摘要：

为了明确种苗处理对麦冬生长的影响及其控病效果,指导麦冬优质安全生产。以川麦冬为供试材料,采用田间小区试验,研究了6种药剂3种种苗处理方式对麦冬种苗成活、生长和产量的影响,以及对炭疽病、根腐病的控病效果。结果表明木霉T23制剂、多抗霉素和噁霉灵处理种苗,可显著提高麦冬种苗成活率,促进麦冬分蘖、增加块根数、使块根伸长增粗,提高麦冬产量10%以上。对麦冬炭疽病以叶面喷施多抗霉素、噁霉灵的效果较好,防治效果分别为60.17%和58.25%;对麦冬根腐病以木霉T23、多抗霉素浸苗,或以噁霉灵、木霉T23灌根的效果均较好,其防治效果分别为70.06%、65.17%、72.87%和70.14%。综上,木霉23制剂、多抗霉素和噁霉灵处理种苗,可有效控制炭疽病、根腐病为害,促进麦冬生长,提高麦冬产量,在麦冬生产上具有良好的应用前景。

Abstract:

The aim is to clarify the effect of seedling treatment on the growth of Ophiopogon japonicus and its disease control efficacy, and guide the high quality and safety production of O. japonicus. O. japonicus in Sichuan was used as material, and the effects of six fungicides and three seedling treatments on seedling survival, growth and yield of O. japonicus, and the disease control against anthracnose and root rot disease were studied. The results showed that after treated with trichoderma T23, polyoxin and hymexazol, the seedling survival rate of O. japonicus was significantly improved, meanwhile the number of tillers and root tubers increased, and the root tubers were longer and thicker, and the yield increased by more than 10%. The control effect against anthracnose by foliar spraying with polyoxin and hymexazol was 60.17% and 58.25%, respectively, which were superior to those of other treatments. The control efficacy against root rot disease by seedling dipping with Trichoderma T23 and polyoxin or root irrigating with hymexazol and Trichoderma T23 was 70.06%, 65.17%, 72.87% and 70.14%, respectively, which were superior to those of other treatments. In conclusion, seedling treatment with trichoderma T23, polyoxin and hymexazol could effectively control anthracnose and root rot disease, and promote the growth and yield of O. japonicus, showing good application prospects.
