研究了粉壤土不同粒径团聚体反硝化潜力的空间变异性。七种骨料尺寸范围（<0.25、0.25-0.5、0.5-1、1-2、2-5、5-10和10-20 mm直径）通过对采样土壤进行温和的干筛获得。采用乙炔块法测定了不同处理条件下的反硝化速率
The denitrification potential in different size aggregates of a silt loam soil was studied to explain spatial variability of denitrification. Seven aggregate size ranges (<0.25, 0.25-0.5, 0.5-1, 1-2, 2-5, 5-10, and 10-20 mm diam.) were obtained by gentle dry sieving of the sampled soil. The denitrification rate was determined by the acetylene block method following imposition of several different treatments
