| 摘 要： | 研究了外源有机酸(草酸、柠檬酸)和EDTA对铅胁迫蒜苗的缓解效应.结果表明:在铅污染土壤上施用外源柠檬酸+草酸、EDTA、柠檬酸+草酸+1/2 EDTA、柠檬酸+草酸+1/3EDTA可增强蒜苗抗性,提高产量,降低铅含量,改善蒜苗品质.综合蒜苗各品质指标及铅含量,以使用柠檬酸+草酸+1/3EDTA效果最好,该处理明显降低了蒜苗铅含量,又缓解了EDTA对蒜苗品质的负面效应,对铅污染土壤上蒜苗安全生产可起到积极效果.

| Abstract: | The results from studying the effect of exogenous organic acids(oxalic acid,citric acid) and EDTA on quality of garlic sprouts planted in soils with different Pb contents showed that the application of exogenous citric acid + oxalic acid,EDTA,exogenous citric acid+ oxalic acid + 1/2 EDTA and exogenous citric acid+ oxalic acid + 1/3 EDTA all can raise its resistance and yield,reduce its Pb content and improve its quality.The exogenous citric acid+ oxalic acid + 1/3 EDTA application pattern has the best effec... |
