Experimentation of Curcuma wenyujin in different soil conditions

The effect of different soil conditions on growth of C.wenyujin was studied. Results show that C.wenyujin has longer growth period and higher biomass in lime soil. Naphtha content distilled from rootstalks of C.wenyujin in lime soils is also higher in comparison with those in red soils. Lime soil has a stronger capacity of resisting negative effects owing to NH⁺₄-N fertilizer.
