水稻细菌性条斑病是国内植物检疫对象。带病的种子是初侵染源。做好制种田防治,是杜绝初侵染源的关键。但制种栽培有其特殊的管理过程,当父、母本幼穗发育差异时,要采用割叶、施用高氮素等进行花期调整,这样都会给病菌入侵蔓延创造有利的发病条件。在生产操作如何做到趋利避害,理顺防治与调整花期的矛盾。做到既增加制种产量,又杜绝种子带菌。可见,制种生产的综合防治是一门较复杂的技术。
Rice bacterial leaf streak is the object of domestic phytosanitary. Sick seeds are a source of initial infection. Good system of farming prevention and control is the key to eliminate the source of primary infection. However, seed production has its special management process, when the parent and the female parent panicle development differences, the use of cut leaves, the application of high nitrogen and other flowering adjustments, which will give the spread of germs invasion to create favorable conditions for the disease. How to Achieve the Benefit and Avoidance in Production Operations, Straighten out Contradictions between Prevention and Control and Flowering Periods. Achieve both increased seed production, but also eliminate the seed carrier. Can be seen that the comprehensive control of seed production is a more complex technology.
