摘要
在搜集整理大量玉米病害资料和实际调查的基础上,利用My SQL系统数据库和PHP语言编程设计了集玉米病害信息管理、信息检索、病害诊断等功能于一体的玉米病害检索诊断系统。该系统以面向对象的设计思路,基于多叉树遍历算法进行玉米病害推理诊断,极大地降低了用户的输入负担,提高了病害推理诊断速度,降低出错概率。系统突出强调算法的优化处理,分析并优化了数据库的"时-空"效率,提高数据处理速度并且降低数据占用空间,同时注重在线数据的安全性。
On the basis of a large number of maize disease data and actual investigation,using the My SQL database and PHP language,a maize disease diagnosis system was designed integrating functions of maize disease information management,information retrieval,disease diagnosis,etc. With the object- oriented design ideas,reasoning based on quadtree calendar calculation method,this system greatly reduced the input burden of users,enhanced the disease diagnosis reasoning speed,and reduced the error probability. The system emphasized the optimization of algorithm,analyzed and optimized the"space- time"efficiency of database,improved the data processing speed and reduced the data space occupation. At the same time,it paid attentions to the safety of online data.
