| Abstract: | Some universal limitations,such as the incomplete agriculture knowledge,deficient ability in data analysis and processing,etc,were found in the existing agricultural technology service system.The agricultural technology service knowledge system discussed in this article was constructed to dealing with these problems.Some technology bottlenecks in the process of system construction,including the construction of agricultural sustainable development system,the agricultural knowledge expression method,the evidence uncertainty reasoning with multi parameter,etc,were discussed based on the in system development case. |
