Investigation of soil environmental quality conditions in dioscorea opposita thunb arae

Abstract:An approach of combining with field investigation and indoor analysis was introduced to study the geography, climate, hydrogeology, composition of nutrition in the soil and heavy metal element in the producing area of diaoscorea opposita thumb.The results indicated that the climatic conditions of rain and hot simultaneously, the fertile soil of wash plain's as basic material, the soil texture in well irrigation and drainage condition, the heavy metal of right amount and non-pollution's soil environment, which provide an excellent condition to the development of diaoscorea opposita thumb for medicinal purposes, and also provides the science basis for the Wenxian diaoscorea opposita thumb planting.
