| 摘 要： | 以菠菜、油麦菜、油菜、韭菜、白菜、白萝卜、马铃薯、胡萝卜、甘蓝为试材,采用田间试验的方法,研究了施用有机肥和喷施叶面肥对9种蔬菜富集重金属铅的影响。结果表明:在试验设计范围内,2种施肥方式均能降低蔬菜中的铅含量,但是不同蔬菜作用效果不同,其中以甘蓝降低最为明显,分别为85.38%和62.34%。由于铅在植物体内迁移能力较弱,接球(果实)内铅含量低于整株铅含量。并对试验地区生产的部分蔬菜中铅含量进行抽样调查,表明菠菜存在铅污染风险。该试验结果也说明了菠菜对铅的富集能力大于其它蔬菜。

| Abstract: | The nine vegetables(included spinach,lettuce,rape,leek,Chinese cabbage,white rurnip,potato,carrot and cabbage)were selected as the research matierials in this study.Effects of different fertilizing modes included organic fertilizer and foliar-fertilizer on the content of lead of nine vegetables were studied through field experiment The results showed that two different fertilizing modes could decrease the heavy metal pb absorption capacity of nine vegetables,but the decreased degree was different of nine vegetables.The decreased degree of cabbage was obvious and they were 85.38%and 62.34%.The lead content of fruit was lower than the whole vegetables,for the power of plant migration to lead was weak.The content of lead of vegetables in the same city was investigated and showed the spinach was a risk of lead pollution.This experiment results showed that the enriched capacity of spinach to lead was more than other vegetables. |
