摘　　要：采用盆栽试验,研究了南京和北京土壤中Pb污染对青菜生长的影响。结果表明:土壤质地对青菜生长有明显的影响;在土壤Pb含量低的处理水平下,对青菜的生长有一定影响;低含量范围内,青菜中Pb含量随土壤Pb处理含量的增加出现先升后降的变化趋势;在100 mg/kg时,青菜的生长受到抑制,植株中Pb的含量高于对照组和200 mg/kg Pb处理。The pot experiment was conducted to study the effect of lead, especially at low levels, in Nanjing and Beijing soils on the growth of Brassica campestris SSP. chinensis Makino. Results show that the texture of soil and lead pollution had effects to a certainty on the growth of Brassica campestris SSP. chinensis Makino. Lead content in plant presented an increase-to-decrease trend with the rising concentration of soil lead. Under the treated concentration of lead at 100 mg/kg, the growth of Brassica campestris SSP. chinensis Makino was inhibited and the content of lead in the plant was higher than control groups.
