大棚西葫芦病毒病一般在缺水缺肥、管理粗放,高温干旱、口照过强、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,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分钟,或用10%磷酸三钠液浸种20分钟,清水冲洗后凉干播种。
Greenhouse zucchini virus disease is generally lack of water and lack of manure, extensive management, high temperature and drought, too strong mouth, aphids and other adverse damage 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. At present, there are fewer cultivars of Zucchini cultivated domestically, and the Zaogou generation is more resistant to antiviral diseases. 2 pre-sow seed treatment. After drying seeds will be 60 ~ 62 ℃ warm water soak for 10 minutes, remove and then 1% potassium permanganate soaking 20 minutes, or soaked with 10% trisodium phosphate solution for 20 minutes, rinse dry seeding.
