寒地果树凹唇壁蜂授粉及对坐果的影响1）

摘要

Release Osmia before apple blossoms ,recycle of bee tubes after flowering ,and the hive ,bees , Osmia pollination situation investigation .Results show that the Osmia activity time is 7-16 points at cold region ,paper tube recovery rate is lower than the reed pipe recovery ,fruit-set rate highly natural pollina-tion fruit trees ,fruit seeds ,fruit weight and fruit shape index increased significantly .%在苹果开花前释放壁蜂，花后对蜂管进行回收，并对蜂箱、蜂管、壁蜂授粉情况进行调查。结果表明：在寒地壁蜂的活动时间为7～16点，纸管回收率低于芦苇管回收率，坐果率高于自然授粉果树，果实种子数、单果重和果型指数明显增加。
