| 英文摘要 | Soil samples (n = 68) in long-term fertilizer experiment zones in fengqiu ecology experimental station of chinese academy of Sciences were involved in this experiment. Partial least squares (PLS) and artificial neural network (ANN) models were developed to predict soil available P between Olsen-P and fourier transform infrared-photoacoustic (FTIR-PAS) spectra. The calibration error, validation error and calibration coefficient (R-2) from partial least square (PLS) model were 1. 79 mg/kg, 5. 25 mg/kg and 0. 96, respectively, and from the ANN model were 2. 40 mg/kg, 5. 43 mg/kg and 0. 84, respectively. The calibration statistics show these two modes can be used in the prediction of soil available P, and the prediction from PLS model is better than that from ANN model. This prediction method is non-destructive, and no pretreatment is needed, which make FTIR-PAS a promising method for fast determination of soil available P. |
