| 摘 要： | 通过大田试验,研究硫磺加树脂包膜控释尿素不同掺混比例在玉米上的施用效果。结果表明:玉米控释尿素最佳掺混比例为PCU50%+PU50%。PCU50%+PU50%处理的玉米产量最高,比其它施氮处理增产391 kg/hm2(3.5%)～1 535 kg/hm2(15.3%),达到显著水平,氮素利用率最高,达44.5%。

| Abstract: | The field experiment was carried out to study effect of applying different mixing ratio of the sulfur plus Resin-coated urea on maize.The results indicated that the optimum ratio was 50% PCU + 50% PU.The yield with 50%PCU + 50%PU treatment was the highest compared with the other treatments,which increased by 391kg/ha(3.5%) to 1535kg/ha(15.3%),and whose utilization rate for N was the highest(44.5%). |
