Weed soil seedbank of farmland has been considered as an important part of farmland ecosystem.Here we had collected the relevant research reports under different fertilization patterns worldwide,and then attempted to summarize the progress on the soil seedbanks density,species composition and diversity.We also proposed some perspectives on what are the problems in soil seedbank research and how to resolve them in near future,pointing out what work can be carried out on the germination of weed seed,the mechanism of soil seedbank change,the relationship with ground weed community,and the genetic variability of weed seed under different fertilization patterns.
