Yield

quality

and water use efficiency(WUE)of Gentiana straminea Maxim were compared in five cultivation modes including white film covered row side planting

black film covered row side planting

white film covered flat planting

black film covered flat planting

bare surface planting in Gannan Plateau

with single factor randomized block design.The results show than black film covered row side planting achieved the highest yield

the most superior quality

and the highest WUE.Specifically

the yield and the WUE of economic yield and biological yield were 39.52%

59.53%

and 21.16% higher than the control

respectively.In short

the black film covered row side planting was the best production cultivation mode of Gentiana straminea Maxim

and should be promoted to a greater extent
