摘要
研究在烤烟漂浮育苗中,TMV通过营养液途径侵染烟苗发病、通过剪叶传播扩散该病和药剂防治该病情况。营养液中污染TMV、剪刀上带有TMV和病、健烟叶接触摩擦都是该病侵染、扩散的有利途径,对剪叶剪刀用肥皂水、漂白粉或毒消等消毒2min能有效预防该病在剪叶途径中的传播。24%毒消水乳剂、0.5%OS-施特灵水剂在病毒侵染烟苗之前施用有一定的预防作用。
This paper studies clearly that the incidence & epidemic pattern and the main control technique for tobacco mosaic virus(TMV) in floating-seedling system. Meanwhile the main technical measures which are proposed to control TMV occurred in floating-seedling system.
