The study was set up at the demonstration site of Pyrus Bretschneideri Rehd(“Korla Pear”)with relatively higher integrated management level to describe the relationship between the main nutrient elements in the soil of Korla Pear and its yield by measuring the contents of main nutrient elements in the soil and the yield for Korla Pear.The results were as follows:（1）The content of organic matter and available phosphorus in the 0～20 cm soil was higher than that in the 20～60 cm soil,while the content of alkalihydrolyzable nitrogen and available potassium in the 0～20 cm soil was lower than that in the 20～60 cm soil.（2）The correlation between the content of organic matter in the 0～20 cm soil and the yield of Korla Pear could be represented by a logarithmic function（P=0.021）.The correlation between the content of organic matter in the 20～60 cm soil and the yield of Korla Pear could be represented by a power function（P=0.034）.The correlation between the content of alkalihydrolyzable nitrogen in the 0～20 cm soil and the yield of Korla Pear was not significant,and could be represented by a power function.The correlation between the content of alkalihydrolyzable nitrogen in the 20～60 cm soil and the yield of Korla Pear could be represented by a logarithmic function（P=0.053）.The content of available phosphorus in both the 0～20 cm soil and the 20～60 cm soil had a significant logarithmic correlation with the yield(P=0.014，0.002).The content of available potassium in the 0~20 cm soil had a significant power correlation with the yield of Korla Pear(P=0041).As a whole,the content of organic matter,alkalihydrolyzable nitrogen,available phosphorus and available potassium in the 20～60 cm soil was significantly correlated with the yield of Korla Pear.Thus,the fertilizer should be applied in deeper soil layers,iethe depth of fertilization was ≥20 cm; the relational model of the soil nutrients(x)and the yield(y)was established.Specifically,for organic matter y=28.56x0.22,for alkali hydrolyzable nitrogen y=16.02lnx+91.72,for available phosphorus y=16.42lnx+110.11,for and available potassium y=75.96x0.28.The goal of recommending specific amount of fertilizer based on target yield of Korla Pear was achieved.
