2、产量最高,130cm+70cm宽窄行、160cm+40cm宽窄行分别减产9.25%和22.27%,差异显著;间作莴苣、黑塌菜和豌豆后,160cm+40cm宽窄行的蚕豆鲜荚分别是增产9.72%、增产14.91%和减产16.98%;130cm+70cm宽窄行的蚕豆鲜荚分别减产6.27%、增产5.86%和减产18.41%;100cm等行种植的蚕豆鲜荚分别减产10.86%、增产3.23%和减产24.07%;3种行距配置间作的3种蔬菜产量,均以160cm+40cm宽窄行最高,130cm+70cm宽窄行次之,100cm等行种植最低。由此得出,行距配置对大棚鲜食蚕豆
3、产量有着显著影响,蚕豆间作蔬菜时其产量表现与行距配置、蔬菜种类密切相关。关键词:鲜食蚕豆;大棚覆盖;间作蔬菜;行距配置;产量中图分类号:S316文献标志码:A论文编号:2013—0096StudyonYieldEfectofFresh-eatingBeanIntercroppedwithVegetableinDiferentWaysinGreenhouseLiuJian,WeiYafeng,YangMeiying,LiBo,WangBo(InstituteofAgriculturalScienceResearchintheYangtzeRiverinJ
