Photosynthesis and dry-matter partioning are main procedures in crop growth and development models. In this paper, a model is presented based on experiment of sweet potato variety Xushu 18.
Based on simulated model of JiangNan Double Crop rice, growth and development status of early rice effected only by climate condition in ChangDe Area from1961to2000were simulated respectively.
以江南双季稻生长评估模型为工具，模拟了常德地区1961 - 2000年早稻的生长状况。

Build a good crop growth and developmentmodel, not only can predict the crop in different environmental conditions, most need to re-estimate the model parameters and optimization.
