Abstract  

 Based on fertilizer experimental design, an optimum model is established with spectrum characteristics for estimating winter wheat yield and deteming the relivant optimum period. The reflection ratio and its vegetation indices are important forecasting factors. In the study of nitrogen and phosphrus, TM1-4 and combinations of NTR and TM1-3 are all used as preminary factors to establish the model. In the models of wheat yield,N and P are introduced as variables.

Key words:  Fertilizer design of wheat       Reflectance spectra       Optimal model
