The invention provides a soil improvement agent for preventing clubroot of rape, and the soil improvement agent comprises a compound bactericide which is prepared from tetrahydro-3, 5-dimethyl-2H-1, 3, 5-thiadiazine-2-thione, diallyl thiosulfinate and calcium cyanamide. The mass ratio of the tetrahydro-3, 5-dimethyl-2H-1, 3, 5-thiadiazine-2-thione to the diallyl thiosulfinate to the calcium cyanamide in the compound bactericide is (1 to 4.5) to (1.5 to 2.5) to (1 to 4.5). The soil conditioner can effectively prevent clubroot of rape and improve the flora structure of soil at the same time. In addition, the invention also provides application of the soil conditioner in prevention of clubroot of rape.
