Abstract: Based on the analysis of the informatization development status and existing problems of Guangxi agricultural science and technology park, Service Oriented Architecture (SOA) technology was used in this paper to put forward the overall framework design idea, system architecture and working process of the information integrated service platform of Guangxi agricultural science and technology park. The platform used the middleware method to realize the uniform interface of data interaction and the unified access of structured and unstructured data, such as the heterogeneous databases, web service and application resources. Combined with the actual situation of the park, the park public information platform, the park management service platform and the park application service platform have been developed, and a batch of systems were integrated and applied, such as the product quality and safety traceability, the automatic identification and diagnosis of pests and diseases, the remote technical services by experts, and the informatization management of farms. These systems have been popularized and applied in the agricultural science and technology parks of Wuming District, Fusui County, Longzhou County, Heshan City and Wuxuan County, improving the informatization level and coverage of agricultural science and technology parks in Guangxi.
