摘要
以位于浙江省绍兴市某地的酸性镉汞复合污染稻田为对象,以不施用土壤调理剂作为对照(CK),通过随机区组试验比较了3种土壤调理剂对水稻安全生产和稻米铁、锌含量的影响。结果表明:与CK相比,所施用的3种土壤调理剂均能显著(P<0.05)降低土壤有效态Cd和Hg的含量,并将糙米中的Cd、Hg含量降至国家标准限量范围以下,满足水稻安全生产的要求。其中,自主研发的2号土壤调理剂还可显著提高糙米中的Fe、Zn含量,既可保障镉汞复合污染农田的水稻安全生产,又能增强稻米品质,是试验条件下的最佳选择。
In this study,a randomized block experiment was performed in a cadmium(Cd)-mercury(Hg)compound polluted paddy field in Shaoxing City,Zhejiang Province,China.The treatment without application of soil amendments was selected as the control(CK),and the effects of different soil amendments on the safe production and iron(Fe),zinc(Zn)contents of rice were compared.It was shown that all the three soil amendments could significantly(P<0.05)decrease the contents of soil available Cd and Hg,and decrease the content of Cd and Hg in brown rice below the limitation of the national standard,thus guarantee the safe production of rice.Among the tested soil amendments,the self-developed soil amendments No.2 could also significantly(P<0.05)increase Fe,Zn content in brown rice,which not only safeguards the rice production in the Cd-Hg compound polluted soil,but also enhances the nutritional quality of rice,and is the best choice under the experiment conditions.
