Effects of Different Organic Fertilizer Application on Growth and Development of Flue-cured Tobacco K326 and Inorganic Nitrogen in Soil

The effects of different kinds of fertilizer application on the agronomic characters,appearance quality of tobacco leaves,and economic traits of flue-cured tobacco K326 were studied in this paper.The results showed that the proper application of organic fertilizer could promote the growth of tobacco leaves,improve the agronomic characters of tobacco plants,and gain better economic benefit.Comprehensively considering the experimental results,the tobacco plants treated with cake fertilizer revealed better agronomic characters;applying chicken manure could improve the appearance quality of flue-cured tobacco leaves,and acquire better economic benefit;the tobacco plants treated by pure chemical fertilizer application matured earlier,but they had the worst performance in agronomic characters and so on.
