| Abstract: | Field investigation and laboratory analysis were made on different aspects of the soils for growth of dioscorea opposita thunb, suth as distribution, types, physical and chemical properties, etc. Different soil type and different physical and chemical properties caused different quality of diaoscorea opposita thunb. Cinnamonazation mixed soil is the most fitting soil species. among sand loam soil ,small mixed soil, miry soil and cinnamonazation mixed soil for the growth of dioscorea opposita thunb, which is perfect in the aspects of soil texture ,soil structure, sand-clay proportion, soil tilth and soil nutrition, so the output and quality of dioscorea opposita thunb,is best. |
