Dynamic optimization research on weight increment in winter wheat grain dry matter

GUO Xin yu,YU Ming jian,ZHANG Zhi peng,WANG Li wen,ZHANG Zhuo li(Crop College of China Agriculture University,Beijing 100094,China)  
The stages and levels of grain dry matter accumulation process have been divided by the research of winter grain dry weight.The dynamic characteristic parameters of each stage have been got.The dynamic characteristic parameters also have been studied by the methods of complete collected information concert theory,and the harmonious relationship has been found and optimized with fixed quantity.At the same time:we found that the value of wheat grain dry matter accumulation is mostly dominated by duration in the second stage,and mostly dominated by filling rate in the first stage and last stage.
