摘　　要：筛选环保型抑菌剂,为油茶炭疽病和软腐病绿色防治提供依据。采用室内生长速率法和喷雾法测定了4种抑菌剂对油茶炭疽病菌和软腐病菌抑制作用及油茶炭疽病苗期防治效果。实验室抑菌试验结果表明,纳米氧化铁悬浮剂及油茶壳醋液对油茶炭疽病菌和油茶软腐病菌均有较好的抑制作用,其中含有壳聚糖的纳米氧化铁悬浮剂的抑制效果最好,1%纳米氧化铁悬浮剂处理对油茶炭疽病抑制率为100%,4%的油茶壳醋液处理对油茶炭疽病抑制率为100%;0.3%的纳米氧化铁悬浮剂处理对油茶软腐病的抑制率为100%,0.4%的油茶壳醋液处理对油茶软腐病的抑制率为100%。苗期试验结果显示,4种抑菌剂对油茶炭疽病菌均有很好的防治效果,以纳米氧化铁和油茶壳醋液防治效果最好,防治效果达90%左右,与电解质水溶液等处理差异显著,对照多菌灵和波尔多液防治效果亦较好,达59%以上。In order to screen environmentally friendly antibacterial agents and provide a basis for green prevention and control of Camellia anthracnose and soft rot disease.The inhibition of four kinds of bacteriostatic agents on Colletotrichum gloeosporioides and soft rot of Camellia oleifera and the control effect at seedling stage were determined by indoor growth rate method and spray method.The results showed that both nano iron oxide suspension and Camellia oleifera shell vinegar had good inhibitory effects on Camellia oleifera anthracnose pathogen and Camellia oleifera soft rot pathogen.Among them,nano iron oxide suspension containing chitosan had the best inhibitory effect.The 1%nano iron oxide suspension treatment had a 100%inhibition rate on Camellia oleifera anthracnose,while the 3%Camellia oleifera shell vinegar treatment had a 100%inhibition rate on Camellia oleifera anthracnose;The inhibition rate of 0.3%nano iron oxide suspension treatment on Camellia oleifera soft rot disease was 100%,and the inhibition rate of 0.4%Camellia oleifera shell vinegar treatment on Camellia oleifera soft rot disease was 100%.The results of seedling test showed that four kinds of bacteriostatic agents had good control effects on anthracnose of Camellia oleifera,among which nano iron oxide and Camellia oleifera hull vinegar had the best control effect,with the control effect reaching about 90%,which was significantly different from electrolyte aqueous solution,and the control effect of carbendazim and bordeaux was also good,with the control effect reaching more than 59%.
