我县甘薯种植面积占全县粮地面积百分之三十左右。几年来,甘薯瘟的发生、蔓延,给我县甘薯生产带来了很大的损失。在与甘薯瘟作斗争的过程中,我们初步摸清了甘薯瘟的发生为害情况、传播途径与发病规律,并总结了群众的防治经验,为消灭甘薯瘟提供了依据。 My county sweet potato acreage accounted for 30% of the county’s grain area. Over the past few years, the occurrence of sweet potato blast, spread, to my county sweet potato production has brought great losses. During the struggle against sweet potato plague, we initially found out the harm situation, the route of transmission and the incidence of sweet potato plague, and summed up the people’s prevention and control experience, which provided the basis for the elimination of sweet potato plague.
