在分析、整理国内外甘蔗施肥经验、研究成果的基础上，运用专家系统的理论方法，设计出甘蔗施肥专家系统，指导农民合理施肥，系统能在多个专家水平级上进行施肥决策。由于我国种蔗面积分布广阔，土壤、气候、品种及耕种水平等差异大，在甘蔗合理施肥方面存在严重不规范问题，甘蔗施肥成果难于应用于生产实际。该项研究在解决这些问题的技术方面有较大突破。 Based on the analysis and finishing of experience and research results of sugarcane fertilization both at home and abroad, the expert system was used to design an expert system of sugarcane fertilization to guide farmers to apply fertilizers reasonably. The system can make fertilization decisions at the level of several experts. Due to the vast area of ​​sugarcane in China, there are big differences in soil, climate, variety and cultivation level. There are serious non-standard problems in sugarcane reasonable fertilization, and the results of sugarcane fertilization are hard to apply to the actual production. The study made a big breakthrough in the technical aspects of solving these problems.
