摘要:: 作为一种典型的玉米病害，粗缩病的发病机理研究及防治近年来逐渐受到重视。粗缩病主要通过灰飞虱进行传播，但存在全年病害循环的特点。发病后，植株呈现出严重矮化且抽穗困难，产量严重降低，尤其是在苗期感染的植株基本不能存活。在粗缩病的防治上，首先可以根据病害的诱发因素进行综合防治，如调整播期与播种环境，改善土壤情况等；对于粗缩病的高发地区，则应当通过药物手段进行防治，采用播前拌种、包衣等方式提高幼苗的抗病能力。

Abstract:: As a typical maize disease, the pathogenesis research and prevention of crude shrinkage dis? ease have been paid more and more attention in recent years. Coarse - shrinkage disease is mainly transmitted by fly lice, but it has the characteristics of annual disease cycle. After the onset of the dis? ease, the plants showed severe dwarfing and the difficulty of panicle, and the yield was severely re? duced, especially in the seedling stage. In the prevention and treatment of crude disease, the prevention and control of the disease can be carried out firstly, such as adjusting sowing time and seeding environ? ment, improving soil condition, etc. For the high incidence area of crude disease, the prevention and treatment should be carried out by means of drug treatment, and the disease resistance of seedlings should be improved by mixing and dressing before planting.
