摘  要:
The study on the viroses in the sun-cured tobacco (Nicoti-ana) was made in Shifang county from 1982-1984. The tobacco viroses showed three types of symptoms which were most damaging to the sun-cured tobacco. These types were the mosaic, the vein-spoted and the scorch-spoted. The pathogens of the viroses for all three types were determined to be the linear virus, the lengths for most of them were about 700×11-12nm, and they belonged to PVY group. According to the field tests, adopting the comprehensive complete sets of agricultural techniques, in which increasing the rate of potassium is the most important, can reduce the losses of the sun-cured tobacco caused by the viroses.
