    摘要:

    [目的] 对东北黑土区植物篱种植模式的土壤渗透性进行研究,为黑土区坡耕地水土流失治理提供科学依据。[方法] 通过小区试验开展研究。[结果] 植物篱模式能够减小土壤容重,提高土壤孔隙度,显著增加土壤的入渗能力,进而减少水土流失;篱带部位的入渗能力大大高于篱间部位,不同品种植物篱渗透性能排序为:黑豆果 > 短梗刺五加 > 桑树,植物篱土壤入渗受地面坡度影响,小坡度的土壤入渗率高于大坡度。[结论] 植物篱作为一种水土保持新措施,具有改善土壤结构,增加土壤入渗,减少地表径流,防治水土流失的作用,应在黑土区开展广泛的研究与推广。

    Abstract:

    [Objective] The soil infiltration rates under hedgerows in chernozem sloping farmland were studied to provide scientific basis for soil erosion control of sloping farmland in the chernozem area of Northeast China. [Methods] Plots experiment were conducted.[Results] Soil loss was decreased resulting from the decrease of soil bulk density and the increase of soil porosity and infiltration. As compared to the one of inter-hedgerow, the soil infiltration rates in the hedgerow increased markedly. Infiltration rate varied with the change of vegetation, had a rank as followed: blackcurrant > short carpopodium acanthopanax > mulberry. Besides that, it was also affected by slope steepness, the lower of slop steepness, the higher of soil infiltration rate. [Conclusion] As a measure of soil and water conservation, hedgerow could improve soil structure, increase soil infiltration rate, subsequently decrease surface runoff and soil loss. It should be applied in the chernozem area of Northeast China.
