大豆生育阶段动态模型的研究

STUDY ON THE SOYBEAN DEVELOPMENT SIMULATUION MODEL

研究了不同大豆类型品种的发育与温、光等主要环境因子的数量关系 ,在借鉴吸收析因指数形式的小麦发育期动态模拟模型 (WDSM)、“水稻钟”模型和DSSAT3等模型思想方法基础上 ,构建了大豆生育动态模拟模型 (SDSM)。经验证不同类型品种平均误差在 1 -3天之内 ,与传统的积温法相比 。

In this paper ,the quantitative relationship between soybean development of different types of varieties and main environmental factors (temperature ,photoperiod ,act.) was systematically studied.The soybean development simulation model(SDSM) was estoblished based on the thoughts of the Wheat Development Simulation model(WDSM) expressed by a multiple form of exponential functions and the Rice Clock Model and the DSSAT3 Model .Appling the SDSM , mean error of different soybean varieties was in 1-3 days The precision of the SDSM is higher than traditional accumulative temperature method.shedbasedonthethough
