Relationship between production input and secondary succession of earthworm population in salinity transforming region of North China-A case study in Quzhou County

Abstract

Abstract: 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.
