| 摘 要： | 采用盆栽试验,在不同镉(Cd)污染浓度的灰漠土中分别添加蚯蚓和新鲜秸秆,研究了添加蚯蚓和秸秆还田条件下油菜(Brassica rapa L.spp.Chinenesis)-土壤体系中Cd的分布情况.结果发现:(1)添蚯蚓可有效增加土壤中Cd向油菜体内转移;蚯蚓可以在Cd污染的土壤中生存,蚯蚓体内Cd浓度随土壤环境中Cd...

| Abstract: | In pot experiments,earthworms and fresh straw were added into gray desert soil with different concentrations of Cd pollution to study the rape(Brassica rapa L.spp.Chinenesis) Cd accumulation in the soil system under two treatments: earthworm and straw additions.The results showed that:(1) Under different conditions of soil Cd-pollution,the addition of earthworms can effectively promote Cd in the soil to transfer into rape;earthworms can survive in the Cd-contaminated soil,while with the increase of Cd in th... |
