为研究湖南湘江流域稻田镉(Cd)污染治理方法,筛选稻田替代种植作物,于长沙县和湘阴市受污染稻田改种花生,选用5个大果品种,设置2种(露地、覆膜)栽培方式,研究品种与栽培方式组合下对稻田Cd吸收、富集及转运的影响。结果表明:稻田花生营养器官(根、茎、叶)Cd含量较高,生殖器官(果壳、籽仁)Cd含量较低,且品种间有明显差异。5个花生品种的组织器官中Cd含量最高的是茎(5.413~8.859mg·kg~(-1)),果壳和籽仁最少(0.523~ 1.326mg·kg~(-1)),但是籽仁Cd含量超出NY/T 1067-2006标准的规定值,食用安全存在风险。覆膜栽培尽管降低了花生茎、叶、果针、果壳及籽仁等的Cd含量,但提高了植株干物质重和Cd总积累...

To reduce cadmium (Cd) pollution in paddy fields in Xiangjiang River Basin in Hunan Province,peanut was planted as expected replacing crop in Cd polluted paddy fields in Changsha and Xiangyin City.5 largeseed peanut varieties were selected and 2 different cultivation methods (open field and plastic film cultivation) were tested.By investigating peanut Cd uptake,enrichment and transport,the Cd concentration and translocation in paddy fields were studied.Results showed that Cd contents in vegetative peanut organs (roots,stems and leaves) were hig...
