有机物料对风沙土主要物理性质的影响

Effect of Organic Manure on Main Physical Properties in Wind Blown Soil

通过3年有机物料培肥试验,研究了施用有机物料对风沙土主要物理性质的影响。结果表明,施加有机物料能明显降低风沙土中沙粒的含量,提高粘粒和物理性粘粒含量。>5mm及>0.25mm团聚体总量也明显增加。同时有机物料培肥还可以降低土壤比重和容重,提高土壤孔隙度与孔隙比。

Three years experiments were conducted to study the effects of organic manure ap-plication on main physical properties in wind blown soil.The result showed that the content of sand was decreased;the contents of clay particle,physical clay,>5mm and>0.25mm of cluster were increased by organic manure application.At the same time,the soil volume weight and specific weight were decreased,but the porosity and void ratio were increased.
