摘要: 如何提高肥料利用率、減少由于肥料損失帶來的環境污染是長期以來全球共同關注的課題。針對我國肥料利用率低、氮肥損失嚴重的現狀,本文綜述了除傳統提高肥料利用率技術以外的幾項其它技術的最新研究進展,主要包括應用實時、實地氮肥管理技術快速、無損檢測作物氮素營養狀況,進行作物推薦施肥;研發新型緩/控釋肥料,調控肥料養分的供應;運用農田養分精準管理技術,因地制宜、精細準確地施用肥料;通過脲酶抑制劑或硝化抑制劑,有效地抑制NH3揮發和NO3--N淋溶損失等。并對今后提高肥料利用率技術進行了展望。

關鍵詞: 肥料利用率, 實時、實地氮肥管理, 緩/控釋肥料, 農田養分精準管理技術, 脲酶/硝化抑制劑

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
