图3 不同施肥处理下各团聚体内的土壤线虫营养类群相对丰度。不同大写字母表示各施肥处理下的线虫营养类群相对丰度差异显著(P < 0.05); 不同小写字母代表原状土与不同粒径团聚体下的线虫营养类群相对丰度差异显著(P < 0.05)。BS: 原状土; LA: 大团聚体; SA: 小团聚体。CK、NPK、BCNPK、OMNPK、RSDNPK、PP、OP、FU、BA见表1。

Fig. 3 Relative abundance of soil nematode trophic groups within aggregates in different fertilization treatments. Different capital letters represent significant differences in relative abundance of nematode trophic groups under different fertilization treatments (P < 0.05). Different lowercase letters represent significant differences in relative abundance of nematode trophic groups within aggregates under different fertilization treatments (P < 0.05). BS, Bulk soil; LA, Large aggregate; SA, Small aggregate. CK, NPK, BCNPK, OMNPK, RSDNPK, PP, OP, FU, BA see Table 1.
