In this paper,researches on abundancedeficiency index(ADI)of soil available P for potato(SAPFP)and appropriate phosphorus fertilizer application rate(APFAR)conducted in China since the 1980s were systematically summarized.The results showed that the ADI of SAPFP in China had appeared rising trend in 30 years,and APFAR had a down trend at the same time.There were considerable differences in their ADI of SAPFP in different regions,and the ADI of soil available P(OlsenP)for potato for 90% relative yield(RY)of the complete nutrients treatment except phosphorus(TCNTEP)changed from 13 to 55 mg/kg.Except Inner Mongolia,Fujian and Chongqing,researches on ADI of SAPFP in China had many blank regions.Soil available P deficiency for potato in China were common,and the abundancedeficiency levels of SAPFP focused on level 2～4,and most RYs of TCNTEP were between 70%～100%.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.The APFAR for different abundancedeficiency levels of SAPFP could be determined with methods of nutrient balance and dissimilar subtraction of soil fertility.APFAR and the abundancedeficiency level of SAPFP were linear negative correlation.APFAR and the yield goal were linear positive correlation.APFAR and the phosphorus fertilizer use efficiency in current season(PFUEICS)were linear negative correlation.When the PFUEICS of 20% and the target yield of 15～60 t/hm2,the APFAR for the SAPFP abundancedeficiency level 1～7 from high to low were 0～0,12～48,24～96,36～144,48～192,60～240 and 72～288 kg/hm2,respectively.
