| 摘 要： | 农业中氮肥的不合理施用造成氮肥利用率下降并引发严重的环境问题,已引起国内外广泛关注。从农业中肥料利用率的科学本质及其试验设计原理出发,讨论了如何筛选和利用长期试验和大田生产试验资料评价肥料利用率以及肥料试验中施肥量、氮磷钾施用比例与氮肥利用率评价的问题,并提出在农业中应考虑施肥与增产的实际效应以及用不同养分肥料的配合施用来设计和分析施肥实践中氮肥利用率的观点。

| Abstract: | The ever decreasing use efficiency of N fertilizers and the resultant severe pollution to water body in China has been given great concerns globally.On a basis of concept,assessment and experimental approaches of fertilizer use efficiency,how to screen the fertilization data from field experiments and conventional farm managements,howto assess N use efficiency from field fertilization rates experiments,nutrient ration with balancing and how to design a fertilization rate with rational nutrient ration for hi... |
