摘 要:提出了一种新颖的基于Palm OS的PDA(Personal D ig italA ssistan t,个人数字助理)作物施肥通的设计技术,构建了施肥专家系统的知识表,采用了模块化的编程技术,用C语言编写了基于PDA的作物施肥专家系统程序,并将程序固化在PDA存储器中。PDA施肥通内含小麦、玉米、水稻、棉花、油菜和烟草6种大田作物专家系统和一个可扩展的专家系统。它能选择不同的作物、不同的地区,根据土壤中养分的N、P、K或微量元素的含量,建立施肥指导方案,有效地解决了作物种植中科学施肥的问题,使肥料利用率大大提高。通过在农村基层的试验表明:PDA施肥通以其推荐施肥方案合理、体积小、便携性好、价廉和操作简便得到广泛使用。A newly-designed expert fertilizing system based database used for the fertilizing system PDA was designed. on PDA technology was developed and a knowledge By applying a method of modular design, the PDA program was compiled using C programming language for the crop fertilizing expert system and this program was loaded into the PDA memory. This PDA fertilizing expert system consists of six crop subsystems and one extending subsystem, namely, wheat, maize, rice, cotton, cole, tobacco. Because the expert system PDA can distinguish different crops and areas located for planting, and offer the scheme of fertilizing recommendation after obtaining the nutrient contents of N,P,K and trace elements in soil sample, which has solved the problem that farmer cannot scientifically and rationally fertilize for a long time. The efficiency of fertilizer has been improved greatly using the expert system PDA. The crop fertilizing system PDA was verified, validated, and tested in the field, which may be widely used in the countryside of China by its small size, portable, cost-effective, light weight and easy operation.
