摘　　要：为验证缓释尿素的肥料利用率和应用效果,采用对比试验的方法,以普通尿素作对照,研究5种缓释尿素对玉米和水稻产量的影响。试验结果表明,在等养分含量处理条件下,缓释尿素对玉米和水稻两种作物均具有增产作用,但差异不显著;5种缓释尿素都能不能程度地提高玉米的肥料利用率,且效果优于水稻。The effect of five kinds of controlled release urea on maize and rice yield was studied adopting contrast test with common urea as the control. The experimental results show that slow release urea can increase the harvest of maize and rice, but the difference was not significant and the 5 slow release ureas can increase the corn fertilizer utilization rate, and the effect is better than that of rice.
