摘要：

研究在分析了植物营养元素知识及典型症状内在规律的基础上，以文献知识为主要获取方法。在研究过程中，收集了覆盖常见作物的元素丰缺条件下的典型与非典型症状描述，直接进入数据库的有286条。以此为基础，提出了作物营养元素症状描述的客观标准集：（1）按元素分类建立了12种元素的客观标准集；（2）在对客观标准集分析归纳的基础上，建立了植株的表观症状描述、部位的表观症状描述、叶片的表观症状描述和诊断检索表；（3）分析了以SQL server2000为数据库平台的技术优势。本知识库的建立为诊断系统成功开发奠定了知识基础。

Abstract:

Objective criterions describing plant symptoms responding to nutrient sufficiency and deficiency have been established based on extensive literature review. Typical and non-typical symptoms of most crops, which were in a total number of 286, had been input to the database. These symptoms were classified according to elements, and an objective criterion was established for each of the 12 elements. An index describing the apparent symptoms regarding the plants, locations and leaves was also established for diagnosing search. This paper finally discussed the advantages of using SQL server2000 as the database platform. This study could contribute to the development of plant nutrition diagnose databases.
