| 摘 要： | 在2009-2011年连续3年4季田间试验条件下，研究树脂包膜尿素和普通尿素不同掺混比例对水稻-油菜轮作系统中的作物产量和氮肥利用率的影响。结果表明，与当地农民习惯施用普通尿素处理(N 180 kg·hm-2)相比，等氮量下控释氮肥与普通尿素用量为7:3的控释氮肥处理水稻和油菜增产效果最好， 平均产量分别为9 934和2 117 kg·hm-2，增产7.00%和17.03%；控释氮肥处理水稻和油菜的氮肥吸收利用率平均分别增加9.76～25.84和3.85～10.67个百分点，氮肥农学利用率和偏生产力也有显著增加。

| Abstract: | The effects of different mixture ratios of polyester resin-coated urea (PCU) to prilled urea (PU) on yield and nitrogen (N) efficiency under rice-rape rotation was investigated via field experiments during 2009 - 2011. The results showed that compared to the treatments of PU at the N application rate of 180 kg·hm-2 as conventional management practices for local famers, the average yields of rice and rape were 9 934 and 2 117 kg·hm-2 under the treatment of PCU mixed with PU (PCU: PU, 126: 54 kg·hm-2), which significantly increased by 7.00% and 17.03%, respectively. The application of PCU significantly increased N uptake efficiency for rice and rape by 9.76%-25.84% and 3.85%-10.67%, respectively, as compared to the conventional practices. These results indicated the N agronomy efficiency and N partial factor productivity were significantly improved with the mixed application of PCU. |
