摘　　要：2009—2012年连续4年，对潍坊市不同玉米播期的玉米粗缩病发病情况及玉米产量进行了研究。结果表明：郑单958在6月15日以后、金海5号在6月5日之后播种粗缩病发病率明显降低，5月25日套种玉米发病率最高，且在5月25日播种玉米产量损失最大。因此，播期是影响玉米粗缩病发生的重要影响因素，选择适宜品种适当晚播，可预防玉米粗缩病的爆发。From 2009 to 2012, maize rough dwarf disease incidence and yield at different sowing time were studied for 4 consecutive years in Weifang city. The results showed that：the Zhengdan 958 sowing after June 15th,Jinhai 5 sowing after June 5th, the incidence of rough dwarf disease was significantly reduced, and when maize inter-planted on May 25th,the highest incidence happened, that was not suitable for sowing, and the maize yield reduction was greatest on May 25th. Therefore, sowing date is an important factor affecting the occurrence of maize rough dwarf, selecting suitable varieties properly and lately sowing, can prevent maize rough dwarf disease.
