南京市郊栽种較普遍的瓜类植物中都有花叶病的为害。1956—57年的調查,一般发病率有5—10%,个别田地可达15%以上。每年因此而造成的損失也相当重大。为了搞清病原的种类,为病害的防治研究提供資料,进行了病原病毒的分析工作。由于收集的地区不广,所采样本不多,代表性是不够的。现将初步結果报告于下: Nanjing suburbs of the more common melon plants are mosaic disease damage. In the 1956-57 survey, the prevalence was 5-10%, with individual fields up to 15% or more. Each year the resulting loss is also quite significant. In order to clarify the types of pathogens, to provide information for the prevention and treatment of disease, the analysis of the pathogenic virus. Since the area collected is not extensive, there are not many samples collected and the representation is not enough. The preliminary results are reported below:
