The Development Of The Cotton Balanced Fertilization Experts Decision-Making System Based On WebGIS Of Shehezi Region In Xinjiang

Cotton is not only the most important fiber and oil crops but also the materials of textile, chemical and strategic. So it is the necessary to increase production of cotton to increase farmers income and to meet needs of the national economic development. Cotton balanced fertilization is an important technical measure to increase the yield of cotton. Using computer programming to development cotton computer recommended decision-making system is the effective technical measure to popularize balanced fertilization. With the popularity of network technology, running on the network platform of computer-assisted decision-making cotton fertilizer recommendation system will be more widely used.The study took the agricultural test of Xinjiang Academy of Agricultural and Reclamation Science of Xinjiang Shihezi as the test base, using its test data, soil information data, soil fertilizer and plant nutrition theory, converging the experience and research findings of the experts to found the cotton balanced fertilization expert decision-making system based on WebGIS which used new data treatment technology and geographic information, fully reflected in the number of field management of new ideas.Aimed at the soil fertilizer, texture type, SQL query, irrigation ways, in accordance with needed fertilizer water law of the cotton to found the fields as the basic unit based on WebGIS the cotton balanced fertilization expert decision-making system making topic map, fertilizer recommend and remote system maintenance data management in one.In the process of establishing the system we designed a system to develop the objectives and tasks of the design process, the structure of the system, And then set up a field of GIS data, the parameters of fertilizer and fertilizer recommendation database comprising data, Finally, the system will be divided into navigation information, SQL query, thematic map production, fertilizer recommendation, the five modules to carry out the maintenance of the data and compile the formation of programming based on the WebGIS cotton balanced fertilization expert decision-making system.In short, the system in order to ecosystem nutrient cycling and soil and fertilizer-based system, To crop-specific fertilizer formula as the carrier, Comprehensive use of subtraction poor soil fertility, nutrient balance and fertilizer effect function, Through comprehensive evaluation, analysis and verification of the established system of multi-purpose fertilizer. It not only improved the accuracy of decision-making fertilizer and is highly practical.
