Wheat was the dominating crop in aspects of both the growth and mn nutrients competition either in wheat - rape or in wheat - chickpea intercropping system , but the growths of rape and chickpea were suppressed by wheat . root barriers did not affect the total shoot dry weight in wheat - oat system , but the total mn uptake was lower in no barrier treatment ( mixed cropping ) than in solid barrier treatment ( mono cropping ) 在本试验条件下，小麦与油菜或鹰嘴豆混作能显著改善小麦的生长及锰营养，其地上部干重及吸锰量均以根系不分隔处理显著高于根系完全分隔处理；油菜和鹰嘴豆的生长受小麦抑制，均表现为不分隔处理的地上部干重及吸锰量显著低于完全分隔。
