Interaction Effects of Planting Density and Organic Nitrogen Rate on Yield and Quality of Flue-cured Tobacco in Changsha
摘要
Abstract
In order to find out the optimum planting density and organic nitrogen level for flue-cured tobacco growing in Changsha area,the effects of density and organic nitrogen levels on the yield and quality of flue-cured tobacco were studied.Results showed that the plant height was 116.20 cm at treatment of low density and low organic nitrogen,which was the highest.The largest leaf area was 1633.30 cm2 at the treatment of the highest density and low organic nitrogen,which was the maximum.The leaf number at treatment of low density and medium organic nitrogen was 4.65 leaves,which was the most.The nicotine content of tobacco leaves was significantly reduced by increasing density.The chemical components of tobacco leaves were the best at treatment of low density and medium organic nitrogen.Under the conditions of this experiment,the comprehensive economic benefit was the best at treatment of low density and high organic nitrogen,and the yield and output value were the highest,which reached 2225.1 kg/hm2 and 42 844.5 Yuan/hm2,respectively.关键词
