China is a traditional agricultural country.Agricultural production has a history of thousands of years.The working people have rich experience in agricultural production,but there are few people,less land resources,low utilization rate,low production efficiency,high production cost and environmental Serious pollution and other issues.The level of agricultural productivity and agricultural modernization is related to China's economic and social development.How to develop China's agriculture is worthy of long-term exploration and research.Precision agriculture is a comprehensive system integrating global positioning system,farmland information collection system,farmland remote sensing monitoring system,farmland geographic information system and agricultural expert system.The core is to establish a perfect farmland geographic information system.As a powerful tool for accurately managing the spatial information database of crops,the field information is expressed and managed through the GIS system,which is an important part of precision agriculture implementation.Combining Web technology,Internet technology,database technology and WebGIS technology to construct a precise agricultural grape demonstration park geographic information system is of great significance for the implementation and implementation of precision agriculture.This paper takes the vineyards of Penglai City,Shandong Province as the research area,and combines OpenLayers,geographic information system,ASP.NET MVC,GIS server,management information system and other technologies to construct the precise agricultural management system of the research area.The system adopts B/S mode and uses Microsoft ASP.NET MVC as the system framework.Use the SuperMap's iServer as a map server to publish map services.Implemented in the.NET development environment.The GIS server provides a map data service,and calls user attribute data such as weather,soil,grape strain,and parcel information through a browser.The system has data sharing,map publishing,and land parcel management.At the same time,according to the weather conditions,the existing grape yield data and the increasing rate of grapes give the fertilization suggestion decision for the target yield.Through the statistics of grape physicochemical information,timely grasp the growth and changes of grapes in each plot to achieve refined management of the vineyard.The main work and results of this paper are as follows:(1)In the context of studying the problems encountered in the traditional agricultural production process and the practical significance of promoting precision agriculture under the current situation,taking the vineyards of Penglai City,Shandong Province as an example,analyzing the user interface and data of the precision grape agriculture management information system.And functional requirements to complete system analysis and design;(2)Analyzed the key technologies involved in the Vineyard Management Information System,selected AJAX no-refresh technology to improve the user's web browsing experience,adopted tile map to improve the loading speed of image map,and completed the idea of MVC high cohesion and low coupling.The overall architectural design of the vineyard management information system;(3)Complete the construction of the system attribute database and the geospatial database according to the user's business needs,and solve the storage problem of the system attribute data and the spatial data.The iDsktop 7C is used to make a vector map of the parcel,and the iServer map server is used to publish the vector map to the network to realize the release of the map resources for system access;(4)Select the easy-to-promote and calculate the precise target yield method,and give the fertilization decision of the target yield based on the existing grape basic production data and the grape increasing rate.Through the statistics of grape physicochemical information,we can grasp the growth and changes of grapes in each plot in time to realize the refined management of vineyards.(5)Using Baidu's ECharts data visualization class library,the weather data,soil PH value,vine age,soil PH value,grape sugar content and other information are displayed in multiple angles to overcome the traditional single chart data display mode.Provide more intuitive and informative information to the system user.
