三系配套辣椒制种壁蜂授粉技术应用初探

Preliminary Studies on Application of Wall Bee Pollination Technology in Threeline Seed Production System of Pepper

2016~2017年以人工授粉作为对照,进行了三系配套辣椒制种壁蜂授粉试验。结果表明:三系配套辣椒制种壁蜂授粉时父母本的最佳配比为1∶3,父本、母本相间栽培。壁蜂在温室中的适应性较好,辣椒坐果率、单株结果数、种子千粒重及制种产量均高于人工授粉,并大幅度降低了制种成本,每个温室成本降低86.7%。壁蜂授粉技术的应用在三系辣椒制种中具有可行性,且制种效果好。

Taking artificial pollination as the contrast,an experiment of wall bee pollination with threeline seed production system of pepper was conducted.The results showed that the optimum proportion of male and female parents is 1∶3 with interval cultivation.Wall bee had good adaptability in greenhouse.The fruit setting rate,fruit number of single plant,1 000-grain weight and yield of seed production by wall bee pollination were higher than that by artificial pollination.Thus,the cost of seed production was reduced by a large margin.The cost of each greenhouse was reduced by 86.7%.The application of wall bee pollination in three-line seed production system of pepper is feasible,and the effect is good.
