| Abstract: | Objective The aims was to define the com prehensive effect of different sowing time, potassium fertilizer and calcium-boron ratio on rape clubroot disease. Method]Through the designs of three-factors and five-levels as well as the quadratic universal rotary assembly,regression models were built, and it was analyzed, optimized, and conducted with frequency analyses. Result] The extent of impact of all experimental factors to clubroot was sowing time（X1） 〉potassium fertilizer （X3） 〉 calcium-boron ratio（X2）. Conclusion]The optimal ratio of solution of rape root disease prevention by the three-factors, which was sowing time（X1）= Oct.10^st or Oct.11^st; boroncalcium ratio（X2）=26.85; potassium fertilizer（X3） =8.37 g/m^2. |
