rhizoshpere根际; 后面两个最好给出语境,要不合成词很难翻译

detritusphere估计是掉落物形成的环境
drilosphere看来是土壤动物形成的孔道

那个drilosphere在维基百科全书上有介绍,英文如下

The drilosphere is the part of the soil influenced by earthworm secretions and castings.[1] Specifically, it is the fraction of soil which has gone through the digestive tract of earthworms;[2] or the lining of an earthworm burrow.[3] The average thickness of the drilosphere (lining of an earthworm burrow) is 2mm.[4]

Through the drilosphere, earthworms influence soil microbial communities, with effects on microbial processes related to soil organic matter and nutrient dynamics.[5] A study of one soil type found contained within the drilosphere 40 per cent of the aerobic (and 13 per cent of anaerobic) nitrogen-fixing bacteria and 16 per cent of the denitrifiers.[6] The drilosphere is generally richer in nitrogen, phosphorus, and humified organic material than the surrounding soil. This is probably because earthworms preferentially ingest plant reside such as leaf and root litter, or occasionally fungi.[5]

The term was coined by M. B. Bouché
