摘要：

该试验采用土柱室内模拟的方法,旱地土壤上分别添加不同比例的生物炭（0、0.5%、2%、4%、6%、8%）,通过模拟降雨淋洗,探讨生物炭对旱地土壤氮素动态变化的影响。结果表明:添加生物炭能延缓NO3-和总氮淋洗速度,生物炭添加质量百分数达2%及以上时,可显著降低总氮和NH4+淋洗,其添加质量百分数达4%及以上时,可显著降低NO3-淋洗,而添加少量生物炭对氮的淋洗无影响;NO3-淋洗量占旱地土壤氮素淋洗总量的84%90%,而NH4+仅占0.4%2%;各处理下不同土层间土壤全氮含量均无差异,而不同处理间土壤全氮含量差异显著,当生物炭添加质量百分数达2%及以上时,土壤全氮含量随生物炭添加量的增加而增加,且生物炭添加百分数与土壤全氮之间满足极显著的指数关系（R2=0.9944）。因此,在旱地土壤上施用生物炭量至少达2%以上才能显著减少氮素淋洗和增加土壤全氮含量,达到减少土壤氮素损失和提高氮素利用率,减少由氮素带来的环境污染以及改善土壤肥力的综合目标。
