| 英文摘要 | Glomalin-related soil protein (GRSP) contributes to the formation and maintenance of soil aggregates, it is however remains unclear whether long-term intensive manure amendments alter soil aggregates stability and whether GRSP regulates these changes. Based on a three-decade long fertilization experiment in northeast China, this study examined the impact of long-term manure input on soil organic carbon (SOC), total and easily extractable GRSP (GRSP(t) and GRSP(e)) and their respective allocations in four soil aggregates (>2000 mu m; 2000-250 mu m; 250-53 mu m; and <53 mu m). The treatments include no fertilization (CK), low and high manure amendment (M1, M2), chemical nitrogen, phosphorus and potassium fertilizers (NPK), and combined manure and chemical fertilizers (NPKM1, NPKM2). Though SOC, GRSP(e) and GRSP(t) in soil and SOC in each aggregate generally increased with increasing manure input, GRSP(t) and GRSP(e) in each aggregate showed varying changes with manure input. Both GRSP in macroaggregates (2000-250 mu m) were significantly higher under low manure input, a pattern consistent with changes in soil aggregate stability. Constituting 38 similar to 49% of soil mass, macroaggregates likely contributed to the nonlinear changes of aggregate stability under manure amendments. The regulatory process of GRSP allocations in soil aggregates has important implications for manure management under intensive agriculture. |
