摘要
通过对广西隆安县甘蔗产区不同地层甘蔗生长状况和产量的调查，划分甘蔗生长的适宜地层，并通过母岩、土壤、甘蔗植株中３１种元素含量的分析，研究植物与地球化学环境之间的关系，确定对甘蔗生产产生影响的元素。结果是：不同地层上甘蔗产量差异显著，以Ｃ３为优势区，Ｃ２、Ｄ２ｄ２为次优势区，Ｄ３、ＱＰ为劣势区，对甘蔗生产有明显促进作用的营养元素有Ｋ、Ｎａ、Ｂ、Ｎ；对甘蔗产量的提高有抑制影响的元素有Ａｓ、Ｃｒ、Ｃｕ、Ｃａ。
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.
