哀牢山壳斗科三种蜜源植物资源的初步研究

壳斗科植物具有丰富花蜜和花粉.2007年4～7月,对云南哀牢山中山湿性常绿阔叶林壳斗科蜜源植物开发利用的潜力进行了初步研究.在该季节,中华蜜蜂可利用的壳斗科植物主要有木果石栎、景东石栎和腾冲栲.3种植物的花期均为50天左右.放置在原始森林林缘蜂群的取蜜量明显高于放置在原始森林内和附近次生林的蜂群.一群放置在林缘、群势为5标准框的中华蜜蜂蜂群,一个花期可以取蜂蜜约5 kg.

Preliminary Study on Three Honey Plant Species of Fagaceae in Ailaoshan

Some plants of Fagaceae provide lots of honey and pollen for honey bees. In the study, we conducted a priminary study on the potential of these plants for Chinese honeybees (Apis cerana) in the midland of Ailaoshan evergreen broad-leave forest from April through July 2007. During the period, three plant species of Fagaceae, including Lithocarpus xylocaspus, Lithocarpus chintungenfis and Castanopsis wattii, are exploited by the bees. These species flower synchronically and last about 50 days. The honey harvest is significantly higher from the colonies at the forest edge than from the colonies within the forest and in neighboring secondary forest. A 5-frame colony at the forest edge can product about 5 kg honey during the flowering period.
