Abstract
In order to explore the effects of water-nitrogen coupling on dry matter and nutrient accumulation of flue-cured tobacco, 9 treatments with different lowest limits and nitrogen fertilizer amount were designed, and the distribution and accumulation of dry matter and nutrient (N, P and K) of flue-cured tobaccos under water-nitrogen coupling treatments were observed. Results showed that: (1) High irrigation amount could not certainly increase the dry matter accumulation of tobacco root, but which was beneficial to the dry matter accumulation of whole tobacco plant. (2) Dry weight proportion of flue-cured tobacco leaves was highest, which was above 55% among the treatments. (3) Higher water and nitrogen promoted the nutrient accumulation of flue-cured tobaccos, nutrient content of W3N3, W3N2 and W2N2 was higher compared to other treatments.
