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.
