Research Progress on Spectral Analysis for Component Detection of Farming Manure
The farming manure has great utilizable value and can be used for fermentation.However,the physical and chemical analysis of farming manure need to be performed due to the high emission and complex composition,which can also provide a reference for efficient utilization of farming manure.Traditional physical and chemical detection methods of manure components have many problems,such as time-consuming,complex pre-treatment process,and etc.Nowadays,spectral analysis technology has been carried out in the field of farming manure components detection because of its advantages of low cost and fast detection speed,which shows a good prospect for future application.In this paper,the traditional manure detection method and its shortcomings were introduced.And then,the research progress in the determination of carbon and nitrogen elements,metal elements,dry matter/organic matter and phosphorus elements in farming manure based on spectral analysis technology was reviewed.Finally,the problems and improvement directions of prediction model construction,sample preparation and testing instrument development based on spectral analysis technology were summarized.This paper can provide theoretical support for the rational utilization of farming manure detection.
