摘要 通过田间试验方法,对比评价控释尿素在夏玉米上的施用效果和方法。根据施用控释尿素对玉米籽粒产量、氮素吸收和利用率的影响,探讨控释尿素在夏玉米上的施用效果。试验结果表明:与普通尿素相比,施用控释尿素后,玉米产量及氮素利用率均明显提高。 Through field experiments the results and methods of comparison and evaluation are given for the application of controlled release urea on summer corn. Based on the effect of controlled release urea applied on the output of corn seed and nitrogen absorption and utilization, the results are investigated of controlled release urea applied on summer corn. The experimental results show that with the application of controlled release urea, both the corn yield and nitrogen availability increase significantly.
