摘　　要：随着农业专家系统的不断完善,农业专家系统已经逐渐成为现代农业生产中一个良好的辅助工具。针对目前我国网络铺设农村覆盖率较低以及农民的实际知识水平不高的情况设计开发了农业专家系统语音服务平台。采用剪枝技术解决了知识库中的数据量大、推理速度慢的问题。设计的剪枝技术,"剪掉"了用户在查询过程中那些与用户无关的知识,从而在推理机对用户请求的知识进行推理之前,精简了决策树的结构,加快了推理速度。With the constant perfection of agricultural expert system, it has gradually become a fine auxiliary implement in modern agricultural production. In view of the lack of the network in rural China and the lower educational level of farmers, the paper designed the pronunciation service of agricultural expert system platform. Scissors branch technologies were used to solute the problems of large amount of data and low speed of reasoning in knowledge bank. This method cut down the irrelevant knowledge to consumers in inquiry process thus simplifing the structure of decision tree and accelerating the reasoning speed before reasoning machine carried out reasonings that consumers requested.
