- 3種方法測定的團聚體穩定性指標都與土壤黏粒含量呈極顯著(zhù)相關(guān),濕篩法測定的>0.25mm團聚體含量和LeBissonnaia法測定的團聚體平均重量直徑(MWD)與土壤有機質(zhì)含量呈顯著(zhù)相關(guān).The aggregate stability indices as determined by the three methods were very significantly correlated with the clay content of Ferrisols. The amounts of aggregate with a diameter of >0.25 mm determined by wet-sieving and the mean weight diameter (MWD) determined by Le Bissonnais method were significantly correlated with organic matter content of Ferrisols.
