| 摘 要： | 带状种植是1种以固N植物篱为核心、农作物与植物篱相间种植的农林复合经营模式，植物篱通过修剪避免对农作物遮光，其枝叶作为覆盖物和有机肥，可提高土壤肥力。阐述了植物篱枝叶N素矿化和利用、枝叶有机碳矿化及其对土壤有机质的影响以及固N植物篱对土壤P素和其他矿质元素的供给状况，并评价了该模式下土壤养分和有机质动态。

| Abstract: | Alley cropping is the farming system growing food crops between hedgerows of trees or shrubs(nitrogen fixing species). The hedgerows in the systems are regularly pruned to prevent shading companion crops and to provide prunings for mulch and manure to improve soil fertility. Nitrogen mineralization of branch and leaf of hedgerow, organic carbon mineralization of branch and leaf of hedgerow and its effects on soil organic matter as well as the supply situation of hedgerow on soil phosphorus and other mineral element were expounded. The dynamics of soil nutrien and organic matter under the system were reviewed. |
