苹果园花期放蜂李岩（山东省果树研究所泰安２７１０００）苹果除国光等个别品种有自花结实能力外，绝大多数品种自花结实率不足１０％，三倍体品种（乔纳金、北斗等）自花结实率为零；因此苹果在建园时应注意配置授粉树，在授粉树配置不足或花少的年份，只有花期人工授粉...
Apple orchard flowering bee Li Yan (Shandong Institute of Pomology, Taian 271000) In addition to apple and other individual varieties have self-cultivation ability, the vast majority of varieties of less than 10% self-flowering, triploid varieties (Jonathan, Beidou, etc.) self-fertility rate is zero; therefore, Apple should pay attention to the configuration of polluting trees in the park, pollination tree configuration or less spent in the year, only flowering artificial pollination ...
