[Objective]The research aimed to provide reference for the selection of afforestation land and the scientific management of soil.[Method] Established partial least squares regression model with wavelet denoising to study the main factors of soil on the growth of paulownia plantation.[Results] Paulownia had the significant or very relationship with about all factors of soil.The main facors influenced the growth of paulownia was available phosphorus and organic matters.[Conclusion] The partial least squares regression model is reasonable and accurate,with determinate value in use.
