Effects of application of gramineous straw on yield,production value and quality of flue-cured tobacco

Experiments were carried out in four kinds of red soils to evaluate the effects of application of suitable and high quantity of mineral fertilizer, wheat straw, maize straw, organic soil amendment and rape cake with the mineral fertilizer on the yield, output value and quality of flue-cured tobacco during three years. The results showed that the output value and score of smoking quality of tobacco were significantly increased,the influence on yield and chemical quality of tobacco could not be observed obviously for application of wheat straw(7500 kg/ hm~2 in paddy field,6000 kg/ hm~2 in arid land) before transplanting the tobacco.As a result,flue-cured tobacco with high quality and appropriate yield will be obtained by use of gramineous straw with mineral fertilizer.
