Abstract:In order to increase the nitrogen use efficiency,protect ecological environment and increase economic benefits,the test was conducted to find out the optimum nitrogen application rate for flue-cured tobacco in Wenshan region.The effects of different nitrogen fertilizer reducing treatmens on the agronomic traits,disease resistance,economic traits,economic benefits and the inner quality of tobacco leaves were analyzed with Yunyan 87 as material.The results showed that on the basis of conventional fertilization (nitrogen amount as 111 ~ 116 kg/hm2),reducing 10% ~20% of nitrogen was beneficial to the improvement of agronomic traits and disease resistance.When the reduction of nitrogen was 10% and 20%,the comprehensive effects could be improved,the yield increased by 4.5% and 2.2%,and the benefit increased by 28.1% and 24.1%.
