Abstract: In this paper,research on abundance-deficiency index（ADI） of soil N for wheat（SNFW） and appropriate nitrogen fertilizer application rate （ANFAR） conducted in China were systematically summarized. The results showed that the ADI of SNFW in China had not changed obviously in 30 years. There were considerable differences in their ADI of SNFW in different regions,and the ADI of soil alkaline hydrolysis nitrogen for wheat for 60% relative yield （RY） of the complete nutrients treatment except nitrogen （TCNTEN） changed from 21 to 97 mg/kg. Except the Guanzhong irrigation district,Hetao irrigation area and the Hexi corridor,research on ADI of SNFW in China had many blank regions. Soil N deficiency for wheat in China were common, and the abundance-deficiency levels of SNFW focused on level 4~5,and most RYs of TCNTEN were between 60%~80%. For research on ADI of soil nutrient,the number of trial sites should not be too little,and using extrapolating data for the high-end and low-end of ADI should be careful and indicated. ANFAR and the abundance- deficiency level of SNFW are linear negative correlation. ANFAR and the yield goal of wheat are linear positive correlation. ANFAR and the nitrogen fertilizer use efficiency in current season （NFUEICS） are linear negative correlation. When the NFUEICS of 40% and the target yield of 3~12 t/hm^2,the ANFAR for the SNFW abundance-deficiency level 1~7 from high to low are 0~0, 21 ~84,42~168,63~252,84~336,105~420 and 126~504 kg/hm^2, respectively.
