| 摘 要： | 以郑单958为试料,研究了7个播期对玉米粗缩病发病率及产量性状的影响。结果表明：播种期与病害的发生关系密切。5月11日春播（早播）或6月15日以后麦后播种发病轻,减产少;5月18日、5月25日、6月1日、6月8日套种发病重,减产多。据此,提出适当调整播种期、改变种植模式,采用早播或者麦后直播、适当晚收的种植模式,可避免或减轻粗缩病的危害,提高玉米产量。

| Abstract: | Using Zhengdan 958 as material,the effects of 7 sowing dates on maize rough dwarf disease incidence rate and yield traits were studied.The results showed that the disease incidence was closely related with sowing date.When the maize was sown on May 11or after June 15,the incidence rate and yield loss were lower.On the contrary,when the maize was interplanted on May 18,May 25,June 1 or June 8,the incidence rate and yield loss were higher.So adjusting the sowing date,changing the planting pattern and harvesti... |
