Effects of Different Organic and Inorganic Fertilizers on Yield and Quality of Flue-cured Tobacco Variety NC297
In order to effectively solved the problem that the application amount of organic fertilizer is decreasing in tobacco produc-tion,and the improvement of tobacco yield and quality was limited by the combined application of different organic fertilizers and in-organic fertilizers in flue-cured tobacco varieties NC297,and tobacco leaves could not meet the needs of cigarette technology.The ef-fects of four different organic and inorganic fertilizers on the yield and quality of flue-cured tobacco varieties NC297 in Chuxiong to-bacco-growing area were studied.The results showed that the treatment of 30%organic fertilizer+70%inorganic fertilizer was better than other treatments,which could promote the growth and development of flue-cured tobacco and help the upper leaves to open.The yield,output value,average price and proportion of superior tobacco were the highest,which were 2785.3 kg·hm-2,76038.7 yuan·hm-2,27.5 yuan·kg-1 and 69.6%respectively,which could improve the internal chemical composition and quality of tobacco leaves,with a comprehensive score of 83.73 points and remarkable economic benefits.This study provided a theoretical basis for the application and popularization of flue-cured tobacco varieties NC297 with different organic and inorganic fertilizers in Chuxiong to-bacco-growing areas.
