摘　　要：土壤有效养分测定是测土配方施肥工作中最基础和最关键的环节。测定土根据土壤肥力进行合理的品种布局和科学的田间管理是发展高产、优质、高效、低耗、可持续农业的一个必要前提。通过调查得出,保定市土壤有机质含量平均值12.58g/kg,速效磷平均值27.3mg/kg,速效钾平均值135.5mg/kg。对土壤养分现状、肥力水平进行分级,并根据土壤养分含量,提出相应改良措施。Availablenutrienttestingisthemost basicandimportant question insoil testingandfertilizerrecommendation.Distribution and scientific management based on soil fertility is an important prerequisite for high yield, fine quality,high efficiency, low consuming, sustainable agriculture. The result of survey showed that the average orchard soil organic matter content was 15.28g/ kg, rapid available phosphorus and potassium 27.3mg/kg and 135.5 mg/kg respectively. The fertility state was classified and reasonable fertilization was carried out according to soil nutrition state,and accordingto the soil nutrient levels,corresponding improvement measures
