柠檬酸对白茅和藨草吸收重金属的影响

The Effects of Citric Acid on Imperata Cylindrica's and Scirpus Triqueter's Absorbing Heavy Mental

为探讨柠檬酸对植物积累重金属的影响,选择在污染区采集的白茅和藨草种子,采用在不同浓度梯度的柠檬酸调控下温室盆栽法白草(Imperata cylindrica L.)和藨草(Scirpus triqueter L.)三个月后测定对Cd,Zn,Pb积累变化.结果表明:柠檬酸增加了对白茅和草对Cd,Zn,Pb积累.

The paper is to explore the effects of ctric acid on plants＇ amassing heavy mental. The research is conducted by sampling Imperata cylindrica and scrirpus tripueter seeds planted in the polluted area and the seeds planted in the greenhouse with the regulation of ctric acid and the absorption of Cd, Zn, and Pb was to evaluated in three months. The result indicated that th.e ctric acid increased Imperata Cylindrica＇ s and Scirpus Triqueter＇ s absorbing of Cd, Zn, and Pb.
