Abstract: Fertilization is an important measure to increase the production of natural rubber. Implement the technique of accurate application of fertilization will help to improve the accurate degree of fertilization guidance, fertilization guidance unit area reduced from 100 square kilometers to square kilometer level, will further increase the capacity and efficiency of natural rubber in our country. The thesis has mainly introduced uses GIS, one of the 3S (GIS, GPS, and RS) technologies, unifies web technologies to develop rubber precise fertilization information system based on the WebGIS in Internet and it also has posed the program of designing and developing, and highlight the key technologies and related modules.
