Effects of Different Organic Fertilizers on Tobacco Quality

[Objective] The aim was to select a low price and high quality organic fertilizer.[Method]The impact of different types of organic fertilizer on the yield and quality of tobacco was analyzed.[Result] The results showed that:Using the organic fertilizer of Zhongyan,the tobacco plants in field grown fastest.Meanwhile,the seedlings performed significantly in early growth and fast sprout,strong resistance to virus disease(TMV,CMV and PVY),good-open leaves,the highest proportion of superior tobacco,higher production,value and average price,better coordination of the chemical composition and high score of the sensory evaluation of the upper leaves.Using the organic fertilizer of Bafuxian(7-5-13) and under with more nitrogen application than other treatments,the tobacco plants in field grown well and also performed a strong resistance to virus disease(TMV,CMV and PVY).Simultaneously,there had good-open leaves,the production,value and average price being in the first place and the proportion of superior tobacco being the third.After being flue-cured,the oily of tobacco leaves increased,and owing the good coordination of the chemical composition and high score of the sensory evaluation of the lower leaves.Its comprehensive representation was well.Using the fertilizer of Hongwang,there had a certain improvement for the quality of leaves in all three parts of tobacco,although the agronomic traits,economic traits and the appearance of tobacco leaves were poorer than using the organic fertilizer of Zhongyan and Bafuxian(7-15-13).[Conclusion] The results provided a scientific reference for tobacco production.
