摘　　要：黄泛区土壤团聚体稳定性较差,流水对土壤的侵蚀作用较强。本文以兰考县为研究区,将沙化耕地作为研究对象,设计4个试验组,采取4种改良措施(分别施用复合肥、污泥生物质炭、鸡粪和粉碎秸秆),同时设置1个空白对照组,14个月后采集土壤样品,计算土壤团聚体组分比例,判断不同改良措施对土壤团聚体稳定性的提升效果。结果显示,施用污泥生物质炭时,土壤团聚体稳定性最好。The stability of soil aggregates in the Yellow River floodplain area is poor,and the erosion effect of flowing water on the soil is strong.Taking Lankao County as the research area and desertified farmland as the research object,this paper designs four experimental groups and adopts four improvement measures(applying compound fertilizer,sludge biochar,chicken manure,and crushed straw respectively),and sets up a blank check group,and collects soil samples after 14 months to calculate the proportion of soil aggregate components and determine the improvement effect of different improvement measures on soil aggregate stability.The results show that when applying sludge biochar,the stability of soil aggregates is the best.
