The purpose of this study was to explore the reduction effect of reductive soil disinfestation(RSD)on soil barrier factors in continuous cropping of Chinese cabbage，and provide a theoretical basis for enriching green，effective and environmentally friendly control strategies of cruciferous crops. Six treatments were set up，including blank soil without any treatment(CK1)，soil only flooded and covered by film(CK2)，adding biogas slurry RSD treatment(adding biogas slurry to the soil to the maximum field capacity and film，BS)，adding soybean bran RSD treatment(adding 20 t/hm² soybean bran evenly to the soil after irrigation to the maximum field capacity and film，SS_RSD)，biochar repair(5 t/hm² biochar was evenly added to the soil and then irrigated to the maximum field water holding capacity and coated film，BC)，cotton dragon fumigation(adding 0.5 t/hm² cotton dragon evenly to the soil，irrigation to 60% ～ 70% of the maximum field capacity and film，DZ)，and the changes of incidence，yield，soil physical and chemical properties and enzyme activities of cabbage clubroot under different treatments were compared. The results of two consecutive trials showed that，compared with CK1 treatment，the yields of CK2 and DZ treatments increased by 1.71% ～ 2.71% and 18.74% ～25.51%，respectively，and the incidence rates decreased by 15.32% ～ 18.33% and 53.33% ～ 73.65%，respectively. The incidence of BS and BC treatment decreased by 21.32% ～ 45.00% and 35.00% ～ 35.99%，respectively，and the yield increased by 13.19% ～ 15.07% and 14.26% ～ 19.90%，respectively，compared with CK1. The control effect of SS_RSD on cabbage clubroot reached 76.89% ～ 79.31%，which reduced the incidence of cabbage clubroot by 60.00% ～ 66.99%，and increased the yield by 24.25% ～27.96%. Moreover，SS_RSD increased the contents of soil organic matter，total nitrogen，available phosphorus，and soil urease and phosphatase activities. Therefore，RSD is an effective measure to rapidly reduce the continuous cropping obstacles of Chinese cabbage and realize the healthy and efficient utilization of soil resources in facilities.
