摘 要:对凹唇壁蜂的人工释放技术和授粉效果进行了研究。结果表明,在樱桃花开前1周左右释放冷藏的蜂茧,并采取人为措施,使得壁蜂破茧高峰与初盛花期尽量吻合。巢箱四周开阔,背风向阳,质量好的巢管营巢率高;距主巢箱越近,封管数量越多。壁蜂授粉座果率与人工授粉差异不显著,而极显著高于自然授粉。壁蜂对同一株树的不同方位访花无选择性。he manmade breeding technique and pollination result of Osmia heudei were studied.The result showed as follows∶ Releasing the refrigerated cocoons about one week before the flowering of cherry,and laking the manmade measure in order to make the adult′s active period coincide with the early period of flowering with the nest box(wide,out of the wind and toward the sun)and the good quality nest tube,the breeding rate was higher.The nearer from the main nest box,the more the numbers of sealing tube.The percentage of fertile fruit pollinized by mason bee did not differ much from artificial pollination,but it was extremely higher than natural pollination.That mason bee visited flowers with no choice in defferent positions of the same tree.
