摘  要:
为了筛选防治青枯病的药肥一体化制剂,以优美利和四霉素为供试药剂,研究了不同水平的水肥一体化组合对烟草青枯病防效及经济性状的影响。结果表明:各处理的青枯病发病率在7月10日后均快速上升,与大田生产发病趋势较为一致,CK处理7月25日病株率最高,达78.30%;"优美利3 g+四霉素200倍液"的组合防治效果达69.47%,极显著高于其余处理;同时,该处理的经济性状也表现最优,产值达1 635.66元/667m~2,极显著高于其余处理。这表明施用高水平的优美利和四霉素组合来防治烟草青枯病是切实可行的。

摘  要:
In order to validate the control effects of integrated technology of medicine and fertilizer on tobacco bacterial wilt, field experiments were conducted by using grace and tetracycline as the test agents. The results obtained were listed as follows:(1) The incidence rate of bacterial wilt ascended more quickly after July 10 th,the incidence of CK reached 78.30% in July 25 th.(2) The control effect of "youmeil 3 g+tetramycin 200 times liquid"reached 69.47%, significantly higher than other treatments.(3) The output value of "Youmeil 3 g+tetramycin 200 times liquid" served as 24 534.9 yuan/hm~2, with the highest economic character in all treatments. In a word, integrated technology of medicine and fertilizer was a feasible approach to control tobacco bacterial wilt.
