摘　　要：通过对山西省西南部乡宁县胡家岭的翅果油树开花期观察记录8天,并对获取的基本数据分析,结果表明:蜂类是翅果油树的主要传粉者,甲虫类次之,而蝶类是一种不稳定的传粉者.翅果油树花泌蜜丰富,能吸引大量昆虫为其传粉.翅果油树在异株异花传粉、同株异花传粉和自然授粉后,其结实率分别为69.2%、60.0%和17.93%.翅果油树不存在无融合生殖的特性,且自花授粉结实率很低只有26.7%.The base data of the community of Elaeagnus mollis Diels are analysed from the continous observation about eight days in Jujialing of Xiangning lied in the South-western of Shanxi province.The result indicates that the bees are the main pollinators,beetles are second and butterflies were only fluctuating vectors.Flowers of this taxon are rich of nectariferous.Flowers attracted a lot of insects mainly by pollen.The rate of seed Artificial xenogamy,Artificial geitonogamy and Natural pollination is 69.2%,60.0% and 17.93%,respectively but it can not propagate without connection.The rate of seed Natural pollination is 26.7%.
