石河子大学 信息科学与技术学院毕业论文 课题名称： 基于WEB的加工番茄氮素优化管理精准控制系统研究 学生姓名： 学 院： 信息科学与技术学院 专业年级： 计算机科学与技术2007级 指导教师： 完成日期： 二〇一一年六月五日 摘 要【摘 要】随着我国种植业结构的调整，新疆番茄生产面积也迅速增加，尽管我国蔬菜产业有较大发展，但存在的问题也很突出。从作物特点来看，番茄作物本身对水分和养分需要高，但目前很多地区种植番茄生长在低温、弱光照、次生盐渍化及土传病害等严重逆境环境中，与高产优质的生产目标还有很大距离。该系统主要包含了番茄推荐施肥系统的设计思想和实现技术，该系统将Delphi技术、SQL Server2000数据库技术和人工智能理论有机地结合在一起。是将计算机技术应用于农业专家系统促进精准农业的有益尝试，同时本系统有很强的可扩充性和良好的跨平台性，有良好的应用前景。本系统主要讲述番茄施肥配方系统的主要系统结构和功能模块。此软件主要服务于新疆番茄种植中施肥的各个环节，由该系统对番茄的不同生长期进行施肥决策与推荐，实现科学种田，以达到省水省肥减少用户的投资增加收入的主要目的。 【关键词】番茄氮素；精准控制；精准控制系统 Abstract 【Abstract】With Chinas cropping structure adjustment, the injiang tomato production area also increases rapidly, despite our vegetable industry have bigger problems existing in the development, but also very outstanding. Judging from crop characteristics, tomato crop itself to moisture and nutrients, but now many need high planting tomatoes grow in low temperature area, and the weak light, secondary salinization, and soil spread diseases, severe adversity environment with high quality production goals and great distance. This system mainly includes tomato recommend fertilization expert systems design idea and realizing technology, this system will Delphi technology, database technology and artificial intelligence theory together efficiently. Computer technology is applied to promote agricultural expert system of precision agriculture, while the beneficial attempt this system has strong scalability and good cross-platform-ability, have good application prospect. This system mainly about tomatoes fertilization systems main system structure and function modules. This software mainly serves the planting of xinjiang tomatoes fertilization by this system, various links to the different growth of tomato on fertilization decision and recommend, realize scientific farming, achieves the provincial water provinces fat reduce user investment increase income to be the main goal. 【Key words】Tomato nitrogen; Accurate control; Precise contro
