摘　　要：通过对邵阳县金称市镇和塘田镇2个土地整理项目区植烟土壤样品采集,分析耕作层土壤有效钙、镁、硫含量,探讨邵阳县烟稻轮作区土地整理后烟田土壤钙、镁、硫含量状况。结果表明,项目区土壤交换性钙和有效硫含量较丰富,交换性镁含量偏低;成土母质对交换性钙含量影响较大,对交换性镁和有效硫含量影响较小;土地整理导致耕作层土壤交换性钙含量下降,交换性镁含量有所提高,有效硫含量趋于丰富。因此,在项目区烤烟生产中应重视增加镁肥的施用,适当补充钙肥和硫肥。By collecting tobacco-growing soil samples and analyzing available Calcium, magnesium and sulfur contents from two land consolidation projects in Jincheng Town and Tangtian Town, analyzed the content of available calcium, magnesium and sulfur, discussed the contents of calcium, magnesium and sulfur in tobacco field soil after land consolidation in tobacco rice rotation area in Shaoyang County. The results showed that the exchangeable calcium and available sulfur content in the project area were rich and the exchangeable magnesium content was low; soil parent material had great influence on the content of exchangeable calcium, and has little effect on exchangeable magnesium and of effective sulfur content; land consolidation resulted in a decrease in soil exchangeable calcium content,the exchangeable magnesium content increased and the effective sulfur content tended to rich.Therefore, in the project area during the tobacco production should pay attention to increase the application of magnesium, and add calcium and sulfur fertilizer appropriately.
