摘要

以19年的长期定位施肥土壤为材料

研究不同施肥管理:不施肥(CK)

施无机肥(N、NP、NK、NPK)

施有机肥(OM)

有机-无机配施(F、F’)下稻田耕层土壤有机碳库组分及含量变化。结果表明:不同施肥方式对土壤有机碳及其组分有显著影响

土壤总有机碳(TOC)变化趋势为有机无机配施(平均12.34g/kg)>单施有机肥(平均12.15g/kg)>无肥(平均10.56g/kg)>化肥(平均9.78g/kg);有机肥和化肥配施土壤微生物量碳(SMBC)、水溶性有机碳(WSOC)、轻组有机碳(LFOC)及SMBC/TOC、WSOC/TOC、LFOC/TOC均显著高于单施化肥土壤的。与不施肥相比

化肥、有机肥的施用均显著增加了土壤重组有机碳(HFOC)和HFOC/TOC

其中

化肥的施用更有利于土壤重组有机碳(LFOC)的积累。单施有机肥或有机无机配施显著增加了较大粒级(>0.25mm)水稳性团聚体及其TOC含量

而单施化肥则显著增加了较小粒级(<0.25mm)及其TOC含量。因此

长期施用有机肥

特别是有机肥与无机肥配施能提高土壤活性碳含量和土壤团聚体稳定性

从而保持和提高了土壤质量和持续生产力。

Abstract

A long-term(19-year) fertilization experiment was conducted to study the effects of different fertilization system on soil carbon stock and fractions.The results showed that effect of different long-term fertilization on soil carbon stock and fractions was significant.Contents of soil total organic carbon(TOC) in different fertilizations decreased in an order of combined manure and inorganic fertilizer(average 12.34 g/kg)>single organic fertilizer(average 12.15 g/kg)>no fertilizer(average 10.56 g/kg)>single...
