有必要了解重金属污染的现状、危害及其治理策略。根据水稻田的重金属污染情况，选用符合能在水稻田中减轻重金属污染的实施方法：控制重金属污染源，筛选重金属低吸收的水稻品种，利用土壤改良剂，种植超富集植物，种植转基因植物。实施方案有利于提高水稻的产量及其品质，间接有利于人类身体健康。目前选育出来的低积累水稻品种还比较少，需要选育出更多品种；超富集植物的选择，要从能修复单一重金属污染向能修复复合重金属污染转变，才能适应污染地的复杂情况；转基因植物可利用空间还有待开发；归根结底要重视重金属污染，控制污水灌溉。

Management Methods of Heavy Metal Pollution in the Rice Fields

Zhang Xiu, Huang Xingqi, He Bin, Yin Fuyou, Zhang Dunyu, Cheng ZaiquanChinese Agricultural Science Bulletin, 2013, 29(21): 1-5

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.
