摘　　要：为探究鲁甸乡栽培秦艽传统采收期内不同采收时期秦艽的产量质量差异,确定秦艽最适采收期,作者分析了传统采收期内秦艽鲜重、干重、折干率、长度、直径、体积及龙胆苦苷、马钱苷酸、醇溶性浸出物、总灰分量的变化规律,并采用理想灰关联距离度综合评价法对其产量、外观质量和内在质量进行综合评比。结果表明,传统采收期内二年生和三年生秦艽产量质量均存在较大差异,采收期越晚综合评价越好。由此可知,传统采收期内鲁甸栽培秦艽的采收期越靠后产量越高综合质量越好,生产上可视具体情况适当延后秦艽的采收期。The paper is aimed to study the difference in yield and quality at different harvest time and determine the optimum harvest of planting Gentiana in Ludian traditional harvest period. The authors analyzed the variation in fresh weight,dry weight,dry discount rate,length,diameter,volume and the content of gentiopicroside,loganin acid,alcohol-soluble extract and total ash and made a comprehensive appraisal of yield,appearance quality and intrinsic quality by gray relational distance ideal Comprehensive Evaluation method. The results showed that there is a big difference in yield and quality both 2-year-old and 3-year-old Gentiana harvested in traditional harvest period and the comprehensive evaluation more better when harvested more later. It can be seen,Gentiana harvested the later had a better yield and quality in Ludian traditional harvest period. The harvest of Gentiana can be appropriate delayed depending on the particular circumstances of production.
