Abstract:: Through the investigation and analysis, the soil and plant analyzer development (SPAD) values of winter wheat leaves and mineral nitrogen contents of Lou soil under the long-term fertilization were characterized. The results showed that:(1) the changes of nitrate nitrogen and ammonium nitrogen contents in different soil layers were not consistent during the winter wheat grwoth period. The contents of nitrate nitrogen were decreased first and then increased, while the content of ammonium nitrogen has been rising, the contents of nitrate nitrogen and ammonium nitrogen of treatment with no nitrogen fertilizer were significantly lower than those of treatments with nitrogen fertilizer in the different soil layers (0-20 cm, 20-40 cm); (2) during the growth period of winter wheat, the SPAD values of all treatments were different, but all of which first increased and then decreased. The SPAD values of leaves under the treatment with no nitrogen fertilizer were lower than those of the treatments with nitrogen fertilizer application; (3) during winter wheat growth period, SPAD values of leaves and nitrate nitrogen contents were significantly positively correlated in different soil layers (0-20 cm, 20-40 cm), while their correlation with the content of ammonium nitrogen was not significant, indicating that wheat is sensitive to nitrate nitrogen to some extent. The results could provide the reference for manipulation of the nitrogen fertilizer application and understanding the effect of nitrogen fertilization on the yield and quality of winter wheat.
