为减少降雨对火龙果产量造成的损失,探索红肉型火龙果雨季授粉技术,比较了不同降雨类型气候条件下,套袋授粉和自然授粉对火龙果产量和品质的影响.结果表明,与自然授粉相比,红肉型火龙果雨季套袋授粉后,座果率提高18.89％～51.67％,平均单果重提高181.79～201.77 g,增产23006.55～27073.95 kg/hm2,为自然授粉处理的2.63～4.19倍;套袋授粉还促进了火龙果的果实发育,增加了一、二级商品果比率,每公顷比对照净增收18.92～20.62万元,增幅达240.7 ％～433.2％,大幅提升了火龙果种植效益,同时对火龙果的内在品质无影响.雨季套袋授粉在生产上是简便、有效、经济、可操作性强的一项技术措施.%In order to reduce yield losses because of rainfall, pollination techniques of pitaya with red pericarprnand flesh in rainy season was explored. The effects of different pollination treatments on the yield and quality ofrnpitaya were clarified in different types of rainfall climatic conditions. Compared with natural pollination, pollinationrnwith bagging treatment increased fruit-set rate of 18.89%~51.67%, the average weight of 181.79~201.77 g andrnyield 23 006.55-27 073.95 kg/hm2. Pollination with bagging not only promoted pitaya development but also madernhigher percentage of commercial fruit and yield as well as economic benefits. The net income over the CK wasrn189 200-206 200 Yuan/hm2, an increase rate of 240.7%~433.2%. The bagging pollination technique of pitaya withrnred pericarp and flesh in rainy season is simple, high efficiency and operable.
