摘　　要：以水稻品种特优582为试材,研究常规拖拉机耕作和粉垄耕作2种耕作方式对水稻富硒(Se)营养化及重金属含量的影响。结果表明,粉垄耕作有利于提高水稻产量和经济效益,分别提高了4.19%和6.36%;粉垄稻谷硒(Se)、锌(Zn)元素含量分别增加了78.14%和15.99%;砷(As)、铬(Cr)含量比对照下降;铅(Pb)、总汞(Hg)、镉(Cd)含量比对照增加,其含量在国家标准限量范围内。因此,粉垄耕作稻田对稻谷产生的营养性影响利大于弊。The rice variety of Teyou 582 was chosen as the experimental material to research the effects of two tillage methods （conventional and smash-ridging tillage）on selenium nutrition and the heavy metal contents of rice.The resuhs showed that smash-ridging tillage was beneficial to improve the yield and economic benefit of rice ,which increased by 4.19% and 6.36% respectively. The contents of Se and Zn increased by 78.14% and 15.99% respectively.The contents of As and Cr decreased, and the contents of Pb, total Hg and C d increased compared with the control, but were within the limits of national standards. Therefore, the nutritional effects of smash-ridging tillage on rice production has more advantages than disadvantages.
