| 摘 要： | 利用29a的长期定位试验,对不同的施肥方式下农田黑土酶活性及肥力进行了研究,探讨长期施肥对土壤酶活性及与土壤肥力的影响。结果表明,化肥与有机肥配合施用能明显提高土壤有机质、全氮、全磷、碱解氮、有效磷含量,增强土壤脲酶、磷酸酶、转化酶、过氧化氢酶、脱氢酶活性。相关分析结果显示,土壤脲酶、磷酸酶、转化酶、过氧化氢酶活性与有机质、全氮、全磷、有效磷、碱解氮呈显著正相关。土壤脲酶、磷酸酶、转化酶、过氧化氢酶综合活性可以反应长期施肥后农田黑土质量的变化趋势。

| Abstract: | Soil enzyme activities and soil fertility were studied to explore the long-term fertilization on soil enzyme activities and its relationship with soil fertility based on the 29-years long-term site-specific experiment with different fertilization methods.The results showed that combined application of chemical fertilizers and organic manure could significantly increase the soil organic matter,total nitrogen,total phosphorus,alkali-soluble nitrogen,available phosphorus content and enhance the soil urease,phosphatase,invertase,catalase,dehydrogenase activity.The correlation analysis showed that soil urease,phosphatase,invertase and catalase activity positively corrected with organic matter,total nitrogen,total phosphorus and alkali-soluble nitrogen significantly.Thus the integrated activities of soil urease,phosphatase,invertase,and catalase can reflect the changing of black soil quality in the farmland after long-term fertilization. |
