农林废弃物与有机肥配施对黑土团聚体组成及稳定性的影响
Composition and stability of the aggregates in black soil amended with cattle manure mixed agricultural and forest residues
摘要
Abstract
Soil aggregates composition and stability were studied after application of cattle manure and different agricul-tural and forest residue. In this study, five treatments was as follow:( 1) modification stellerite and cattle manure( SH) , (2)corn and cattle manure(YM),(3)tree leaves and cattle manure(YS),(4)peat and cattle manure(CT), and (5)cattle manure(CK).The results showed that:>0.25 mm large aggregates of mechanical-stable and water-stable aggre-gates increased significantly compared with CK. The mean weight diameter ( MWD ) and geometric mean diameter ( GMD) of soil with organic material treatment were greater than that of cow dung, and they were significantly correlated with the content of >0. 25 mm mechanical-stable aggregates. The application of different agricultural and forest residue decreased soil aggregates fractal dimension, and unstable aggregate index. SH, YM, CT treatments improved the degree of aggregates dispersion of soil, and YM, CT treatments reduced soil bulk density. So the agricultural and forest residue treatments could not only enhance the proportion of bigger aggregates, but also improve the structure of soil.关键词
