Research And Development On The Decision Support System For Rice-crayfish Integrated Farming Based On Java

The rice-crayfish integrated farming is one of the emerging industries that promote the revitalization of rural industries and the structural reform of the agricultural supply side.The paper aimed at the realistic demand of informationized and intelligent decision-making platform for rice-crayfish integrated farming nowadays,with the support of the theoretical knowledge concerning rice-crayfish integrated farming,be based on Java and XML languages and software such as PhotoShop CS6 and exe4j,went through the procedures of system requirement analysis and feasibility analysis,information collection,element analysis,model analysis,UI design,function design,code compilation and other procedures,eventually developed a decision support system specialized in rice-crayfish integrated farming,which was a dual-platform of standalone version and mobile version.The system provides an informationized platform for the promotion and application of the green and efficient techniques of rice-crayfish integrated farming.The main findings are as follows:(1)Based on the rice leaf age model,population quality,precise quantitative cultivation,the growth and development pattern of crayfish,ecological and healthy breeding technique and the related achievements of rice-crayfish integrated farming,the knowledge base and database covering historical evolution and industrial status of rice-crayfish integrated farming,technical specifications,expert knowledge,variety introduction and product information have been established.The decision-making model library has been innovatively constructed,including rice basic seedlings calculation,precise fertilization,disease and pest control under rice-crayfish continuous cropping mode,with crayfish seedlings input,feedstuff feeding,water quality evaluation,disease and pest control,and calculation of common economic benefits.A strict system logic architecture has been formed to create prerequisites for the development of rice-crayfish integrated farming decision support system.(2)Based on the Java object-oriented programming language and its platform,combined with the related achievements about rice,crayfish and rice-crayfish integrated farming,the standalone version and mobile version of rice-crayfish integrated farming decision support system have been integratedly developed.The above-mentioned systems integrate basic knowledge popularization,precise decision support,relevant product recommendation,expert knowledge acquisition,practical tools,system help,and program user manual.After testing and application,the systems have a friendly interface,informative content,strong functional usability,reliability and maintainability.The systems have obtained the computer software copyrights of the National Copyright Administration(2019SR1369214,2020SR1613507 respectively),which are the high-quality informationized platforms for novel agricultural business entities to conduct independent learning and decision-making.
