DA-6强化龙葵修复高镉污染土壤的作用
Effect of DA-6 on Enhanced Remediation Efficiency of Solanum nigrum L.in Serious Cadmium Polluted Soil
摘要
Abstract
[ Objective ] The purpose of this experiment was to study the effect of different concentrations of diethyl aminoethyl hexanoate (DA-6 ) on the S. Nigrum L. Biomass and extraction from serious cadmium polluted soil, and discuss the best suitable one which could increase the remediation efficiency. [Method] A pot culture experiment was designed by different concentrations of DA-6 with soaking seed and foliage spraying. [Result] Results showed that at mature stage, S, 10,20 and 40 mg-L1 DA-6 could increase the shoot dry weight by 8.69%-27.54% (P<0.05), cadmium concentration by 2.62%-6.75% and total cadmium extraction by 10.12%-36.31 % (P < 0.05). MDA got decreased at seedling and mature stages, while SPAD meter value increased; POD activity increased at seedling stage, but decreased at mature stage. [Conclusion] All treatments designed enhanced remediation efficiency, while 20 mg-L'1 DA-6 was the best one.关键词
