| Abstract: |
| The research ideas of crop productivity potential were recommended and the developmental history and current situation of the research of the yield were reviewed. The applied questions of empirical models and physical-based models were discussed in this paper and the strongpoints and shortcomings of both methods were assessed ．It was pointed out that the research of crop productivity potential should be linked with natural factors and social economic and technical factors but not only natural factors；The perfectness of physical-based models also needs much data-base and the help of correlative techniques. Crop productivity potential will be more important in agricultural productivity along with further researches. |
