采用田间小区试验方法,选用福建省大面积推广应用的7个水稻品种为试材,在外施PbCl_2不同处理条件下,研究了不同基因型的水稻稻米对蕈金属元素Pb的吸收累积差异.结果表明,在不同浓度的Pb处理下,水稻糙米中Pb含量在品种间存在显著差异,而且不同水稻品种的籽粒对土壤中重金属Ph的敏感性不同,以此可找出适合污染地区种植的品种.

With seven rice cultivars as materials which were popularized and applied in a large area in Fujian, the differences of absorption and accumulation of heavy metal lead(Pb) in grains of different rice genotypes were studied by different application of exogenous PbCl_2. The results showed that the content of Pb in grains showed significant differences between the rice cultivars at different Pb concentration treatment. Furthermore, the sensitivity of grains of different rice varieties to heavy metal Pb in soils was different. Then, the rice varieties which were suitable for cultivation in polluted areas could be identified.
