Abstract：The orchard soil nutrients in the major pear production regions (Ningling county ,Huangfan tow n farm ,Neihuang county )of Henan province w ere analyzed in 2009 ,so as to provide scientific refer-ence for reasonable fertilizer application of pear orchards .The results showed that the pH value was 7.23-7.37 ,in appropriate level ;the organic matter content was low with 7.3 -11.3 g/kg ;the available nitrogen content was low with 31.42-67.63 mg/kg ;the available phosphorous content was rich with 20.86 -70.23 mg/kg ;available potassium content was 90.84 -201.86 mg/kg ,in appropriate level .The contents of exchangeable Ca and Mg were rich ;the available Mn content was low with 6.17-10.59 mg/kg ;the contents of available Zn and Bn were in appropriate level . In Ningling and Neihuang counties ,the content of available Cu was in appropriate level ,while available Fe was lack .In Huangfan town farm ,the available Cu content was high ,and available Fe was in appropriate level .Overall ,the soil nutrient was different among three regions .Therefore ,it was suggested that some measures should be adopted in the tested pear orchards ,such as increas-ing organic matter ,rational application of nitrogen fertilizer ,sustaining the phosphorus and potas-sium ,increasing the content of Fe ,M n ,and decreasing the Cu fungicide .
