摘　　要：以悬浮率为评价手段,探究添加组分的种类、含量对波尔多液悬浮率的影响;通过抑菌圈实验评价复配产品的协同杀菌性能;通过模拟降水评价复配产品的抗冲刷性能。结果表明,添加十二烷基硫酸钠(SDS)0.3 g/L时,有效组分的颗粒呈现3~5μm的空心线团状结构,d(0.9)为77.306μm,最大悬浮率为90.1%;抑菌圈实验发现,复配波尔多液对葡萄白腐菌(Coniothyrium diplodiella)和苹果腐烂菌(Valsa mali)的抑制率分别为84.2%和82.5%。经过室内模拟降水实验发现,新型波尔多液在叶面上的附着性能明显提升。添加SDS的波尔多液中,提升有效组分的悬浮率有利于提升杀菌性能。The effect of the types and amounts of additives on the suspension performance of the Bordeaux mixture is studied. The synergistic antibacterial activity of the compound material is evaluated by the oxford cup method. The adhesion performance is estimated by stimulating rainfall. The results show that when the concentration of SDS is 0. 3 g/L,3 -5 txm of ＂hollow ball of wool＂ structure can be observed for the effective component,with 77. 306 i^m of d （0. 9） and 90. 1% of suspension percentage. The maximum inhibition rate of the novel mixture towards Coniothyrium diplodieUa and Valsa mali are 84. 2% and 82. 5% , respectively. At the same time, the improved adhesion of hydrophilic leaves is approved in the experiments. And higher suspension percentage leads to better antibacterial activity for the SDS containing mixture.
