摘　　要：以中国农业科学院禹城试验站轻壤质盐化潮土(黄河冲积平原土壤)20年肥料长期定位试验为平台,系统研究了有机无机肥料长期配施对作物产量及氮素吸收利用的影响。结果表明:在等氮量条件下,长期施用常量无机肥虽然小麦和玉米秸秆的含氮量较高,但向籽粒氮转移量和生理效率却较低;长期施用常量有机肥小麦和玉米生理效率较高,而含氮量和氮转移量却较低;只有常量有机无机肥料配施才能逐步提高小麦和玉米产量、经济系数、含氮量、氮素转移量和生理效率。Based on the 20 - year fertilization experiment in light - loamy salinized fluvo - aquic soil （ alluvial soil by the Yellow River） in Yucheng experiment station of Chinese Academy of Agricultural Sciences, the research systematically studied the effects of long -term combined application of organic and inorganic fertilizers on crop yield and nitrogen uptake. The results were as follows. At the same amount of nitrogen, in the treatment of long - term fertilization of normal inorganic fertilizer, the nitrogen content in wheat and maize stalk was higher, but the nitrogen quantity transported to grain and its physiological efficiency was lower. In the treatment of long - term fertilization of organic manure, the nitrogen physiological efficiency in wheat and maize was higher, while the nitrogen content and nitrogen transfer ammount were lower. Only long - term combined application of organic and inorganic fertilizers had increased the grain yields, economic coefficient, nitrogen contents, nitrogen transter ammount and its physiological efficiency.
