摘    要:通过田间小区试验,研究了玉米、青花、白菜和油毛菜间作及套作马铃薯、豌豆和西葫芦对重金属Cd、Pb、Cu累积含量的影响。结果表明,玉米与油毛菜间作与单作相比较,玉米中Cd含量显著下降了72.9%,油毛菜中Cu含量显著下降了49.8%,套作西葫芦时Pb含量显著下降了56.8%;间套作条件下,显著降低了重金属Cd、Pb、Cu在玉米和蔬菜可食部分的累积含量,与单作相比平均下降了30%、37.9%和28.6%。玉米和不同蔬菜间套模式是抑制作物可食部分吸收累积重金属Pb、Cu、Cd含量的有效措施。

关 键 词:玉米  蔬菜  间套模式  Pb  Cu  Cd  累积

Abstract:Field trials were carried out to investigate the effects of accumulation of Pb,Cu and Cd in plants under maize and vegetables intercropping system, such as cauliflower, cabbage, lettuce, pea, potato and pumpkin. The results showed that contents of Cd in maize, Cu in lettuce and Pb in pumpkin decreased by 72.9%, 49.8% and 56.8% in intercroping system compared with monoculture system. The contents of Cd, Pb and Cu in the edible part of maize and vegetables decreased 30%, 37.9% and 28.6% in intercropping syste...
Keywords:maize  vegetable  intercropping system  Pb  Cu  Cd  accumulation
