摘  要:
通过土培试验、水培试验和佐证试验,探讨了硫肥中SO42-离子对小白菜Cr(VI)污染毒性的调控作用。结果表明:适当提高SO42-离子浓度能促进铬的有机态转化并降低有效态铬含量,从而抑制土壤铬的活性,有效抑制小白菜对Cr吸收,但过高SO42-离子浓度有一定盐胁迫毒害效应,会影响其对降低小白菜Cr生物毒性的作用。

摘  要:
By pot experiment,hydroponics experiment and test experiment.the effects of base anions(SO42-)in S'Fertilization on Cr(VI) toxicity of pakchoi cabbage(Brassica campestris L.ssp.chinensis(L.))and its regulation and control mechanism were studied.The results showed that: suitable will promit,with the increasing of sulfate anions(SO42-)concentration in nutrient solution,the orginic transferation of Cr and decrease the effective Cr contents were and therefore,the Cr activity in soil was inhibited and the Cr uptake by pakchoi cabbage was decreased obviously.However,high sulfate anions concentration in water culture resulted in salt toxicity somewhat to pakchoi cabbage and therefore reduced its resistance of Cr toxicity.
