- 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0~20 cm、20~40 cm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 5 g?kg-1、0.402 5～0.504 0 g?kg-1，平均值分别为0.617 8、0.453 3 g?kg-1；土壤全氮含量变化范围分别为0.069 5 ～0.072 5 mg?kg-1、0.058 5~0.060 5 mg?kg-1，平均值分别为0.071 0、0.059 5 mg?kg-1；土壤速效氮含量变化范围分别为54.079 0～63.106 0 mg?kg-1、52.091 0～57.153 5 mg?kg-1,平均值分别为58.592 5、54.622 3 mg?kg-1；土壤速效磷含量变化范围为32.362 5～36.704 0 mg?kg-1、19.683 5～22.042 5 mg?kg-1,平均值分别为34.533 3、20.863 0 mg?kg-1；土壤速效钾含量变化范围为309.088 0～395.853 2 mg?kg-1、301.294 2～365.353 0 mg?kg-1,平均值分别为352.470 6、333.323 6 mg?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。
- Abstract:
- 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 5 g?kg-1,0.402 5-0.504 0 g?kg-1, mean range were 0.617 8,0.453 3 mg?kg-1, separately. The range of soil total nitrogen were 0.069 5-0.072 5 mg?kg-1,0.058 5-0.060 5 mg?kg-1, mean range were 0.071 0、0.059 5 mg?kg-1, separately. The range of soil available nitrogen were 54.079 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 0 mg?kg-1,19.683 5-22.042 5 mg?kg-1, mean range were 34.533 3、20.863 0 mg?kg-1, separately. The range of soil available potassium were 309.088 0-395.853 2 mg?kg-1，301.294 2-365.353 0 mg?kg-1,mean range were 352.470 6,333.323 6 mg?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.
