桑树萎缩病是我国桑树的重要病害之一,按其症状可分三种类型:黄化型,萎缩型和花叶型。黄化型萎缩病在江苏省为害严重,后二者则以浙江省为多。三种类型的桑树萎缩病虽然在外部症状、发病环境和抗病品种各个方面的表现均有很大差异,但都为全株性病害。关于桑树萎缩病病原的研究,虽曾做过分离,但对湖北省桑树萎缩病病原的研究,未见报道。本文主要讨论我们对湖北省桑树萎缩病病原研究的初步结果。 Mulberry atrophy is one of the important diseases of mulberry in China, according to their symptoms can be divided into three types: yellow type, atrophy type and mosaic type. Hyperthyroidism in Jiangsu Province is seriously ill, while the latter two are more than in Zhejiang Province. Although the three types of mulberry atrophy are very different in all aspects of external symptoms, disease environment and disease-resistant varieties, they are all plant disease. Although the studies on the pathogens of mulberry shrubs have been done in isolation, the research on the pathogens of mulberry shrubs in Hubei Province has not been reported yet. This article mainly discusses the preliminary results of our study on the pathogens of mulberry wilt disease in Hubei Province.
