石河子大学 信息科学与技术学院毕业论文 课题名称： 基于Android的玉米病虫草害诊断 系统的研究 学生姓名： 学 院： 信息科学与技术学院 专业年级： 信息管理与信息系统2007级 指导教师： 完成日期： 二○一一年六月八日 基于Android的玉米病虫草害诊断系统的研究 [摘 要]玉米是我国重要的粮饲作物及工副业原料，近年来，玉米病虫草害发生有明显上升趋势，仍是限制玉米产量增加的重要因素。玉米生产与植保专家时空分布不对称，农业生产第一线缺少包括植保专家在内的农业专业技术人员的实时指导，是导致玉米病虫草害发生并限制玉米增产的原因之一[1]。随着农村信息化进程的深入推进，智能通讯设备迅速普及，利用智能手机为载体，编写农业专家系统软件，使得生产一线技术人员及农户及时对玉米病虫草害进行诊断和防治已刻不容缓。我们通过对玉米病虫草害的发生及其防治现状的研究，运用Java语言和SQLite数据库开发一个基于Android的玉米病虫草害诊断系统，用于生产一线技术人员及农户对玉米病虫草害实时诊断，以提高玉米产量及质量。本篇论文以该系统的分析、设计和开发的全过程为主线，给出基于Android的玉米病虫草害诊断系统的设计和技术实现过程，讨论了设计该系统时的思想、方法和过程。 [关键词] 病虫草害 诊断 图像 推理 Android The corn ill Chinese caterpillar fungus diagnosis system based on Android Students：Cheng Ze Cheng Hongxia Teacher：Dai Jianguo [Abstract] Corn is an important forage crop, industrial and Sideline raw material in China.. In recent years, the increasing trend of maize disease Chinese caterpillar fungus is still a significant factor on increasing maize yield. Corn production, eppo expert’s time-space distribution asymmetry and lacking of the real-time guidance of in front-line agriculture experts is the reason that corn ill Chinese caterpillar fungus happen and limit maize yield increasing. With the deepening of rural information process, the intelligent communication equipment rapid popularization, using smart phones as the carrier, writing agricultural expert system software, make producing technical personnel and the farmers of maize disease Chinese caterpillar fungus in time for diagnosis and prevention has is urgently needed. We through the ill Chinese caterpillar fungus of maize occurrence and control, use Java language and based on android to develop a SQLite database of corn ill Chinese caterpillar fungus diagnosis system for producing technical personnel and corn farmers on real-time diagnosis ill Chinese caterpillar fungus to improve the maize yield and quality. This paper to this system analysis, design and development entire process as the main line, give the corn il
