摘　　要：采用三元二次回归正交旋转组合设计方法,确立了黄连、黄芩提取液与二氧化氯对甘蓝链格孢菌抑制效果最佳的复配组合:黄连提取液13.48%、黄芩提取液15.56%、二氧化氯0.14%。用此复配剂浸种,芸苔链格孢菌和甘蓝链格孢菌的侵染率分别降低了97.33%和94.85%,且提高了种子发芽势及萌发相关酶活性。With the method of the quadratic orthogonal rotational combination design with three factors, the best inhibition of mixture of Coptis Chinensis Franch extraction solution, Scutellaria baicalensis extraction solution and Chlorine dioxide on Alternaria brassicicola were quantified： the mixture of 13. 48% Coptis Chinensis Franch, 15. 56% Scutellaria baicalensis and 0. 14 % Chlorine dioxide showed the best; seeds soaking with this mixture, the infection rates of Alternaria brassicae and A. brassicicola were conspicuously decreased by 97.33% and 94. 85% compared with control （n= 4, P〈 0. 05）,the seeds germination were promoted and the correlative enzymes activity of seeds germination were increased. The research provided the scientific basis for the biological agents development of seed treatment on cabbage Seed-borne Black Spot Disease.
