| 摘 要： | 为了探索幼龄油棕园间套种菠萝对土壤养分以及酶活性的影响，采用大田试验，在油棕与不同品种菠萝间套种种植模式下比较分析油棕园土壤养分及土壤酶活性大小。结果表明：间套种菠萝能够降低土壤pH值，有机质含量间套种处理与对照差异不明显，菠萝收获期较生长期有机质含量提高。土壤碱解氮、有效磷含量间套种处理要高于对照，土壤速效钾生长期间套种处理高于对照，成熟期处理与对照间差异不显著。间套种处理整体上降低土壤脲酶和酸性磷酸酶的活性，但却提高了过氧化氢酶的活性。

| Abstract: | In order to explore the effect of oil palm-pineapple intercropping on soil nutrition and soil enzyme activity, a field experiment was conducted to study the effect of soil nutrition and enzyme activities in an oil palm-pineapple intercropping system. Results showed that: the intercropping treatment could reduce soil pH; organic matter content displayed no significant difference between treatment and control, while the content in harvest period was higher than growing period. Soil nitrogen, phosphorus content in treatment was higher than in control, and soil potassium in treatment was higher than in control during growing period, while there was no significant difference between treatment and control in harvest period. The intercropping treatment reduced soil urease and phosphatase activity overall, meanwhile increased catalase activity. |
