Abstract: Based on investigation on growth and yield of Saccharum sinense plantations in different geospheres in Longan county, Guangxi province, the plantable geosphere was recognized. Through sampling test for contents of 31 elements in rocks、 soils and plants in the different geosphere, the relationship between the plant and environmental geochemistry was studied and the major elements affecting growth of S. sinense were determined. The results indicate that geosphere type differed greatly in the yield of S. sonense. C3 geosphere was good region, D3 and Qp geosphere were bad region and C2 and D2d2 geosphere were intermediate. S. sinense yield could be increased with applying K, Na, B and N while decreased with the application of As, Cr, Cu and Ca.
