Different letters within a column imply significant differences between different treatments at P< 0.05. CK: traditional irrigation and fertilization methods; I1: surface drip fertilization; I2: underground drip fertilization; YN: grain yield in N -applying plot; YNN: grain yield in non-nitrogen-applying plot.
