积累

The critical nitrogen content in heading period was used to calculate the biggest accumulation quantity of nitrogen. The latent distribution index of leaf and stem, which was the variety heredity parameter, were used to distinguish the difference in nitrogen assignment in different varieties. The dynamic content of the nitrogen accumulation before anthesis could be described with a Richards model. The dynamic content of the nitrogen remobilization in leaf with leaf area index could be described with a power model, and the nitrogen absorption of grain from soil with dry weight could be described with a power model. The dynamic content of nitrogen density in stem and spike with physiological development time could be described with a nonlinear model.

With the parameters varies within the range of our study, the simulation results compared with their corresponding monochromatic output show that: the wavelength accumulation effect upon the output is small; therefore, it is reasonable and feasible to employing the monochromatic model to deal with the BGOCS systems with broad-band source; the difference between the accumulation output and the monochromatic output decreases with the increase of the current to be measured in the total wavelength accumulation effect; the effect of the Verdet constant is the greatest, that of the Reflection-Induced-Retardance is intermediate, that of the linear birefringence is the smallest.
