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ZP 1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.
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.
