【摘要】 采用溶液培养法研究了不同浓度镉离子条件下高丹草根系对钾离子吸收的变化。实验结果表明:高丹草根系在镉离子浓度为150μmol/L、200μmol/L浓度下对钾离子吸收能力更强。也就是微量镉离子对高丹草根系吸收钾离子有一定的促进作用。更多还原

【Abstract】 Adopting solvent cultivation method to study the influence that Sorghum bicolor×S.Sudanense(F1) root system absorbs K.ion under different concentrations of Cadmium.The experimental results indicate: root system absorbs K.ion better when Cadmium density is under 150μmol/L 200μmol/L.That is to say,low concentrations of Cadmium promote the absorption of K.ion更多还原
