Abstract：In order to explore the control effect of soil fumigant on Chinese cabbage clubroot in open field production，‘Jiaobai No.1’was taken as test material to study the control effect of 98% dazomet micro granule combined with microbial soil remediation agent on Chinese cabbage clubroot and effect on soil properties．The results showed that 98% dazomet micro granule，20% calcium cyanamide granule combined with microbial soil remediation agent all had good disease control effects and growth promotion result．The morbidity and disease index at harvest stage both were significantly inferior to that of the contrast．The control effects were 73.26% and 74.42%，respectively．The net vegetable yields were significantly higher than that of contrast，43.41% and 59.51% higher than that of the contrast，respectively．There was no significant effect on soil microbial number，but has certain effect on soil physical and chemical properties，which has soil improvement effect．
