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