| 摘 要： | 为了研究控释尿素对吉林春玉米产量和氮肥利用率的影响，通过不同的控释尿素和普通尿素施用量对吉林春玉米进行处理，在吉林省公主岭市陶家屯进行控释尿素施用效果田间小区试验。试验结果表明，全氮用量和75%氮用量情况下，控释尿素与普通尿素相比，对吉林春玉米增产分别为10.8%和8.1%，产量差异显著；且控释尿素与普通尿素混施增产效果高于控释尿素单一施用效果，增产7.3%。全氮用量和75%氮用量条件下，控释尿素氮素利用率分别为50.4%和57.3%，显著高于普通尿素，且75%氮用量氮素利用率高于全氮用量。

| Abstract: | Field plot experiments were conducted to investigate the effects of different application quantities of controlled-releases urea and common urea on spring maize yield and apparent N recovery rates at maize foundation seed farm, Taojia, Jilin Province. The results showed that in comparison with common urea, the controlled release urea at 100% and 75% application rates increased the spring maize yield rate by 10.8% and 8.1%, the difference was significant. Mixed application of controlled release N and common ... |
