Research And Application Of Precision Fertilization Big Data System

Precision fertilization has the effect of improving the utilization rate and economic benefit of fertilizer and reducing the effect of fertilizer on the environment.Since Guangdong province in 2005 to carry out soil testing and fertilization work,has accumulated a large number of data.How to use these results to establish a large database of fertilization in the Province,to achieve precise fertilization,and promote the application in our province,has become one of the key technologies to improve the prec ision fertilization information.With the rapid development of big data technology,GIS technology and mobile Internet,and the integration of big data technology a nd GIS technology,it is possible to establish the precise fertilization system,provide new solutions and ideas for big data application and management,precision fertilization decision,agricultural technology promotion.In this study,according to the actual situation of fertilization in Guangdong province big data,using big data technology and Web GIS technology,a set of Precise Fertilization data system and corresponding information service platform are developed and integrated with agricultural fertilization decision-making,agricultural technology promotion,fertilization data visualization etc,and the system is applied in our province.The conclusions are as follows:(1)From the analysis of the target user groups,giving the overall system use case model,useing the RESTful architecture and distributed cluster architecture,combined with big data technology and Web GIS technology and Arc GIS Server,gaode map API,ELK platform,the overall framework of the main functions of the system is designed.(2)Based on the Precise Fertilization of big data,including the 96 County agricultural land use data,soil nutrient data,farmland crop distribution system and our province main crops fertilization index system,the precision of crop fertilization model,through data processing,cleaning,conversion,storage,the standard unified precision fertilization database is established,and the integration of spatial data and non spatial data isrealized.With the help of Hadoop architecture to achieve large data storage and analysis,a theoretical basis for precision fertilizationisprovided.(3)The system has been developed and applied to the main functions,including fertilization decision service,GIS basic function,spatial orientation,expert consulting services,agricultural knowledge base,agricultural data management,agricultural statistical data analysis,user management etc.(4)The system has been popularized in the agricultural counties of the province of 96 and it is awardedasanexcellentcasefor2016-2017 years of modernization of Guangdong governance and governance capability.The application shows that the system is suitable for the actual situation of precision fertilization in our province.Assuming that the 30 million acres of arable land in Guangdong province to promote the application of per mu can save fertilizer by up to 30%,increase the yield of 15%.It will produce 4 billion 500 million of the annual benefits.
