摘　　要：为了解新疆石榴主产区土壤养分状况,采用室内分析测定,对石榴果园不同树龄的0~20cm、20~40cm范围内石榴园土壤有机质、全氮、速效氮、速效磷、速效钾含量进行了测定分析。结果表明:石榴园不同树龄、不同土层深度的土壤有机质含量范围分别为0.576 0~0.659 5g·kg^(-1)、0.402 5~0.504 0g·kg^(-1),平均值分别为0.617 8、0.453 3g·kg^(-1);土壤全氮含量变化范围分别为0.069 5~0.072 5mg·kg^(-1)、0.058 5~0.060 5mg·kg^(-1),平均值分别为0.071 0、0.059 5mg·kg^(-1);土壤速效氮含量变化范围分别为54.079 0~63.106 0mg·kg~(^(-1))、52.091 0~57.153 5mg·kg^(-1),平均值分别为58.592 5、54.622 3mg·kg^(-1);土壤速效磷含量变化范围为32.362 5~36.704 0mg·kg^(-1)、19.683 5~22.042 5mg·kg^(-1),平均值分别为34.533 3、20.863 0mg·kg^(-1);土壤速效钾含量变化范围为309.088 0~395.853 2mg·kg^(-1)、301.294 2~365.353 0mg·kg^(-1),平均值分别为352.470 6、333.323 6mg·kg^(-1)。分析发现,石榴果园土壤中除速效钾含量偏高外,有机质、全氮、速效氮含量偏低,速效磷含量中等,石榴园土壤养分不平衡。该试验为今后石榴园土壤合理施肥提供科学依据。To understand the soil nutrient status Xinjiang pomegranate main producing areas.Laboratory analysis of pomegranate orchards soil in different ages 0-20 cm,20-40 cm range of soil organic matter,total nitrogen,available nitrogen,P and K were determined.The results showed that the range of soil organic matter with different soil depth and different age were between 0.576 0-0.659 5g·kg^（-1）,0.402 5-0.504 0g·kg^（-1）,mean range were 0.617 8,0.453 3mg·kg^（-1）,separately.The range of soil total nitrogen were 0.069 5-0.072 5 mg·kg^（-1）,0.058 5-0.060 5mg·kg^（-1）,mean range were 0.071 0、0.059 5mg·kg^（-1）,separately.The range of soil available nitrogen were54.079 0-63.106 0 mg·kg^（-1）,52.091 0-57.153 5 mg·kg^（-1）,mean range were 58.592 5,54.622 3 mg·kg^（-1）,separately.The range of soil available phosphorus were 32.362 5-36.704 0mg·kg^（-1）,19.683 5-22.042 5mg·kg^（-1）,mean range were 34.533 3、20.863 0mg·kg^（-1）,separately.The range of soil available potassium were 309.088 0-395.853 2mg·kg^（-1）,301.294 2-365.353 0mg·kg^（-1）,mean range were 352.470 6,333.323 6mg·kg^（-1）,separately.After testing analysis found that,in addition to pomegranate orchard soil outside the high potassium content,organic matter,total nitrogen,available nitrogen was low,medium available phosphorus,pomegranate soil nutrient imbalances in soil for future pomegranate rational fertilization provide a scientific basis.
