摘　　要： 通过盆栽试验,研究了等氮量下普通尿素(PU,prilled urea)、硫包膜尿素(SCU,sulfur coated urea)和树脂包膜尿素(PCU,polymer coated urea)对污染土壤上水稻Zn吸收特性的影响。结果表明,与施用普通尿素相比,施用树脂包膜尿素和硫包膜尿素处理的水稻籽粒产量分别增加9.83%和1.64%,糙米Zn含量分别降低5.48%和11.2%,但差异不显著。施用树脂包膜尿素和硫包膜尿素促进水稻生长,一定程度上降低糙米中Zn浓度。 A pot experiment was carried out in greenhouse to research the effects of prilled urea(PU), polymer coated urea(PCU) and sulfur coated urea(SCU) on Zn uptake of rice(Oryza sativa L.) under the same nitrogen level in a contaminated soil. Compared to PU, PCU and SCU increased the yield of rice by 9.83% and 1.64% respectively, and decreased Zn concentration in brown rice by 5.48% and 11.2% respectively. Applying PCU and SCU increased the growth of rice, and decreased Zn concentration in brown rice to some extent.
