摘要： Establishing mathematical models of crop growth plays an important role in development and management of modern plant production systems. In this paper, variable regulation models were carried on ' Cara Cara' red navel orange [ Citrus sinensis (L.)Osbeck ] to study the dynamic laws of growth of flowers, leaves, fruits and shoots, as well as the periodic changing laws of nitrogen content in leaves, leaves size-increasing and falling and fruits development. And the relationship between crop growth and yields was also analyzed. Results showed that the dynamic changes of flower and fruit numbers of ' Cara Cara' red navel orange could be modeled with Weibull frequency distribution; the development of fruit size presented " S" curve; while nitrogen content in spring leaves presented modified exponential distribution; the diameters of spring and autumn shoots were both highly correlated with developmental time, which could be described by power function distribution models respectively; the relativity of flower numbers and fruit numbers on autumn shoots in the following year could be described by logarithmic regression model.
