Abstract:
Soil nematodes played significant roles in the agroecosystems , except some plant parasitic nematodes can infestin crops .Relationships between nematode community structure and bio -diversity with bio -nematicide were examinedin soybean plots on meadow brown soil in Shenyang city , China .Bio -nematicide ”Doufeng No .1” were inventedby Plant Nematology Laboratory , Shenyang Agricultural University .The result indicated :whether in the CK plots ortreatment plots , plant parasites nematodes , being dominant trophic groups , were inhibited across the whole growing periodsof soybean , while fungivores and omnivores -predators were the least abundant groups .The total numbers of nematode, trophic groups and bio -diversity indices(H′, J′, λ, PPI)were significantly different between sampling dates (P<0 .01)except for SR and MI (P <0 .05).Bio -nematicide were not only beneficial to decrease plant -parasites , butalso beneficial to keep the ecological balance and stability of soil nematodes .Among the indices tested , H′, SR and MIwere effective in analyzing bio -nematicide influenced soil nematodes .
