摘要: 近年来,火龙果种植在湖南省益阳地区发展迅速,但在生产过程中果农对病虫害的认识不足,防治不力,导致商品果产质量逐年下降.为有效控制火龙果病虫害,本文详细介绍了湖南省益阳市火龙果生产上的主要病虫害,并提出了一系列防治措施.结果发现,湖南益阳地区火龙果生产上的主要病害包括溃疡病、茎腐病、黑腐病、炭疽病、黑斑病、茎枯病、基腐病、果腐病、根腐病等;主要虫害包括实蝇、斜纹夜蛾、蜗牛、蚜虫、介壳虫、堆蜡粉蚧等.本文总结了以农业防治、物理防治和生物防治为主,化学防治为辅的火龙果病虫害综合防治技术,以期提高该地区火龙果的产量和品质.Abstract: In recent years, pitaya planting has developed rapidly in Yiyang area, but in the practice of planting and production, farmers have insufficient understanding of controlling diseases and insect pests. Ineffective prevention and control resulted in the decline of pitaya production and quality year by year. In order to effectively control the diseases and insect pests of pitaya fruit, this paper introduced the main diseases and insect pests of pitaya in Yiyang city in detail, and put forward a series of prevention and control measures. The results found that the main diseases of pitaya in Yiyang area are canker, stem rot, black rot, anthrax, black spot, stem blight, base rot, fruit rot, root rot, etc. The main insect pests are Tephritidae, Prodenia litura, Fruticicolidae, aphids, Coccoidea, Nipaecoccus vastalor, etc. In order to improve the yield and quality of pitaya fruit in this area, the integrated pest control techniques were summarized, which were mainly agricultural control, physical control and biological control, supplemented by chemical control.
