With the urgent demand of agricultural information for farmers and quick development of telecommunications industry in china, the convenience, quickness and validity of agricultural information service are becoming more important. Now, the problem of the digital divide between rural and urban areas comes from the shortage of effective information transmission means. But the agricultural information services limited by network bandwidth and geography will be changed completely with the mobile phone network coverage to rural areas, especially TD-SCDMA network into rural areas in china. The paper will introduce the development of the 3G technologies-based effect on the agriculture informationization, and discuss the problems of agricultural information resource integration and service adapted to 3G technologies in detail, based on which a 3G technologies-based agricultural information resource application mobile service hierarchy (3GAIMSH) is provided.
