Soil Investigation of Curcuma aromatica Salisb.in Guangxi

Objective To investigate the soil distribution of C.aromatica in Guangxi and to provide evidence for the conservation and artificial cultivation.Methods Field investigation and laboratory test are used to investigate the to pographical features,soil types,soil thickness,pH,organic matter content and mineral content in the distribution area of C.aromatica in Guangxi.Results Wild C.aromatica has strong adaptability,it is distributed in limestone mountains,earthen hills and plains,and is usually born at the foot of mountains,gully edge,field edge and roadside.It has a wide range of adaptability to soil types,soil depth,pH and soil fertility,and can be distributed in sandy loam,loam and clay loam.Loam is the main soil,which has low requirements on soil fertility and is relatively resistant to poor soil,heavy metals in soil exceed the standard in some areas.Conclusion Most of the sample plots in this survey meet the requirements of soil environmental quality for the cultivation of green medicinal materials and are suitable for the construction of GAP base.
