| 摘 要： | 玉米粗缩病是危害玉米生产的一种重要病毒病，历史上曾有几次大发生，近几年又呈上升趋势。引起该病害的病毒属于呼肠孤科斐济属。主要由灰飞虱以持久性方式传播。毒源、介体、品种是病害发生的必要条件，三者都达到一定的程度、数量则会引起病害流行。影响这三个条件的因素是多方面的，包括气象因素、耕作栽培措施、栽培感病品种等。针对这些因素提出压低毒源、虫口密度并种植抗耐病品种的综合防治措施

| Abstract: | Maize rough dwarf disease is an important disease on maize.It has seriously happened for a few times in histoty,particularly in recent years. The pathogen of this disease is belong to Reoviridae Fiji genus. The vector is mainly Laodel phaxstriatellus(Fallen),persisting spread. Virus original,vector and susceptible varieties are essential for the occurrence of the disease. When the three requirements come to an ideal quality, the disease will spread. Many factors affect the three requirements, such as meteorology factors, varieties and methods of cultivation and planting. Aiming at these factors, we put forward some defending strategies, including of reducing virus original and vectors, planting resistant disease varieties. |
