Aimed at dealing with the serious problems brought about by irrational fertilization which detered the growth
yield and quality of flue-cured tobacco in Loess Plateau of east Gansu province
the present research had probed into the effects of different nitrogen fertilizers(ANP and UA) on yield formation of the flue-cured tobacco and its mechanisms
in 2009 in Zhengning county
Gansu.The results showed that:ANP significantly promoted the growth of roots and enhanced the activities of roots.Compared with UA trea...
