| 摘 要： | 【目的】综合分析华南地区不同生态类型蚯蚓对土壤团聚体分布、团聚体水稳定性以及土壤团聚体破坏率的影响,以期为蚯蚓改善土壤结构提供科学依据和理论支持。【方法】采用室内盆栽培养试验,在华南地区具有代表性的赤红壤和红壤中分别接种生态类型不同的4种蚯蚓:赤子爱胜蚓Eisenia fetida、南美岸蚓Pontoscolex corethrurus、壮伟远盲蚓Amynthas robustus和参状远盲蚓A. aspergillum,研究不同生态类型蚯蚓对土壤结构的影响。【结果】与空白对照相比,南美岸蚓、壮伟远盲蚓和参状远盲蚓的添加均显著增加了2种土壤中的大团聚体(d2 000μm)比例(P0.05),其中,赤红壤中其分别提升了35.20%、44.81%和37.88%,红壤中其分别提升了14.92%、25.31%和20.18%;与空白对照相比,壮伟远盲蚓的添加均显著降低了赤红壤水稳性大团聚体和水稳性小团聚体(250μm≤d≤2 000μm)的比例,却显著提升了赤红壤水稳性微团聚体(d250μm)的比例(37.84%,P0.05);4种蚯蚓的添加均显著提升了2种土壤的团聚体破坏率(P0.05),其中添加参状远盲蚓的2种土壤的团聚体破坏率均最低。主成分分析结果显示:在2种不同的土壤中,不同蚯蚓作用后土壤的团聚体分布和稳定性之间存在显著差异(P0.05)。【结论】华南不同生态类型的蚯蚓对赤红壤和红壤的团聚体分布和稳定性的影响不同;内栖型蚯蚓(南美岸蚓和壮伟远盲蚓)对土壤团聚体的形成和土壤结构的改善效果最好;深栖型蚯蚓(参状远盲蚓)对土壤水稳性团聚体的破坏作用最小。
