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 for four consecutive years, we studied the incidence of maize sowing disease and corn yield in different sowing dates in Weifang. The results showed that after June 15, Zhengdan 958 significantly reduced the incidence of sowing and sowing of sowing and sowing of the Jinhai No.5 after June 5, and the highest incidence of intercropping corn on May 25 and the sowing of corn on May 25 The biggest loss. Therefore, sowing date is an important influencing factor on the occurrence of maize rough-sowing disease. Choosing the appropriate sowing date for proper late sowing can prevent the outbreak of corn sickening disease.
