RICEMOD: A Physiologically Based Rice Growth and Yield Model

摘要

A synthesis or crop modeling approach is helpful in studying rice crop growth and yield as a system. RICEMOD is a rice crop simulation model developed in 1979 as a tool for assessing rice research needs. This paper describes RICEMOD's development from a relatively simple model for rice growth and yield under luxury nitrogen and water conditions to its current state in which many physical and physiological aspects of crop water deficits have been incorporated. Part I describes the structure and function of the initial physiologically based simulation model. Part II illustrates soil physical and plant physiological components incorporated to give RICEMOD soil and plant water balance capabilities, extending its potential use to rainfed rice research. Part III compares the model output with experimental data in which soil and plant water status were monitored during water stress.
