基于Box-Behnken响应面法的补骨脂种子提取物防治苹果树腐烂病增效技术研究

Study on the synergistic technology of Psoralea corylifolia seed extract against apple valsa canker based on Box-Behnken responsesurface methodology

通过采用Box-Behnken响应面法,优化了补骨脂种子提取物涂抹剂助剂配方。当助剂中添加0.023g/mL山梨醇聚氧乙醚、0.046 g/mL聚醚改性硅油、0.005 g/mL糊精时,补骨脂种子提取物涂抹剂对苹果树腐烂病菌的抑制率可达92.52%。同时,通过田间试验,验证了补骨脂种子提取物涂抹剂对苹果树腐烂病菌的防效达90.40%,显著高于常规液态剂型。
