Abstract
【Objective】 In view of the decrease in tobacco quality and soil fertility in continunous cropping tobacco field,we studied the effect of fertilization on soil and tobacoo qualities,and selected the optimum fertilization model to provide evidence for flue-cured tobacco production in Weibei dryland of Shaanxi province.【Method】 With Qinyan96 as the tobacco species tested in Longxian Shaanxi province in 2008,and no fertilizer as control treatment,the agronomical character and the quality of tobacco,soil physic-chemical properties of different fertilizing steps(chemical fertilizer,tobacco-specific fertilizer,organic manure,organic manure and chemical fertilizer) were analyzed,meanwhile the data were finished by the correlation and differential analysis.【Result】 The agronomical character of tobacco,soil fertility and quality of tobacco after applying organic manure+chemical fertilizer was improved.The organic matter increased to 38.3%,the quality of tobacco was improved because the tobacco height,leaf numbers,stem girth,knot length,maximum leaf length and maximum leaf width were increased.There were significant or remarkably significant positive correlations between organic,alkali N,available P of soils and agronomical characters of tobaccos,and the same to the available K in soil and nicotine,nitrogen and potassi in tobacco.【Conclusion】 Soil fertility and tobacco quality were synchronized after appling fertilizers,and organic manure + chemical fertilizer is a better fertilizing model in Shaanxi Province.Soil available K is one of the major ways to improve tobacco quality.
