由玉米矮花叶病毒（ＭＤＭＶ）引起的玉米矮花叶病近年在我国北方地区大范围流行成灾，给生产造成了巨大经济损失。本研究紧密结合生产实际，针对病害发生危害特点，在进行病原病毒的提纯、血清制备、检测、病害流行学系统研究的基础上，重点对种传规律和蚜虫传毒机制作了... Maize dwarf mosaic disease caused by maize dwarf mosaic virus (MDMV) has caused widespread epidemics in northern China in recent years, causing huge economic losses to the production. Based on the systematic study of epidemiology of pathogenic viruses, based on the systematic study of epidemiology of pathogenic viruses, the study focuses on the breeding laws and aphid-based virus transmission mechanisms in close connection with the actual production and the characteristics of the hazards of the diseases.
