| Since the development of soil testing and formula fertilization in China,the development of precision fertilization technology has gradually matured,and has been continuously integrated into cutting-edge technologies such as global positioning systems,geographic information systems,Internet technologies,and sensor technologies.At present,it is in a critical period of winning a well-off society.A series of contradictions between people and land are prominent,such as the aging of the agricultural population,the limited amount of cultivated land,the insufficient per capita cultivated land area,and the fragmentation of cultivated land.The application of precision agricultural fertilization technology can increase crop yields and reduce Environmental pollution will effectively protect China’s food security and promote sustainable agricultural development.However,in the actual research,precision fertilization has the problems of emphasis on research and light application;emphasis on theory and light technology,and less practical products are applicable.On the basis of summarizing the development process and current status of precision fertilization applications at home and abroad,this paper develops a big data precision fertilization micro-application to rapidly promote precision fertilization technology,and solves the problem of difficult application of precision fertilization through the results of this research.Users can scan and use codes across platforms without downloading and installing,and it is easy to operate.The promotion in a wide range can minimize the promotion cost and increase the adoption rate of precision fertilization technology.This research takes Guangdong Province as the research area and combines geographic information system,big data technology,and Springboot microservice framework for micro application development.The research content is as follows:(1)Based on the ER data model,the mdb geodatabase is used to store ten million-level land soil data,land-use data,and sampling point data in Guangdong Province.After spatial processing such as spatial interpolation and standardized processing,accurate county-toprovincial level Fertilization thematic maps were then released as WMS map slicing services.Use Arc GIS API For Java Script for secondary development of Web GIS to form a GIS service module.(2)Define the target users and business needs,and use SQl Server to complete the construction of the business database.Use Spring Boot microservice framework to design and develop "high cohesion,low coupling" service module development,and provide Restful style access interface.At the same time,the geographic database and the fertilization model are coupled to implement the WEB forwarding function of the GIS module.In addition,the Hadoop platform is used for big data visualization analysis of nutrient data across the province to provide support for accurate fertilization decisions.(3)Introduce third-party Baidu Map API and Hefeng Weather API,and complete microapplication development through We Chat mini-program development platform to achieve GPS real-time on-site precise fertilization based on plot location,agricultural information,fertilization quiz,agricultural knowledge base,and personalized services And other functional modules.This application has been recognized by many experts in the agricultural field.After sampling and verification of the "3414" soil testing formula fertilization data,it can basically meet the actual needs of precision fertilization in Guangdong Province.Through the preliminary preparation and accumulation,it won the third prize of the 2019 National We Chat Mini Program Application Development Competition.It will be promoted in Guangdong Province.It is expected to save more than 20% of fertilizer application and increase output by more than 10%,which will generate huge economic and social benefits.At present,the research results will be carried out through the livelihood service section of "YUE SHENG SHI" micro application online. |
