#$%^&*AU2020101690A420200910.pdf#####ABSTRACT The present invention relates to a method for nitrogen application via drip irrigation for improving nitrogen use efficiency (NUE) of flue-cured tobacco. In the method, nitrogen application via drip irrigation is combined with split nitrogen application to decrease a proportion of base fertilizer nitrogen, increase a proportion of top-dressed fertilizer nitrogen, and supply nutrients in accordance with nitrogen requirements of flue-cured tobacco, achieving integration of water and fertilizer and a reduction of the loss of nitrogen fertilizer. The NUE in this present invention is increased by more than 20% compared with that in the conventional technology.DRAWINGS 60 - a 50 -b b EOTi bcE 0T2 40d dd de 0T e *TT 30 20 *T6 *T7 10 UT8 *T9 TI T2 T3 T4 T5 T6 T7 T8 T9 Treatment FIG. 1 15
