Abstract
To find out the effect of organic manure on growth,development and quality of flue-cured tobacco,experiment on effect of different nitrogen rates and application of organic manure on yield and quality of tobacco leaf was conducted in Yunxi in 2002.The results showed that yield and output value of flue-cured tobacco were increased with the increment of nitrogen rate,while the difference between 90 kg/hm2 and 135 kg/hm2 was not significant.Application of organic manure affected yield and output value,and they were increased 26.76% and 29.33% respectively,while it had no evident effect on appearance quality of tobacco leaves(fine tobacco ratio).Nitrogen application rate affected characteristics of tobacco leaf,the leaf showed small,weak color and bad maturity when nitrogen rate was lower than 67.5 kg/hm2,while the leaf showed big,deep color amd good maturity when nitrogen rate was beyond 67.5 kg/hm2.Analysis of variance showed that interaction between nitrogen rate and organic manure application was not existed.At the base of some nitrogen application rate,application of stable manure 7 500 kg/hm2 and cake fertilizer 225 kg/hm2 could improve the growth,yield and quality of flue-cured tobacco.
