#$%^&*AU2020101607A420200910.pdf#####ABSTRACT The present invention discloses a method for rapidly predicting nitrogen (N) and phosphorus (P) content in slurry movement routes of different large-scale dairy farms by comprehensively integrating all factors. The present invention is based on a number of large-scale dairy farms with a typical planting and breeding mode to predict the N and P content in the complex slurry system through field investigation, sampling and measurement of slurry and biogas slurry, spectral collection and mathematical modeling. The slurry system has large quantity, high concentration, contains many suspended particles, and is mixed with straw and sludge, etc. The present invention carries out rapid detection and modeling by near-infrared diffuse reflectance spectroscopy by combining all dynamic influencing factors, including different regions, breeding scales, herd ratios, manure removal approaches and slurry treatment processes. While realizing rapid and accurate quantitative prediction on site, the present invention replaces conventional monitoring procedures, and solves the problem of difficulty in returning the slurry from the large-scale dairy farms to the field, providing technical support for promoting the green transformation of the dairy industry.1/3 Sluryfro : Surrfrom *milking parlors m barns % S- -- ---- - •Biogasplant Storage tank Collection u7Regulating Sedimentat takcollection Slurry tank tank ion tank utkerg Separation Lagoo tank FIG. 1 2.4 2.1 1.8 0 .~1.5 1.2 0.9 4000 6000 8000 10000 12000 Wavenumber/cm-2 FIG. 2
