Precision fertilizer sharing system based on Oracle database

摘要

Yield in a given field may vary in space depending on a combination of factors such as nutrient availability, soil moisture, rooting depth, pest pressure and others. In order to enhance the yield of agricultural production, the maize sharing fertilizer expert system based on oracle database was developed. During designing the system, the author collected clearly some materials for the system and communicated with domain experts about knowledge of maize fertilizer. The sharing system was based B/S. Considering the characteristic of operational research, the author have designed six function modules, which have not been isolated one another, but have integrated to all modules. Every function includes some sub-function modules.
