摘要: 为明确生防菌剂对常见烟草病害的影响,本研究选取了5种常见生防菌剂分析其对烟草病害及农艺性状的影响,结果显示枯草芽孢杆菌和侧孢苏云金复合菌对烟草病毒病、烟草野火病和烟草赤星病有较好防效.进一步对比2种生防菌剂灌根和叶面喷施不同时期、不同施用方法对烟草病害发生以及农艺性状的影响,发现枯草芽孢杆菌最佳施用时期以及最佳施用方式分别为旺长中期和叶面喷施处理;侧孢苏云金复合菌最佳施用时期以及最佳施用方式为旺长中期和灌根处理,在该时期二者能显著降低烟草病害的发生,并提高烟草农艺性状,该研究为生防菌防治烟草病害并提高烟草农艺性状提供了理论基础.

Abstract: In order to clarify the effects of biocontrol agents on common tobacco diseases, five biocontrol agents were selected in this study, and their effects on tobacco diseases and agronomic characters were analyzed. It was found that Bacillus subtilis and Bacillus thuringiensis had good control effects on tobacco virus disease, tobacco wildfire disease and tobacco brown spot disease. The effects of the two biocontrol agents on the occurrence of tobacco diseases and agronomic traits were further compared between root irrigation and foliar spraying in different periods and with different application methods. It was found that the best application period and the best application method for control of Bacillus subtilis were the middle growth stage and foliar spraying treatment, respectively. The best application time and the best application method for control of Bacillus thuringiensis were the middle growth stage and root irrigation treatment, respectively, which could significantly reduce the occurrence of tobacco diseases and improve the agronomic characteristics of tobacco. This study provides a theoretical basis for tobacco disease control and improvement of tobacco agronomic characters.
