移栽期及移栽方法对秦艽产、质量的影响初探

The Effection Study of Transplanting Techniques for Yield and Quality of Gentiana crassicaulis

目的:为探究鲁甸乡栽培秦艽传统移栽期内及不同移栽方法秦艽的产、质量差异,确定秦艽最适移栽期及移栽方法。方法:分析测定了秦艽鲜重、干重、折干率、长度、直径、分支数及龙胆苦苷、马钱苷酸、醇溶性浸出物、总灰分含量,采用理想灰关联距离度综合评价法对其产、质量进行评价。结果:不同移栽期和移栽方法秦艽产、质量均存在较大差异,在3月10日以行株距25 cm×24 cm、覆土1 cm平放移栽的秦艽产、质量最好。结论:综合考虑产、质量及操作性,鲁甸乡秦艽生产应在3月上旬末,在传统移栽方法的基础上减少覆土厚度进行移栽较适宜。

Obejective： To study the difference in yield and quality of Gentiana crassicaulis with different transplanting period and transplanting methods,and to determine the optimum transplanting technique of Gentiana crassicaulis in Ludian. Methods： The variation in fresh weight,dry weight,dry discount rate,length,diameter,branches,the content of gentiopicroside,loganin acid,alcohol-soluble extract,total ash were measured,and made a comprehensive evaluation of yield and quality by gray relational distance ideal comprehensive evaluation method. Results： There was a big difference in yield and quality of Gentiana crassicaulis with different transplanting time and transplanting methods. Gentiana crassicaulis were transplanted in March 10 with the density of 25 cm × 24 cm,and overburden 1 cm and flat transplanting had the best comprehensive evaluation of yield and quality. Conclusion： The transplanting time of Gentiana crassicaulis in Ludian should begin at the end of early March,and reduce overburden soil on the traditional transplanting methods.
