摘　　要：[目的]为玉米氮素高效利用提供技术支撑。[方法]采用夏玉米盆栽试验,共设7组处理,研究控释尿素和普通尿素不同配比对玉米各生育期与收获期的生物量及产量的影响。[结果]玉米不同生育期的生物量随控释尿素比例的增大而增加,且使用一定比例控释尿素处理的生物量大于普通尿素处理,以处理⑥最大;在玉米收获期,处理⑥的产量最大,与其他处理间达差异极显著水平,处理⑤次之,产量高于处理②。[结论]综合考虑,确定处理⑤(55%普通尿素+45%控释尿素)为最佳配比。[ Objective ] The study aimed to provide technical support on high nitrogen use. [ Method] Set up 7 treatments, the effect of controlled-release urea combined with common urea on biomass and yield of summer corn were studied by the method of corn pot experiment. [ Result ] The biomass of different growth period were increased with increasing of proportion of controlled-release urea, and the treatment of controlled-release urea were higher than common urea, treatment ⑥ reached the maximum; In the harvest period, treatment ⑥ had the most yield, contrast with the other treatments, its difference was extremely significant, secondly for treatment ⑤, and its yei]d was higher than treatment ②. [ Conclusion ] Treatment ⑤ was the best proportion by comprehensive consideration.
