摘要：病虫害的诊断和防治是保障农业安全生产的重要环节，诊断的实时性和防治的有效性是必须解决的首要问题。本文建立了基于Android的互联网植物医生服务平台，创建了农作物病虫害数据库、诊断规则库，并通过基于Android智能手机的植物医生APP提供农业病虫害专家远程诊断和基于专家系统的自助诊断，建立了全天候的病虫害诊断服务模式，使农民“足不出户”即可得到植保专家的防治指导，解决作物生产过程中“求医难”的问题。另外，专家还可根据农民咨询的情况，对病虫害的分布与发生进行分析预警。

Abstract The diagnosis and prevention of diseases and pests is an important link to ensure the safe production of agriculture. Real-time diagnosis and effectiveness of prevention and cure are the primary problems that must be solved. In this paper， an Android-Based Internet Service Platform of plant doctor is established. The platform creates database of plant diseases and pests， and diagnoses rules. Through the remote diagnosis of plant pests and diseases and the self-diagnosis of expert system based on the plant doctor Android APP， the all-day diseases and pests diagnosis service mode was established. This mode can ensure farmers get the prevention and cure guidance from plant protection experts without leaving the fields， and solve the problem of difficult to get crop protection guidance. In addition， experts can also analyze and predict the distribution and occurrence of diseases and pests according to the farmers consultation.

病蟲害是我国农业生产的主要灾害之一，防治不及时易造成较大的经济损失[1]，是农民关注的重要问题。病虫害的实时、准确诊断是对其进行及时有效防治的关键。随着互联网技术的快速发展，远程诊断已被广泛应用于农业病虫害防治方面。作物病虫害的远程诊断方式主要有基于专家系统[2]和基于面对面交互式[3]两种。如北京市蔬菜病虫害远程诊治专家系统[4]、葡萄病害智能决策支持系统[5]、广西玉米病虫害诊断决策专家系统[6]、玉米病害诊断系统[7]、黄瓜病害诊断系统[8]等，均为基于专家系统的远程诊断；而作物病虫害专家在线视频诊断系统[9]、果树病虫害可视化诊断系统[10]、农技专家远程诊断系统[11]等，均为基于面对面交互式的远程诊断。……
