青椒是上海地区栽培的细菜品种之一,但若干年来,甜椒的病毒病发生严重,每到7～8月,发病率常在百分之七、八十以上。甜椒罹病后植株生长受阻,严重时显著矮化,落叶、落花、落果。病株即便能结果,果实往往小小而畸形,商品价值降低。上海市农科院植保所副研究员袁贤溶等,1984年开始该病综防研究,取得显著成绩。为此,植保所于6月22日邀请上海市蔬菜技术推广站、川沙县
Green peppers are one of the fine varieties of cultivars cultivated in Shanghai. However, for several years, the virus disease of bell peppers has become serious.
