| 摘 要： | 观察北方日光温室环境条件下,番荔枝的开花结果特性;研究人工授粉最佳时期和授粉技术,为日光温室番荔枝栽培提供技术支撑.结果表明:在北方日光温室环境条件下,番荔枝自然开花集中时间为5月下旬到7月上旬,6月9～23日,是番荔枝开花数量多并且坐果率较高的时期,生产中可充分利用这一时期的人工授粉提高坐果量.但是,从单果重和品质等指标分析,5月26日到6月8日之间授粉坐果的番荔枝果实更具有商品价值,其次是6月9～23日期间授粉的果实,而6月24日之后的果实单果重和品质显著降低.因此,生产中需要尽量保证前期花朵的成功授粉与结果.八P.番荔枝花药主要集中在傍晚6:00～8:00裂开,生产中,可以在早6:00～8:00选择半张开花朵作为花粉源,也可以在晚6:00～8:00选择完全张开的花朵作为花粉源进行授粉.

| Abstract: | We observed the flowering and fruiting process of sweetsop(Annona squamosa L.),to found the best time for artificial pollination in Beijing greenhouses.In our results,the sweetsop flowering time was during the last third of May to the early July in Beijing greenhouses.6.9 to 6.23 was the very stage which had more flowers and high set rate.We could use this period for artificial pollination to enhance the output.But in the quality analysis,the fruits pollinated during 5.26 to 6.8 were more valuable of mercha... |
