The system realized the functions as basic map handling, information management, cultural plan design, fertilizer and water management, pestdiseaseweed management, suitable dynamic indices design, realtime regulation based on growth status, expert consultation, and system help, etc. Case studies on the system in the rice field experiments in Jiangsu and Zhejiang Provinces, China indicated that the average yield under the precision management plan was 10 464.8 kg/hm2, 12.53% over that in the general plan (9 299.5 kg/hm2). Moreover, the amount of nitrogen fertilizer decreased by 31.5 kg/hm2, as comparing to the general plan. The present work has provided a modeling and systematized decision tool for the design of rice production management prescription, and a basal framework for developing other crop management decision support system.
