- Abstract:
- In recent years, the soil seed bank has been widely reported, but few studies on seed rain has been concerned. Therefore, the desert steppe in Ningxia was selected as the study site. By using the line transect method, the Petri dish for seed rain collector, the seed rain characteristics and seed rain and vegetation were studied. The results showed that seed rain covered 8 plant species, perennial herbaceous plants accounted for a larger proportion which was 62.5%; seed rain from August to October presented gradually increasing trend, in October for the seed rain scatter is the peak, from August to October, seed rain densities were (73.60 ±12.24)/m2, (77.85 ±11.81)/m2, (240.62 ±41.08)/m2, respcectively; seed rain plant density and aboveground plant density had no significant correlation; similarity of seed rain plant and aboveground plant species was 0.457, which is the lower similarity. The research results can provide reference for the studies on seed rain, seed bank, the ground vegetation interaction.
