摘　　要：对淋溶褐土、石灰性褐土、潮土、砂姜黑土、黄褐土５种土壤中的中、微量元素含量进行了测定。结果表明，不同土壤对烟株营养元素的供应特点是黄褐土、砂姜黑土较好，除缺有效铜、锌外，土壤中有效镁、硫、铁、锰的含量中等，钙含量较低。淋溶褐土的供肥性能最差，土壤ｐＨ值偏高，钙及其他营养元素的含量都与优质烤烟生长所需条件相差较大，土壤中微量元素铁、锰、铜、锌均在土壤临界值之下。石灰性褐土、潮土的供肥性能介于两者之间。The determination of the contents of mid and micro nutrients in Calcic Cambisol Soil,Calcaric Gleysols,Ortyic Lurisols,Eutric Cambisols,Chromic Cambisols showed that, Chromic Cambisols,Calcaric Gleysols are the best to supply nutrients for tobacco with favorable pH,lower calcium and moderate available magnesium,sulfur,iron and manganese,except for being short of available copper and zinc. Orthic Lurisol is not favorable for the tobacco growth with higher pH,higher content of calcium and lower iron,manganese,copper and zinc content. The supplying property of nutrient of Eutric Cambisols,Calcic Cambisol soil are just between the two soils mentioned above.
