To find a solution to poor generality and reusability of crop growth model, the framework of greenhouse crop growth simulation model was established based on Agent. The structure and function of model Agent, management A⁃gent, communication Agent, and communication transport system and model catalog service agent were analyzed. Based on XML, the communication between Agent and catalog service system was achieved. And the model was described based on program logic mixed ( PLM) method. Based on JADE platform, the software for greenhouse crop growth simulation model was developed. The system could realize the simulation of cucumber growth.%针对目前温室作物生长模型重用性和共享性差的问题，建立了基于Agent的温室作物生长模拟系统，分析了模型集成的模型Agent、管理Agent、通信传输系统和模型目录服务器的结构和功能，建立了基于XML的温室作物生长模拟Agent、目录服务器和Agent间通信表示方法，采用程序⁃逻辑混合（ PLM）方法实现模型表示。以JADE平台为基础，开发了温室作物生长模拟系统软件。以黄瓜生长模型进行了系统测试，结果表明本系统所建立的温室黄瓜生长模型能实现温室黄瓜生长的模拟。
