| Curcuma wengyujin Y.H.Chen et C.Ling is a medicinal herb with higher economic value. The components of the oil distilled from the rootstalks of C.Wenyujin have anticancer drugs, such as β-elemene . It is practical significances that fertilization and high yield matched with backgrounds of soil and demands of elementary nutrition are explored during the growth of C.Wenyujin. The circumstances of C.Wenyujin growth on lime stone soil from pure limestone and red soil from sandstone and salt were studied by parallel plant experimentation. The biomass had been measured by reap method of individual plant. The total organic carbon and ionic carbon had been measured by TOC instrument. The concentration of nutrient elements in above-ground parts and below-ground parts of C.Wenyujin and in rhizospheric soil were identified by Inductively Coupled Plasma method (ICP). The low-molecular organic acids had been identified by Anion Spectrum method (AC). The content of the oil distilled from the rootstalks of C.wengyujin had been measured by extracting experiments. The valid components of the oil were identified by Gas Chromatogram-Mass Spectrum method (GC-MS). The results showed that C.Wenyujin has longer growth time on lime soil, in comparison with red soil, the biomass of C.Wenyujin on lime soil reaches the maximum in Nov., while in Oct. on red soil, the biomass of C.Wenyujin and the biomass of the rootstalks used for medicine were larger on lime soil, the biomass of rootstalks on lime soil was 10102.85kg·hm-2 in Nov., while 7402.85kg·hm-2 on red soil in Oct. The content of ionic carbon increased largely in experimental group under the covering of vegetation, comparing to the blank group. During harvest period, supposing the aboveground parts had been returned the soil, the element assimilation gross of N, P, K (unit as kg·hm-2, the same below) and their cycling coefficients in C.Wenyujin were separately 314.16,17.93,138.22,0.28,0.29,0.29 on lime soil while 360.80,27.31,205.81,0.37,0.27,0.48 on red soil. At the same time, the element assimilation gross of Ca,Mg,Fe,Mn,Zn,Cu,Ge,Se and their cycling coefficients were separately 278,43.3,12.2,7.51,0.524,0.063,0.015,0.071,0.943,0.611,0.826,0.269,0.479,0.438,0.487,0.527 on lime soil while 67.9,13.8,5.67,4.24,0.67,0.082,0.011,0.045,0.855,0.532,0.838,0.165,0.200,0.541,0.549,0.418 on red soil. Under planting condition, the losing gross of Ca,Mg,Fe,Mn,Zn,Cu,Ge,Se was separately 345.75,13.04,4.46,4.48,0.177,-0.044,-0.112,0.027 on lime soil while 115.97,6.18,1.62,4.26,0.84,0.146,0.223,0.039 on red soil during growth period. It was analyzed using SPSS software that the relationship between the accumulation gross of Ca, Mg, Fe, Mn, Zn, Cu, Ge, Se, Pb in C.Wenyujin and the available content of Ca,Mg in lime rhizospheric soil was almost negative correlations significant at the 0.05 level but the relationship between the accumulation gross of these elements and the available content of Fe in lime rhizospheric soil was positive correlations significant at the 0.01 level, at the same time, between the available content of Ca, Fe in lime rhizospheric soil had a negative correlation significant at the 0.01 level. In comparison, the negative correlations significant at the 0.05 level only exsisted between the accumulation gross of Mg,Mn in C.Wenyujin and the available content of Ca in red soil rhizospheric soil, only had positive correlations significant at the 0.05 level between the accumulation gross of Ca,Fe,Zn in C.Wenyujin and the available content of Fe in red soil rhizospheric soil either. The close relationship between the content of the low-organic acids in rhizopheric soil and the intensity of nutrition stress to the rootsystem was found.The content of rootstalk's oil of C.Wenyujin planted in lime soil was 5.69% while 4.44% in red soil, the content of β-elemene in the oil was 1.865% in the former while 0.975% in the later. The conclusions are: 1.C.Wenyujin is an anti-infertile economic medicinal herb which can be planted and yielded on lime soil. 2. There is an understanding physiological mechanism using efficiently low content of available Fe in soil. 3. The lime soil has a stronger capacity of resisting negative efforts from fertilization. 4. The vegetation can prevent loss of water and erosion of soil.
