摘　　要：2008年,在云南省通海河西镇水稻土、楚雄子午镇紫色土、寻甸大河桥黄壤土、宜良马街红壤上,研究了不同的氮素形态配比对烤烟的生长发育及产质量的影响。通过对农艺性状、经济性状、化学成分和矿质元素的分析,结果表明:在宜良马街的红壤、楚雄子午镇的紫色土、寻甸大河桥的黄壤上以硝态氮占总氮比例40%～60%左右的处理有利于烤烟品质的提高,在通海河西镇的水稻土上以硝态氮占总氮比例40%左右的处理有利于烤烟品质的提高。Effects of different nitrogen forms on growth, yield and quality of flue-cured tobacco at red soil, purple soil, yellow soil and paddy soil in Yunnan were researched. The result showed that： in the red soil, purple soil and yellow soil, NO3-N accounted for 40%-60% was conducive to the improvement of the quality of flue-cured tobacco; In the paddy soil, NO3-N accounted for 40% was conducive to the improvement of the quality of flue-cured tobacco.
