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

Objective: 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.
