七十年代期间,宜昌地区晚稻秧苗常常遭受稻蓟马的严重危害,如防治不及时,不仅影响秧苗素质,甚至成片枯死,翻耕毁种。为了解决晚稻秧苗虫害问题,培育壮秧,我们自1979年开始,连续6年进行晚稻秧田根区施药试验、示范和大面积推广工作,取得了显著的防治效果。一、施药方法晚稻秧田,每亩用3%呋喃丹颗粒剂4斤,与湿润细黄土(每亩60—70斤)拌均匀,在整好秧田,平板后排水,将毒土均匀散在畦面上,再用木板推一下,随即播种。
During the 1970s, the late rice seedlings in Yichang often suffered serious damage from the rice thrips. If they were not controlled in time, they not only affected the quality of the seedlings, they even died in patches and were destroyed by tillage. In order to solve the problem of late rice seedling pest and cultivate strong seedling, we started to test, demonstrate and popularize the seedling root application in late rice seedling for 6 consecutive years since 1979, and achieved remarkable control effect. First, the method of application Late rice seedling, with 3% carbofuran granules per mu 4 kg, and wet fine loess (60-70 kg per acre) mix evenly in the fine seedling, flat drainage, the soil evenly dispersed 畦Surface, and then push the board, then sown.
