不同改良措施下土壤团聚体组成与稳定性分析OACHSSCD

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.
