad bean monocropping in broad bean branching stage. The water consumption of all growth stage of barley/broad bean intercropping was higher than barley monocropping. There was significant difference between barley/broad bean intercropping and barley monocropping in barley tillering stage. There was no significant difference between barley/ broad bean intercropping and broad bean monocropping in barley individual growth stage and all growth stage. WUE of wheat intercropping and barley intercropping was higher than that of wheat monocropping and barley monocropping, but WUE of broad bean intercropping was lower than that of monocropping.
