摘要
作物生长模型的构建有利于既有科研成果的综合集成 ,也是作物种植管理决策现代化的基础 ,还是辅助决策的有力工具。本文以荷兰Wageningen ,美国DSSAT ,澳大利亚APSIM和中国CCSODS等作物生长模型研究流派为例 ,回顾了作物生长模型的发展历程 ,论述了作物生长模型的主要功用 。
Crop growth models have been used greatly and efficiently in many fields such as agro-ecosystem research,crop management,and decision-making.Our understanding on the interactions between crop and environment,integration across disciplines,and organization of data would be improved through the utilization of this kind of models.The crop growth models were helpful to make management decisions,such as cultural practices,fertilizers,irrigation and pesticide,as well as soil erosion,agricultural chemicals leach,climate change impacts and regional yield prediction.The development purposes and limitations of the current prevailing crop growth models were reviewed,the prospect of the models in these areas was also discussed.
