上海地区素有栽培秋番茄的习惯,每年栽种1500～2000亩,一般亩产2000斤。由于番茄病毒病的危害,产量急剧下降,面积也日益减少。近年来,选择适宜的一代杂种和加强了田间管理,产量、面积又逐年增加。根据几年来的调查和分析认为,病毒病的为害程度是影响秋番茄产量的主要因素。室内人工接种鉴定表明,秋季番茄病毒病以黄瓜花叶病毒(CMV)为主,田间发病症状为矮丛、蕨叶和条斑等三种类型;其次是品种的早熟性不够理想,霜前红果率在20%左右,经贮藏,损耗较大,且果实品质下降;再次
The habit of cultivating autumn tomatoes in Shanghai is planted with 1500-2000 mu per year and 2,000 kg per mu. Due to the hazards of tomato virus disease, the output dropped drastically and the area was also declining. In recent years, the selection of the appropriate generation of hybrids and to strengthen field management, production, area and increased year by year. According to several years of investigation and analysis, the degree of virus damage is the main factor affecting the yield of autumn tomato. Indoor artificial inoculation identification showed that the autumn tomato virus disease was dominated by cucumber mosaic virus (CMV), and the symptom in the field was three types of short plexus, fern leaf and streak, followed by less premature varieties, Rate of about 20%, after storage, loss greater, and the decline in fruit quality; again
