| Abstract: | A field experiment was carried out to study the effects of combining application of green manure and chemical fertilizer on the growth and development,yield and quality of flue-cured tobacco in dry year.The results showed that the growth of flue-cured tobacco was inhibited in the dry year,especially under no fertilizer applying.Meanwhile the disease of flue-cured tobacco severely occurred,the yield and output value were significantly decreased.In comparison with single chemical fertilizer,combination of green manure and chemical fertilizer significantly increased the plant height,the length and width of the max leaf and stem circumference of flue-cured tobacco,decreased the incidence of granville wilt and tobacco mosaic virus,enhanced the dry weight of root,stem and leaves of flue-cured tobacco.The higher the percentage of green manure accounted for the total rate of fertilizer application,the higher was the yield and output value of the flue-cured tobacco.To compare with single chemical fertilizer application,the yield and output value of flue-cured tobacco that the green manure were applied were 1.16-1.71 times and 1.09-2.16 times,respectively.Combining application of green manure and chemical fertilizer increased the content of nicotine and potassium in all leaves,decreased the ratio of reducing sugar to nicotine in all leaves and the ratio of total nitrogen to nicotine in the middle and lower leaves,and improved the ratio of total nitrogen to nicotine in upper leaves of the flue-cured tobacco.These suggested that the harmony of the chemical component of flue-cured tobacco would be raised when green manure was ploughed in. |
