补充资料：烤烟(flue-cured tobacco)
| 烤烟(flue-cured tobacco) 烟草的主要类型。烟叶通过烤房火管加热调制，又称火管烤烟。因源于美国弗吉尼亚州，也称弗吉尼亚烟。是卷烟工业的主要原料。也可作斗烟，是世界上栽培面积最大的烟草类型。主产国有中国、美国、巴西、印度、津巴布韦，其次为加拿大、日本、南朝鲜、泰国。1900年中国台湾省最早引进种植。1910-1916年先后在山东潍县、河南襄城、安徽凤阳等地试种。1937-1941年四川、云南、贵州先后试种。 烤烟叶片在植株上分布比较疏散而均匀，厚薄适中，中部叶品质最好。适宜在结构良好的壤土和沙质壤土上栽培。种植密度为每公顷1.3万-1.6万株，中国为1.9万-2.7万株。栽培过程中要打顶(去顶芽)、抹杈(去腋芽)，不宜施用过多的氮素肥料，根据叶片成熟度分次采收烘烤。烟叶烤后呈金黄色，含糖量较高，蛋白质含量较低，尼古丁含量中等。中国烤烟栽培面积常在53万公顷左右。有22个省(自治区)近900个县、市种植，主产区分布在河南、山东、云南、贵州、湖南、安徽、广西、四川、湖北、福建、广东、陕西、黑龙江、辽宁、吉林等省(自治区)，各地栽培多为春烟，少数为夏烟，冬季温暖的地方有冬烟。 |
