摘　　要：百合病毒病症状类型可归纳为7种类型,轻花叶型(Mm),重花叶型(Sm),矮化型(Stu),丛簇矮化型(Rstu)。黄化矮化型(Ys),扁茎簇叶型(Fsbl),花变叶型(Phy),其中轻花叶型和重花叶型发生普遍,花变叶型出现较少。病害发生的轻重与种球种龄有关,种龄越大,发病越重。前茬种植百合的地块较种植小麦的地块发病重,低洼积水地发病重。不同百合品种对病毒病的抗性有差异。There are seven types of virus disease symptoms on lily plants, including mild mosaic (Mm), severe mosaic (Sm), stunting (Stu), rosette stunt (Rstu), yellow stunt (Ys), flat stem buncky leaf (Fsbl), phyllody (Phy). The symptoms of Mm and Sm were the most common symptoms in lily planting areas. The symptom of Phy was scarce. The older the bulbs, the more severe the virus disease. The disease occurred more seriously in the fields growing lily in the first stubble than in the fields growing wheat in the last stubble, whereas in the fields of low-lying and wet lands the disease is more severe. Different lily species has different resistance to viral disease.
