| 摘 要： | 在砂薄地上研究了夏玉米施用缓／控释氮肥ZP（包膜氮肥）的效果，结果表明，缓／控释氮肥ZP1次性施用、或以质量比1：1比例配合尿素施用，其增产效应和氮肥利用率与尿素分2次施用无显著差异，与尿素1次施用相比，氮肥肥效和肥料利用率均显著提高。

| Abstract: | Plot test was used to study the effect of ZP controlled release N fertilizer on summer maize in sandy soil. The result showed that: in tested condition,there were no significant differencs in both N fertilizer utilization rate and yield-increasing effect between the treatment of applying 100% slow/controlled release fertilizer ZP once, or 50% urea plus 50% slow/controlled release fertilizer ZP once and the treatment of applying 100% urea twice, moreover, compared with the treatment of applying 100% urea once,all the three treatments mentioned above had significant higher yield-incneasing effect and N fertilizer utilization rate. |
