Abstract

The effects of different copper application level on growth,yield and nutrient absorption of flue-cured tobacco was researched.The results showed that copper application level could increase yield,output value and ratio of high grade leaves.The yied,output value and ratio of high grade leaves had significant different with them of CK.When copper application level was 1.35 kg/hm2,the highest yield,output value and proportion of superior grade of leaves could be obtained.The quality was improved with copper application level being 0.45~1.35 kg/hm2.The content of copper in tobacco leaves was improved with copper application level being 0.45 ~0.90 kg/hm2.Comprehensively considering agronomic characters,economic characters,quality and nutrient absorption,the optimum copper application level should be 0.45~0.90 kg/hm2 for high-quality flue-cured tobacco growth in Dianzhong city of Yunnan province.
