摘要
在分析了影响烟叶施肥的因素及相互作用关系和收集完整的技术参数的基础上，运用农业系统工程分析的原理和方法，总结与汇集烟草专家的施肥经验，建立数学模型。依靠各种基础资料数据库，研究出“烤烟配方施肥专家系统”。３ａ的应用结果表明，配方施肥的上等烟比对照提高２０．６７％；烟叶产量提高２７．３３％；烟叶产值、净收入分别比对照增加３３．７％和１０８％，而生产费用仅增加１２．７％。
On the basis of experiment in the field and according to the knowledge of agreculturists,an expert system of balance fertilizer in flue cured tobacco was set up by using the theory and method of systematic analysis.Three yearsapplication results indecated that the superior leaf ,yield of leaf,output value and net income of the balance fertilizer had increased by 20.67%,30.10%,83.7% and 108% respectively, compared to those of the control while production cost only increased by 12.7%.
