摘　　要：利用单因素试验与正交试验相结合的方法,对辣椒疫病生防菌BS04的培养基成分进行了优化。单因素试验结果表明,碳源为蔗糖、氮源为蛋白胨和无机盐为MgSO4时有利于生防菌BS04的生长。正交试验结果表明,培养基的最优组合为蔗糖2%、蛋白胨0.5%、MgSO41.5%,在此条件下生防菌BS04抑菌效果提高20%。The experiments with single factor and orthogonal design were conducted to potimize the medium of bio-control bacteria BS04 against Phytophthora capsici.The results of single factor test indicated that carbon source'sucrose',nitrogen source'peptone'and inorganic salt'MgSO4'were beneficial to the growth of BS04.The results of orthogonal tests showed that the optimal medium comprised of sucrce 2%,peptone 0.5% and MgSO41.5%.Inhibition rate of BS04 growing on the optimal medium was 20% higher than the initial medium.
