以中烟100、NC297为对照品种，研究了烤烟品种豫烟10号在大田的生长发育及营养元素吸收特性。结果表明：在移栽后30～45 d，豫烟10号的光合特性好，长势快，干物质积累量及营养元素吸收量均高于2个对照品种的；在移栽后45～60 d，豫烟10号的干物质积累速率降低，营养元素吸收量较对照品种少；在移栽后60～90 d，豫烟10号的净光合速率显著低于NC297的，且烟株叶片表现为易成熟落黄。

Taking Zhongyan 100 and NC297 as the control varieties, the author studied the characteristics of growth, develop-ment and nutrient element absorption of flue-cured tobacco variety Yuyan 10 in the field.The results indicated that:from the 30th day to the 45th day after transplanting, Yuyan 10 had good photosynthetic characteristics and rapid growth speed, and its dry matter accumulation and nutrient element absorption were all higher than those of two control varieties;from the 45th day to the 60th day after transplanting, the rate of dry matter accumulation in Yuyan 10 decreased, and its nutrient element absorption was less than that of control varieties; during 60~90 d after transplanting, Yuyan 10 possessed a significantly lower net photosynthetic rate than NC297, and the leaves of its plants easily yellowed and matured.
