水稻田重金屬污染的治理方法

張秀, 黃興奇, 賀斌, 殷富有, 張敦宇, 程在全中國農學通報, 2013, 29(21): 1-5 DOI: 10.3969/j.issn.1000-6850.2013.21.001; 追溯原文......本站官方QQ群：62473826水稻田; 重金屬; 低吸收水稻; 土壤改良劑; 超富集植物; 轉基因植物

有必要了解重金屬污染的現(xiàn)狀、危害及其治理策略。根據水稻田的重金屬污染情況，選用符合能在水稻田中減輕重金屬污染的實施方法：控制重金屬污染源，篩選重金屬低吸收的水稻品種，利用土壤改良劑，種植超富集植物，種植轉基因植物。實施方案有利于提高水稻的產量及其品質，間接有利于人類身體健康。目前選育出來的低積累水稻品種還比較少，需要選育出更多品種；超富集植物的選擇，要從能修復單一重金屬污染向能修復復合重金屬污染轉變，才能適應污染地的復雜情況；轉基因植物可利用空間還有待開發(fā)；歸根結底要重視重金屬污染，控制污水灌溉。

Management Methods of Heavy Metal Pollution in the Rice Fields

It is necessary to realize the current situation, harm, and management strategies of heavy metal pollution. On the basis of the situation of heavy metal pollution in the rice fields, the best methods which were match with rice fields can be chosen, including controlling heavy metal pollution sources, screening rice varieties of low absorption of heavy metal, using soil amendment, planting hyper-accumulator and growing transgenic plants. These methods were beneficial to improve yield and quality of rice, thus beneficial to human health. Now there were few rice varieties of low absorption of heavy metal, so greater efforts were needed in the future. Also, only if the select of hyper-accumulator change from repair single heavy metal pollution to compound, it could adapt to the complication of pollution places. What was more, there was a great space to develop transgenic plants. In a word, much attention should be paid to heavy metal pollution and control sewage water irrigation.
