摘要
硝化抑制剂施用后其显著的农学效应、环境效应和生态效应已得到许多研究的证实,但其施用效果受多种因素的影响.本文从硝化抑制剂施用对土壤氮素转化、硝酸盐淋溶损失和温室气体排放、作物氮素利用、农产品产量和品质以及其他养分有效性的影响等几个方面进行综述,并分析影响其施用效果的因素和评价标准.
The agronomic,environmental,and ecological significances of applying nitrification inhibitor（NI）have been demonstrated by many researches,but the efficiency of NI application was affected by many factors.In this paper,the effects of NI on soil N transformation,nitrate leaching and greenhouse gases emission,fertilizer N use efficiency,yield and quality of agricultural products,and availability of soil nutrients besides N were reviewed,and the factors affecting the efficiency of NI application as well as the evaluation criteria of NI were summarized.
