摘　　要：通过根箱试验,研究了交替灌溉对小麦间作蚕豆的产量、根质量、根长的影响,以期探讨将交替灌溉技术集成到间作中的可行性.结果表明:与传统灌溉方式相比,交替灌溉使单作小麦的经济产量、生物产量、根质量、根长分别提高了14.7%、2.9%、6.4%、7.2%,使间作小麦分别提高了21.1%、13.2%、16.1%、16.0%;交替灌溉使单作蚕豆的经济产量、生物产量、根质量、根长分别提高了4.2%、1.8%、2.1%、6.8%,间作蚕豆分别提高了13.3%、5.8%、5.1%、24.1%;在交替灌溉条件下,间作小麦和蚕豆增产幅度高于单作,因此认为将交替灌溉技术应用到间作中有利于促进间作小麦蚕豆的根的生长,提高产量.In this study,a root box experiment was carried out to investigate the influence of alternative irrigation on the yield,root weight and length of wheat and faba bean in mono-cropping and intercropping systems,in order to search evidence for integrating alternative irrigation into intercropping.Results showed that,compared to conventional irrigation treatment correspondingly,the seed yield,biomass,root weight,root length of mono-cropping wheat was increased by 14.7 %,2.9 %,6.4 %,7.2 % respectively,and that of the intercropping wheat was increased by 21.1 %,13.2 %,16.1 %,16.0 % respectively;and the seed yield,biomass,root weight,root length of alternative irrigated mono-cropping and intercropping faba bean was increased by 4.2 %,1.8 %,2.1 %,6.8 % and 13.3 %,5.8 %,5.1 %,24.1 % respectively.Under alternative irrigation,the yield of intercropping wheat and faba bean was higher than that of the mono-cropping ones,this confirmed that integrating alternative irrigation into intercropping system was feasible.
