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,构建了大豆阶段发育动态模拟模型(SDSM)。经验正不同类型品种平均误差在1-2d内,与传统的积温法相比,其模拟精度有了较大提高。
The relationship between the development of different soybean varieties and the major environmental factors such as temperature and light was studied. Based on the models of dynamic model of wheat development (WDSM), “Rice Bell” and DSSAT3 Based on the method, a dynamic simulation model of soybean stage development (SDSM) was constructed. The experience is different types of varieties of the average error within 1-2d, compared with the traditional accumulation method, the simulation accuracy has been greatly improved.
