| 摘 要： | 中国南方土壤镉污染现象较为严重,对中国农业发展及农产品安全带来很大影响。植物修复是解决镉污染农田一个发展前景较好的方法,但缺少合适的修复植物。在本研究中,以长江中下游地区大面积种植的经济作物——甘蓝型油菜为对象,利用盆栽的方式,研究0、5、15、25 mg/kg 4个浓度梯度下,镉超标对油菜生长、菜油品质的影响。结果发现,镉超标对油菜生长有一定影响,但菜油中镉含量远低于国际标准要求,表明产自镉污染土壤的菜籽油并不影响其食用价值。且利用油菜作为修复植物,还可增加当地农民收益和中国菜油供应,缓解日益严重的食用油供给不足现状,因此油菜是一种较为理想的镉污染土壤修复植物。

| Abstract: | Soil cadmium pollution is serious in southern China, and has a great deal of adverse effects on agriculture development and safety of agricultural products. Phytoremediation is a promising way to restore cadmium contaminated farmland, but suitable phytoremediation plants are insufficient. In this study, an economic crop of Brassica napus, which is widely planted in the middle and lower reaches the Yangtze River, is taken as raw material to study the effects of excessive cadmium content on Brassica napus growth and the quality of rapeseed oil. Four different cadmium concentrations of 0, 5, 15 and 25 mg/kg are adopted in pot cultivation. The results show that excessive cadmium content could have adverse effects on the growth of Brassica napus, but the cadmium content in rapeseed oil is far lower than that in the international standard, indicating that the rapeseed oil produced on cadmium pollution soil would not affect its consumption value. At the same time, Brassica napus used as remediation plant could increase the income of local farmers and the supply of vegetable oil in China, to alleviate the increasing shortage of edible oil supply. Therefore, Brassica napus is an ideal remediation plant for cadmium contaminated soil. |
