摘　　要：利用给鸡饲喂50mg·kg-1和80mg·kg-1洛克沙生得到的鸡粪进行盆栽试验,研究两种含砷鸡粪对青菜和番茄中砷含量、砷富集因子的影响。结果表明,含砷鸡粪施肥后青菜和番茄植株中砷含量均明显提高;青菜砷含量、砷富集因子高于番茄植株,青菜有明显的砷富集作用;番茄植株中砷含量与其生物量呈负相关、未表现出对砷的富集作用。不同种属蔬菜在含砷鸡粪施肥后对砷有不同的摄入,青菜对砷有明显的富集现象,提示青菜在含砷鸡粪施肥后砷水平有较大影响,存在着砷超标风险。The pot cultivation experiments were conducted to investigate the As content and As accumulation of chinese pakchoi cabbage and tomato shoots in soils amended with As-bearing chicken manures which were obtained from feeding 50 mg kg-1 and 80 mg kg-1 roxarsone to chicken respectively. A one-way analysis of variance（ANOVA） was analyzed the data of As content, biomass, As accumulation factor and chicken manure tested. Results showed As content of two vegetables was significantly higher than the control. The As content and As accumulation factor of pakchoi cabbage were significantly higher than that of tomato shoots, which appeared clear As accumulation trend in pakchoi cabbage. The As content of tomato shoots was negatively correlated with its biomass and the As accumulation phenomena was not appeared. A conclusion was that As uptake capability was depended on its vegetable species and pakchoi cabbage appeared clear As accumulation trend in As contaminated soils. It is implied that heavy application of As containing manures should be avoided in produce of vegetable species with high accumulated potential like as pakchoi cabbage for As safety of foods.
