淄博地区玉米粗缩病高发原因分析及综防技术研究

玉米粗缩病（Maize rough dwarf fijivivus，MRDV）是我国北方玉米生产区流行的重要病害。MRDV属于植物呼肠弧科病毒组．是一种具双层衣壳的双链RNA球形病毒，由灰飞虱以持久性方式传播。经多点调查，近几年淄博地区玉米粗缩病日趋严重，局部地区爆发成灾，几近绝产。因此．控制该病害蔓延是我市玉米生产上急待解决的问题。我们在参考相关科技文献的基础上，经立项研究分析认为，防治核心以减少初侵染源生态防治为主，利用MRDV传播途径单一以及同一品种不同阶段其抗病性显著不同特点，采取适时晚播，优选抗病品种，配套化学药效防治等一系列辅助措施避免其危害。

MRDV Zibo area analysis and a high incidence of IPM Research

MRDV （Maize rough dwarf fijivivus） is corn-producing areas of northern China the importance of disease prevalence. Reovirus plants belonging to MRDV arc Branch viruses is a double layer of spherical capsid of double-stranded RNA viruses, by striatellus to persistent modes. After more investigation, in recent years Zibo MRDV region is getting more serious, the outbreak of rains in some areas, almost no middle class. Therefore, the spread of disease control in a timely and resolve maize rough dwarf disease is once again high on agricultural production in our city that need to be resolved. With reference to the relevant scientific literature and research and analysis projects that the fight against the core so as to reduce the source of primary infection prevention and control of ecological-based, MRDV use the characteristics of a single route of transmission, with the same species, stage of disease resistance varies significantly with Appropriate extension of planting resistant varieties preferred, effect of chemical control, such as supporting a range of support measures to avoid endangering the latter.
