大棚西葫芦病毒病一般在缺水缺肥、管理粗放,高温干旱、日照过强、蚜虫为害重等情况下均有利于发病。由于大棚环境密闭,若不控制好棚内小环境,全年均可发病。植株若在坐果前发病,则花器发育不良,影响坐果,降低蔬菜质量和产量。根据田间调查情况提出以下防治措施。 1.选种目前国内栽培的西葫芦抗病品种较少,据资料介绍早青一代较抗病毒病。 2.播前种子处理晒种后将种子用60—62℃温水浸10分钟,捞出再用1%的高锰酸钾液浸种20
Greenhouse zucchini virus disease is generally lack of water and lack of manure, extensive management, high temperature and drought, too strong sunshine, aphids and other harmful cases are conducive to the incidence. As a result of airtight greenhouse environment, if not controlled shed a small environment, can be sick throughout the year. If the plant before the onset of fruit set, the flower hypoplasia, affecting fruit set, reduce vegetable quality and yield. According to the field survey to propose the following prevention and control measures. 1. Selection Currently cultivated zucchini disease-resistant varieties less, according to the information on the young generation than the anti-virus disease. 2 sowing seed treatment after drying the seed with 60-62 ℃ warm water soak for 10 minutes, remove and then 1% potassium permanganate soaking 20
