梨园种植施肥管理系统
摘要
我国身为农业大国，但在果树施肥方面仍存在诸如施肥结构缺乏科学依据、施肥用量过量或不足以及缺乏统一标准等一系列问题。为改善我国果 *51今日免费论文网|www.jxszl.com +Q: ^351916072# 
业存在的盲目施肥问题，本设计以梨园作为研究对象，以养分平衡法作为施肥方法，利用Android Studio实现移动客户端开发，利用​eclipse进行web端管理平台的开发，并利用Naicat工具对MySQL数据库以可视化方式进行设计，加之以开源数据集和百度地图的二次开发技术作为支持实现梨园施肥管理系统的研发。本设计在实现了：（1）Android app：全国梨园分布地图以及梨园附属信息（包括土壤属性，果园属性，往年施肥相关信息等）的展示；平衡施肥模型的构建。（2）Web管理平台：用户管理；施肥管理；果园管理；梨品种管理，权限管理。本设计运用精准施肥中的养分平衡法构建模型，确定施肥量和比例，节约了成本，增加了增产增收的可能性，管理系统在双端的实现既可以解决科学的施肥的方法在农户的普及度较低的问题，又方便管理员管理，但过于依赖人力物力的数据采集已经无法满足我们的需要，若能得到合理的管理，将为果农带来无限福音。

MANAGEMENT SYSTEM OF PLANTING AND FERTILIZATION IN PEAR GARDEN
ABSTRACT
China is a large agricultural country, but there are still a series of problems in the fertilization of fruit trees, such as the lack of scientific basis for fertilization structure, excessive or insufficient amount of fertilization and the lack of unified standards. In order to improve the problem of blind fertilization in Chinas fruit industry, this design takes the pear garden as the research object, the nutrient balance method as the fertilization method, and uses Android Studio and eclipse develop the mobile client and web management platform respectively, use MySQL design the database, and use the secondary development technology of open source data set and Baidu map as the support to realize the research and development of fertilizer management system in pear garden. This design realizes: (1) Android App: the display of the distribution map of the national pear garden and the auxiliary information of the pear garden (including soil properties, orchard properties, previous years fertilization related information, etc.); the construction of the balanced fertilization model. (2) Web management platform: user management; fertilization model parameter management; orchard management; pear variety management, authority management. In this design, a more scientific method is used to determine the amount and proportion of fertilizer application, which saves cost and increases the possibility of increasing production and income. The realization of the management system at both ends can not only solve the problem of low popularity of scientific fertilizer application method in farmers, but also facilitate the management of administrators, However, the data collection needs more human and material resources Strong support, if can get reasonable management, will bring infinite gospel for fruit farmers.
