玉米粗缩病是晋南玉米生产上发生为害最严重的病害之一。试验表明，播种期与病害的发生关系密切，4月15日春播（早播）或6月15日复播（晚播）发病轻，减产少；5月25日套种发病重，减产多。据此，提出适当调整播种期、改变种植方式的防治措施。
Maize is one of the most serious diseases in maize production in South Shanxi. Experiments show that the sowing period is closely related to the occurrence of the disease. On April 15, spring sowing (early sowing) or rewilding (late sowing) on June 15 was mild with less yield reduction. On May 25, the intercropping was heavy and the yield was reduced. Accordingly, put forward appropriate measures to adjust the planting period, change the method of planting.
