Effects of Different Cultivation Forms on Growth and Quality of Tibet Medicine Gentiana straminea Maxim

To study the influence of 5 cultivation forms on yield and quality of Gentiana straminea Maxim including the white membrane cover side-gutter plants,the black membrane cover side-gutter plants,the white membrane cover horizontal plants,the black membrane cover horizontal plants and the open field horizontal plants in Gannan plateau area,a field experiment was designed by single factor and randomized block.The results showed that as for the black membrane cover side-gutter plants,the yield and the quality were the highest;its yield was 10775.00kg/ha,which was increased 85.38% than that for the open field horizontal plants.Also,the content of loganic acid,geatiopicroside and loganic acid of the black membrane cover side-gutter plants were also the highest(2.76%、4.15% and 0.197%),which were increased significantly by 0.39,0.47 and 0.33 percentage points than CK,respectively.In short,the black membrane cover side-gutter was the best membrane tutorial production cultivation forms of Gentiana straminea Maxime,and it was vigorously applied in production.
