摘　　要： 在分析了影响广东省优质稻栽培的因素及相互作用关系和收集完整的技术参数的基础上,运用农业系统工程分析的原理和方法,总结与汇集专家的施肥经验,依靠各种基础资料数据库,研制出"优质稻高产优化施肥与栽培配套技术专家系统".该系统采用人机对话形式,根据用户提供的相关参数,由电脑进行推理、预测预报一年两季水稻的栽培密度、施肥量及肥料产中分配比例,并打印出技术操作清单,交由农户执行,操作简便,易于推广. Based on analysis of factors on fertilization of rice and reciprocity of these factors, with the method of system analysis and engineering, an expert system was developed based on the fertilizing experience of expert in agriculture and the agronomic database,which aims to optimize fertilization and planting. With parameters of soil fertility, soil character, planting season and rice species input by user via man-machine conversation, the system can be used to predict the yields of rice and tell the users the amount of nitrogen fertilization, phosphate fertilization and potassium fertilization. 
