烤烟品种豫烟10号生长发育及营养元素吸收特性研究
Study on Characteristics of Growth, Development and Nutrient Element Absorption of Flue-cured Tobacco Variety Yuyan 10
摘要
Abstract
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.关键词
