摘要
根据实际生产中普遍存在着肥料用量过多或过少,各种肥料配比不合适等问题,以小麦施肥决策系统领域专家的知识和经验为基础,有助于上述问题的解决。详细论述了如何使用专家系统和知识库技术实现小麦施肥决策知识库和推理机,并对用户所提交数据的有效性验证进行了分析讨论。系统可根据用户提供的基本数据进行土壤缺素和施肥量的决策。该知识库已经集成到山西省小麦专家系统中,经过示范区的生产实践已取得了成效。
There are many problems in wheat production such as too many or too few of fertilizing amounts, improper proportion of kinds of fertilizers and so on. Wheat expert system of fertilization decision-making is based on knowledge and experience of wheat experts and can help farmers to solving above problems. This paper describes and discusses how to build knowledge base of wheat fertilization decision-making and reasoning mechanism by expert system and knowledge base. Also, testing and verifying validity of data submitted by the users are discussed. The system can make decisions about amount of fertilizing and elements in soil depending on data submitted by the users. Knowledge base of wheat fertilization decision-making has been integrated into wheat expert system in Shanxi province. After running in the demonstration districts, the system has achieved good result.
