[Relationship between production input and secondary succession of earthworm population in salinity transforming region of north China--a case study in Quzhou County].
摘要
The analysis on earthworm diversity in the farmland ecosystem of salinity transforming region in Quzhou County, Hebei Province, showed that the secondary succession of earthworm population had a close relationship with the input of fertilizer and manure. An optimum input, especially manure input, could accelerate the secondary succession. The general trend of earthworm distribution was in the order of second experimental district > first experimental district > third experimental district > original area. The distribution, biomass and amount of earthworm varied in different types of land-use, and the relationship was in the order of vegetable field > crop field > orchard and margin land.
