摘要
目的对广西毛郁金分布区的土壤进行调查,为广西毛郁金资源保护和人工种植提供依据。方法采用实地调查和实验室检验相结合的方法,调查广西毛郁金分布区的地理地貌、土壤类型、土层厚度、pH值、有机质含量以及各种矿物质含量。结果野生毛郁金适应性强,在石灰岩山区、土山丘陵和平原均有分布,通常生于山脚下、溪沟边、田边和路边,对土壤类型、土层深度、pH值和土壤肥力的适应范围较广,能分布于砂壤土、壤土、黏壤土中,以壤土为主,对土壤肥力要求不高,比较耐贫瘠土壤,部分地区毛郁金土壤重金属超标。结论调查的样地大部分都符合绿色药材栽培的土壤环境质量要求,适合建设GAP基地。
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.
