| 中文摘要: |
| 为有效控制在有机种植模式下烟草真菌性病害，采用经有机产品认证的枯草芽胞杆菌800倍液、小苏打500倍液和板蓝根（Isatis indigotica）、金银花（Lonicera japonica〖WTBZ〗）、青蒿（Artemisia annua）和鱼腥草（〖WTBX〗Houttuynia cordata〖WTBZ〗）4种中草药提取液对烤烟白粉病和炭疽病进行田间防效研究。结果表明：鱼腥草提取液和小苏打对烤烟白粉病防治效果较好，经过2次喷药后防效分别达到66.67%和57.68%，其余药剂防效在31%以下；2次喷药后枯草芽胞杆菌对炭疽病的防治效果为57.34%，其余药剂防效均在25%以下。在有机烟叶规模生产中可使用小苏打与枯草芽胞杆菌对真菌性病害进行防治；鱼腥草具有进一步研究的价值。 |
| 英文摘要: |
| Under organic farming mode, in order to control tobacco fungal diseases effectively, Bacillus subtilis 800×, baking soda 500× and extracts of the indigowoad root Isatis indigotica, honeysuckle Lonicera japonica, Artemisia annua and Houttuynia cordata were used to control powdery mildew and anthracnose in the field. The results showed that the control effects of H. cordata extract and baking soda to powdery mildew were better than those of the other fungicides. The control effects were 66.67% and 57.68%, respectively. The control effect of B. subtilis to anthrax was 57.34%. The control effects of the others were below 25%. It is concluded that under organic farming mode, baking soda and B. subtilis could be used to control tobacco fungal diseases and H. cordata should be studied further. |
