畜禽粪便氮基成分的近红外预测模型研究

nimal manure is an important biomass resource and its efficient use of animal mnaure depends on the known nitrogen-based nutrient contents in animal manure. Near infrared spectroscopy (NIRS), as one of fast, convenient, non-destructive methods, has been widely used for rapid evaluation of nirogen-based composition in animal manure. This study reviews recent advances on NIRS calibration models of animal manure nitogen-based compostion. Future prospects and needs related to increasing the feasibility of the industrial application of NIRS and improving NIRS prediction precision in determining nitrogen-based nutrient contents of animal manure are also discussed
