| 摘 要： | 通过田间试验,研究控释氮肥与普通尿素不同掺混比例在水稻上的施用效果,试验表明:水稻上控释氮肥最佳掺混比例为PCU50%+PU50%。PCU50%+PU50%处理的水稻产量最高,比其它施氮处理增产250 kg/hm2(3.4%)～503 kg/hm2(7.2%),氮素利用率最高,达44.8%。 |
| 关 键 词： | 水稻 控释氮肥 施用效果 掺混比例 |

| Abstract: | The field experiment was carried out for studying effect of applying release-controlled Nitrogen mixed with different ratio of urea on rice.The results indicated that the optimal blending ratio was 50% PCU + 50% PU.The rice yield increased by 250kg/ha(3.4%)-503kg/ha(7.2%),and whose utilization rate for N was the highest(44.8%). |
| Keywords: | Rice Release-controlled nitrogen Application effect Blending ratio |
