不同水土保持植被对典型黑土微团聚体稳定性的影响
|
摘要
以典型黑土区落叶松人工林、水曲柳人工林和草地等水土保持植被以及耕地土壤为研究对象,通过土壤微团聚体分散系数、粒径组成以及不同粒径微团聚体有机碳质量分数的测定计算和分析。结果表明:(1)与耕地相比,所研究的3种水土保持植被均可显著增加(0.05 mm The stability of soil micro-aggregates from soil and water conservation vegetation in typical black soil region was studied by measuring, calculating and analyzing the dispersion coefficient of soil micro-aggregates, particle size composition of soil micro-aggregates and organic carbon content of soil micro-aggregates with different particle sizes. Three vegetations including Larix gmelini plantation, Fraxinus mandshurica plantation and grassland were selected as test objects, and the cultivated land was as the comparison. The results showed that :(1)Compared with cultivated land, three types of soil and water conservation vegetation can significantly increase the proportion of large-particle size micro-aggregates(0.05 mm
