摘　　要：为探寻八角炭疽病Colletotrichum horii绿色防控途径,研究采用单因素完全区组随机设计,在发病林区施用不同配方肥料,测定对病害控制效果、叶片生理生化指标变化以及在生产上扩大试验示范。结果表明:不同配方肥料对病害的控制效果不同,配方1(N+P_(2)O_(5)+K_(2)O 35%,有机质15%,有效钙、镁、硼、锌、铜含量3 902 mg/kg,含生防菌、肥料增效剂及复合杀菌剂)的病情指数最低,防治效果达65.65%;配方1处理的POD、SOD活性、百叶鲜质量和MDA含量与其它处理差异显著;配方1在4个不同区域点大面积试验示范,病害控制效果在79.65%以上。通过不同肥料配方处理后,对八角炭疽病的防治均有一定效果,以配方1效果最为明显,具有应用价值。In order to explore the green prevention and control of Colletotrichum horii,this study adopted a single-factor complete block random design,applied different formulas of fertilizers in the diseased forest area,measured the effect on disease control,the change of leaf physiological and biochemical indexes,and expanded the experimental demonstration in production.The results showed that different formulas had different effects on disease control,and the disease index of formula 1(N+P_(2)O_(5)+K_(2)O 35%,organic matter 15%,effective calcium,magnesium,boron,zinc and copper content 3902 mg/kg,including biocontrol bacteria,fertilizer synergist and compound fungicide)was the lowest,and the prevention and control effect reached 65.65%.The contents of POD,SOD activity,fresh weight of louvers and MDA in Formula 1 treatment were significantly different from those of other treatments.Formula 1 was tested and demonstrated in a large area in 4 different regional points,and the disease control effect was above 79.65%.After treatment with different fertilizer formulations,it has a certain effect on the prevention and control of anise anthracnose,and the effect of formula 1 is the most obvious and has application value.
