当前,华南早稻大部处于移栽至返青分蘖期,其中海南南部为灌浆期至黄熟期,海南中部为抽穗扬花期至灌浆期;江南早稻大部处于三叶期。受华南入汛偏早影响,今年“两迁”害虫迁入早,其中稻飞虱迁入量明显高于常年,加之未来南方早稻区降水偏多,有利于“两迁”害虫的迁入繁殖。各地应提高警惕,及时开灯,加强监测,及时发布病虫情报,切实做好“两迁”害虫监测预警工作。
At present, most of the early rice in South China is in the tillering stage from transplanting to rejuvenation. Among them, southern Hainan is from filling stage to yellow ripening stage, and central Hainan is heading-flowering stage to filling stage. Most southern early rice is in the three-leaf stage. Affected by the earlier flood season in South China, pests moved in early this year. In particular, the migration of planthoppers was significantly higher than that of perennials. In addition, the precipitation in the southern morning paddy areas would be higher in the future, which is good for the pests The move into breeding. All localities should be vigilant, turn on the lights in time, strengthen monitoring, issue pest and disease information in time, and earnestly do a good job in monitoring and early warning of pests.
