摘要

通过田间试验研究释放期60d的水基包膜尿素与普通尿素常规施肥用量下不同比例配合追施对夏玉米产量、肥料利用率、氮肥农学利用率、氮肥偏生产力、氮素收获指数、氮素积累量及0-60cm土壤硝铵态氮含量动态分布的影响。结果表明:各控释掺混处理对夏玉米的产量、肥料利用率、氮肥农学利用率、氮肥偏生产力及氮素收获指数较常规施肥都有不同程度的提高

以控氮比50%处理最佳

产量和氮肥利用率分别比对照的提高9.43%和24.69%

达到显著水平;各控释掺混处理0-60cm土壤都保持较高的硝态氮含量

至后期较常规施肥的略高

满足了玉米的生长。玉米各时期土壤铵态氮含量大致以高控氮比处理的含量高

差异不明显

但显著高于常规施肥处理的。控氮比50%处理更适合本区域玉米生产。

Abstract

Field experiment were carried out on grain yield of summer maize to determine the effect of different proportions of water-base controlled-release coated urea of 60 d release duration combined with conventional urea as topdressing on nitrogen utilization

nitrogen agronomic efficiency

nitrogen partial productivity

nitrogen harvest index and nitrogen accumulation.Dynamic distribution of nitrate content in soil was also studied.The findings indicated that the treatment of controlled-release urea combined with ...
