摘要： The effects of tolerant plants (Ranunculus sieboldii, Mazus japonicus, Clinopodium confine and Plantago asiatica) straws on nutrient uptake in Cd-accumulator Capsella bursa-pastoris were investigated through pot experiment under Cd-contaminated soil condition. Five treatments were used in the experiment: not mulched with straw (control), mulched with R. sieboldii straw, mulched with M. japonicus straw, mulched with C. confine straw, and mulched with P. asiatica straw. Mulching with four tolerant plant species straws on Cd-contaminated soil surface increased phosphorus (P) and potassium (K) contents in roots and shoots of C. bursa-pastoris compared with control. The P and K contents in plants were ranked as P. asiatica straw > C. confine straw > M. japonicus straw > R. sieboldii straw > control. The soil available P and K contents were increased by tolerant plant straw, which were ranked as: P. asiatica straw > C. confine straw > M. japonicus straw > R. sieboldii straw > control. Mulching with four tolerant plant species straws also enhanced soil sucrase, urease and catalase activities. Therefore, Mulching with tolerant plant straw could used to increase nutrient content and enhance soil enzyme activity in C. bursa-pastoris for the phytoremediation of Cd, and the P. asiatica straw was the best.
