摘    要:为了筛选出简便、实用的硝酸盐快速诊断技术,使实时监测植物氮素含量水平成为可能,对离子选择电极法与硝酸盐试纸法2种诊断技术进行综述,对比了其在工作原理、精度、存在问题和提高精度的途径等方面的研究现状.结果表明:2种方法都存在一定的干扰因素,并且尚无简便有效的消除方法;离子选择电极法受干扰因素影响更大,测量精度和测量稳定性低于硝酸盐试纸法;分析了硝酸盐快速诊断技术在植物氮素营养诊断领域的应用前景.为促进该技术的推广,在取样规范化、干扰因素分析研究、建立特定诊断体系以及降低诊断成本等方面提出了研究建议.

关 键 词:氮素  硝酸盐  快速诊断

Abstract:This paper is to review nitrate quick diagnosis methods.There are two nitrate quick diagnosis techniques of ion selective electrode and nitrite test paper.Both methods are different in their theory,accuracy,current problems,accuracy and interference factors.It is difficult for both to reduce the interference.In particular,the ion selective electrode is readily influenced compared with the nitrate test strips.The accuracy and stability of ion selective electrode are thus lower.It is analyzed for the potential of practical application of these methods.Some recommendations are given in future work such as sampling,interference reduction,specific diagnosis system and and cost reduction.
Keywords:N  nitrate  quick diagnosis
