摘要

选用吊兰进行室内盆栽，研究在Cd污染土壤中，施用不同剂量磷肥对吊兰生理指标、土壤酶活性等的影响，为合理施用磷肥，提高Cd污染土壤的植物修复效果提供参考依据。结果表明：吊兰在100 mg/kg的Cd污染土壤中能正常生长，施P对吊兰的叶绿素、细胞膜透性、抗氧化酶活性影响显著（p<0.01），表现为低浓度促进，高浓度抑制作用。当施磷量为200 mg/kg时，叶绿素含量、CAT酶活性最大，外渗电导率和MDA含量最低，POD酶活性开始上升，说明施磷能使吊兰的细胞膜受害程度最低，抗氧化作用增强。同时，施P有利于改善Cd污染土壤的酶系统，对过氧化氢酶、脲酶的活性表现为低浓度促进、高浓度抑制，对蔗糖酶的活性表现相反，对磷酸酶的活性表现抑制作用；且200 mg/kg的磷处理时，过氧化氢酶、脲酶的活性最高，蔗糖酶的活性最低。4种土壤酶活性均与P浓度呈高度相关性（p<0.05），相关性为脲酶>过氧化氢酶>蔗糖酶>磷酸酶。

Abstract

The effect of phosphate fertilization on the growth of Chlorophytum comosum and soil enzyme activities in Cd-contaminated soils were investigated. The results showed that C. comosum was able to grow well in Cd-contaminated soils contained 100 mg/kg Cd. The appropriate addition of P fertilization was capable of distinctly improving chlorophyll content

cell membrane permeability and antioxidase activities of C. comosum (p<0.01). The chlorophyll content

cell membrane permeability and antioxidase activities of C. comosum were promoted by low P level fertilization and inhibited by high P level fertilization. Both the chlorophyll content and the CAT activity increased to the maximum at 200 mg/kg of P. Election Conductivity and MDA content dropped to the minimum value at the same time. The POD activity started to rise when the P content were at 200 mg/kg. The results indicated that P addition could reduce the degree of damage to the cell membrane to the lowest level

and significantly enhance antioxidation. Simultaneously

the soil enzyme system in Cd-contaminated soils could also be improved by using phosphate fertilizer. The activities of catalase and urease were enhanced at low P content while they were decreased at high P content. The urease activity showed the opposite trend of the catalase and urease activities. The phosphatase activity was inhibited. Besides

the activities of catalase and urease were elevated to the maximum values while the sucrase activity was decreased to the minimum value at 200 mg/kg of P content. Moreover

the four soil enzyme were highly correlated with P concentration (p<0.05) and the correlation sequence of the four soil enzymes was urease > catalase > sucrose > phosphatase.
