摘要: 如何提高肥料利用率、减少由于肥料损失带来的环境污染是长期以来全球共同关注的课题。针对我国肥料利用率低、氮肥损失严重的现状,本文综述了除传统提高肥料利用率技术以外的几项其它技术的最新研究进展,主要包括应用实时、实地氮肥管理技术快速、无损检测作物氮素营养状况,进行作物推荐施肥;研发新型缓/控释肥料,调控肥料养分的供应;运用农田养分精准管理技术,因地制宜、精细准确地施用肥料;通过脲酶抑制剂或硝化抑制剂,有效地抑制NH3挥发和NO3--N淋溶损失等。并对今后提高肥料利用率技术进行了展望。

关键词: 肥料利用率, 实时、实地氮肥管理, 缓/控释肥料, 农田养分精准管理技术, 脲酶/硝化抑制剂

Abstract: How to increase fertilizer use efficiency (FUE)and decrease environment pollution caused by nutrient losses has been concerned by the whole world for a long time. It is very important to increase FUE in China for its low FUE and serious losses of nutrient. The recent advances of the technologies to increase FUE are reviewed in this article, which include applying site-specific nitrogen management and real-time nitrogen management to fertilizer management, development of new style slowly release and controlled release fertilizer to control nutrient release,technology of site specific nutrient management and using urease inhibitor or nitrification inhibitor to decrease nitrogen losses. And some technologies to increase FUE are previewed in the future.

Key words: Fertilizer use efficiency, Site-specific/real-time nitrogen management, Slowly release/controlled release fertilizer, Site specific nutrient management, Urease/nitrification inhibitor
