| 摘 要： | 目的]研究不同土壤改良剂对菜地系统中重金属的调控效果,为污染菜地的治理提供依据。方法]以青菜和萝卜为材料,以有机肥、栏肥、腐殖酸和石灰作为土壤改良剂,采用大棚小区试验研究不同土壤改良剂对菜地系统重金属的改良作用。结果]4种土壤改良剂对镉和铅在土壤-作物中的迁移均有一定的抑制作用,在土壤-青菜系统中对镉的改良效果为:腐殖酸>石灰>有机肥>栏肥;在土壤-萝卜系统中镉的改良效果为:石灰>栏肥>腐殖酸>有机肥;在土壤-青菜系统和土壤-萝卜系统中,铅的改良效果均为:有机肥>腐殖酸>石灰>栏肥。结论]试验所选的4种土壤改良剂中,腐殖酸和石灰对镉和铅在土壤-作物系统中的迁移具有较好的抑制效果。

| Abstract: | Objective] The study aimed to research the regulatory effect of different soil amendments on heavy metals in vegetable field system and provide the basis for the management of the polluted vegetable field.Method] With pakchoi and turnip as materials and the organic fertilizer,manure,humic acid and lime as soil amendments,the greenhouse plot test was taken to study the improving effect of different soil amendments on heavy metals in vegetable field system.Result] 4 soil amendments all had certain inhibition on the migration of Cd and Pb in the soil-crop system In soil-pakchoi system,the improving effect on Cd was humic acid>lime>organic fertilizer> manure;in soil-turnip system,the improving effect on Cd was lime> manure> humic acid>organic fertilizer,in soil-pakchoi system and soil-turnip system,the improving effect on Pb were organic fertilizer> humic acid>lime> manure.Conclusion] Among the 4 soil amendments selected in the test,humic acid and lime had better inhibition effect on the migration of Cd and Pb in the soil-crop system. |
