The Soil Fertility Information Management In Cotton Field And Experts Fertilizer Decision System Based On The Middleware Technology

Producing the different conditions of different crops and varieties because a variety of climate and vast territory in china. According to the local needs of of different varieties of the actual soil conditions to manage, Due to the agricultural production complex and ecological regional, there must have a sound and the huge promotional system. Information technology can be provided for promotional system and staffs by using the most advanced tools and techniques.As the accessible, efficient and reproduce the characteristics in the dissemination of information and knowledge, a great number of scientific and technological achievements were rapidly spread to the hands of the farmers. It realized large-scale application, and covered and overcame the shortage of agricultural scientists. Meanwhile, it changed the traditional model of agricultural science and technology extension. Thus, it can greatly promot the development of agricultural production and the technical achievements of the transformation and local scientific production organization.According to the important role of the soil fertility information, networking and the resources sharing in the agricultural production, using the examples of the Xinjiang Production and Construction Group 147,149,150, by using the middleware technology, the database technology, JSP technology and SQL Service technology to set a fertility network framework; According to the regional soil fertility, texture, and with the land for the operating unit. Buliting a soil fertility management information system for cotton field including in the soil nutrient management, SQL Information and online decision-making functions. System design:1. Collects in 2004 147 groups,149 group,150 group soils samples attribute information(il type, nitrogen, phosphorus, potassium, organic quality), the fertilizer information(Chemical fertilizer name, nutrient contents, chemical property, accommodation) and the production condition information(Field area, per unit area yield, mu of apply fertilizer expecting that, front stubble crop), take SQL 2,000 as the development kit, take the terraced fields as the basic appraisal unit, establishes including the database module is the terraced fields soil fertility information inquiry module, the terraced fields soil fertility information statistics module, the terraced fields according to area classification administration module soil nutrient information synthesis management database.2. Based on the middleware technology agreement, the database basic processing logic seal in the JavaBean package, transfers through JSP the JavaBean realization database the connection; By the J2EE frame technology, use widespread JSP/Servlet the server Tomcat server to seal the database as the middleware vessel to form the data pool.3. Take the Xinjiang army corps oasis agriculture ecology key laboratory newest fertilizer test model and the parameter as a core, uses the formula to apply fertilizer the goal to produce, take the soil nutrient information synthesis management data pool as the base, In-line every data base and build development environment establishes the cotton field soil nutrient information management and the crops recommendation system under the middleware J2 SDK. This system mainly includes the user to land the module, the user registration module, the information inquiry module, the expert applies fertilizer module, the expert consults module, the user registration module, the data management module, the user administration module.4. The system using JSP of middleware link technology to Synthesis picture, word, audio frequency, video frequency, using Macromedia Dreamweaver MX2004 form the chart, the article, the sound and the Web page to build intrnet website. Has realized the long-distance farmland information data browsing, the network SQL inquiry, the database long-distance management and recommendation, on-line decision-making service function and so on maintains and applies fertilizer.The system based on the middleware technology provides the regional soil fertility condition and monitors the dynamic changes in information for the agricultural production units of the Corps forefront, and provides the information decision support for the fertilizer production, allocation, and the marketing departments. It will help farmers make scientific decisions according to the mrket condition, Implement agricultural production and making the management and operation scientific, overcome blindness, and increase agricultural production and intensive management. On the basis, forecasting the prospect of soil fertility management information services and decision-making fertilizer in the agricultural system. It is very important to further enhance the scientific fertilization and fertilizer use efficiency for farmers, increase income, as well as protect environment.
