烟草氮肥运筹知识模型系统的设计与实现

Design and Implementation of a Knowledge Model System for Tobacco Nitrogen Strategies

采用数据库和多媒体技术建立了烟草氮肥运筹知识模型系统,用于确定不同地区和生产条件下的烟草氮肥运筹方案.系统包括数据管理、生长动态、氮肥运筹和生产技术4个部分,可根据烟草发育时期和长势长相为管理者提供烟田氮肥丰缺状况、烟株氮素分布情况等有效信息,同时还具有智能学习,实时掌握根系生长时空分布等功能.

Via the technology of database and multimedia, a Tobacco Nitrogen Strategy Knowledge Model System was developed which contained scenarios of tobacco nitrogen operation in different planting locations under varied conditions. The said system, which is composed of four parts, namely, data management, tobacco growth, nitrogen strategy, and production technology, can offer tobacco planters useful information like nitrogen fertilization situation in field, nitrogen distribution in plant, etc. According to the growth stage, growth appearance, and growth trend of the tobacco plants. Besides, the system is also capable of intelligence learning and synchronic command of tobacco root growth and its time and spatial distribution.
