Abstract: In this paper, researches on abundance- deficiency index (ADI) of soil N for rice (SNFR) and appropriate nitrogen fertilizer application rates (ANFAR) conducted in China are systematically summarized. The results show that there are considerable differences of ADI of SNFR in different regions, soil alkaline hydrolysis nitrogen is 131- 248 mg/kg of 90% relative yield of no nitrogen fertilizer treatment. Except 4 provinces of Liaoning, Fujian, Guangdong and Yunnan, researches on ADI of SNFR in China have many blank areas. Soil N deficiency for rice in China is common, and the abundance-deficiency levels of SNFR focus on level 3-5, and the relative yield of no nitrogen fertilizer treatment is between 60%-90%. For research on ADI of soil nutrient, the number of trial sites should not be too limited，and using extrapolating data for the highend and low-end of ADI should be careful and clearly indicated. ANFAR and the abundance-deficiency level of SNFR have a linear negative correlation, ANFAR and the goal yield of rice have a linear positive correlation, and ANFAR and the nitrogen fertilizer use efficiency in current season (NFUEICS) have a linear negative correlation. When the NFUEICS is 40% and the target yield is 4.5- 15 t/hm2, the ANFAR for the SNFR abundance-deficiency level 1-7 from high to low is 0-0, 23-75, 45-150, 68-225, 90-300, 113-375 and 135- 450 kg/hm2, respectively.
