摘  要：
通过水培试验,对畜牧业中广泛使用的典型兽药强力霉素,开展了4种叶菜(绿罗莎、苦苣、绿箭和绿直立)的吸附富集特征及去除规律研究,评价抗生素环境污染的植物修复能力。结果表明:强力霉素在有蔬菜种植的培养液中降解速度明显快于无蔬菜种植的培养液,空白对照组中去除率37. 8%,而在叶菜处理组中去除率超过95%,在空白对照培养液以及绿罗莎、苦苣、绿箭和绿直立的培养液中强力霉素去除半衰期分别为22. 1 d、1. 4 d、1. 5 d、2. 3 d和2. 8 d,与空白对照相比差异极显著(P<0. 01);在吸收富集能力上,绿罗莎和苦苣茎叶部分对强力霉素具有较强的累积作用,富集系数分别为7. 20和4. 95,而绿箭和绿直立的富集系数分别为0. 76和0. 49,累积作用相对较弱。说明富集能力较强的蔬菜作物可作为降低抗生素环境污染的备选植物。

摘  要：
To evaluate the phytoremediation of the antibiotic environmental pollution,hydroponic experiment was carried out to study adsorption enrichment characteristics and removal law of veterinary drug doxycycline in four kinds of leaf vegetables( Lvluosha,endive,Lvjian,Lvzhili). The results showed that the degradation rate of doxycycline in the culture medium with vegetables was significantly faster than that in the medium without vegetables. The removal rate was 37. 8% in the control group,while the removal rate in the leaf vegetable experimental group was more than 95. 0%. Compared with the control group,the difference was very significant( P<0. 01) in the vegetable experimental group and the removal half-lives were 22. 1 d,1. 4 d,1. 5 d,2. 3 d and 2. 8 d,respectively. In the capacity of absorption and enrichment,the stem and leaf of Lvluosha( Lactuca sativa) and endive( Sonchus oleraceus) had stronger accumulation of doxycycline,and bioconcentration factor( BCF) values were 7. 20 and 4. 95,respectively. The capacity of accumulation was relatively weaker in Lvjian( Lactuca sativa) and Lvzhili( Lactuca sativa),and BCF values were 0. 76 and 0. 49, respectively. The research results indicated that the vegetable with strong enrichment ability could be used as an alternative plant to reduce the environmental pollution of antibiotics.
