Abstract By pot experiments method，this paper studied the effect of earthworm activities on the
growth，yield，soil bulk density，rhizosphere microflora of continuous-cropping lily，and Fusarium
wilt control．The paper also analyzed the correlation between continuous-cropping lily Fusarium wilt and
rhizosphere soil biological characteristics．The results showed that the control effect of earthworm inoculation
on Fusarium wilt in continuous-cropping lily was obviously better than that of applying earthworm dung．
Comparing with the application of chemical fertilizer treatment，its wilt control effect was 53.42%，and lily
yield increases was 9.94%．The earthworm activities could increase soil moisture content，total porosity，
which are beneficial for seedling emerge ahead of schedule and growth，development of continuous-cropping
lily．Furthermore，earthworms activities had significantly enriched the count of bacterium and actinomycetes
in rhizosphere soil，while effectively brought down the number of fungus including Fusarium，thus reduced
the incidence rate and disease index of continuous-cropping lily wilt．To sum up，earthworm activities can
optimize the soil physical and chemical properties and microbial flora，reduce the occurrence of Fusarium wilt
in continuous cropping lily，and alleviate the obstacle for lily continuous-cropping．
