| 摘 要： | 通过小麦-蚕豆间作盆栽试验,研究了小麦-蚕豆间作中小麦和蚕豆、间作与单作在土壤水势变化方面的差异。研究结果表明,在小麦-蚕豆间作中,除小麦苗期外,其它生育期小麦土壤水势下降速度都快于蚕豆,而且在小麦孕穗期下降速度最快,这证明土壤水分除小麦苗期外,其它生育期都由蚕豆向小麦迁移,而且迁移速度在小麦孕穗期最快。间作小麦和单作小麦相比,除小麦苗期前期,间作小麦与蚕豆对土壤水分的竞争较弱,其它生育期间作小麦与蚕豆对土壤水分的竞争都比较激烈。 |

| Abstract: | The pot experiment of wheat/broad bean intercropping was conducted to investigate the difference between wheat and broad bean and intercropping and monocropping in soil water potential.The results showed that soil water potential of wheat decreases faster than that of broad bean in most wheat growth stages,except for wheat seedling stage.The fastest decrease of wheat soil water potential occurred in wheat booting stage.The results imply proved that soil water may move from broad bean to wheat,except for whe... |
