紫椴(Tilia amurensis Rupr)为我国主要蜜源植物之一。主要分布于东北的小兴安岭和长白山林区。紫椴属椴树科落叶乔木,花期6月底至7月下旬。椴树蜜质优良,为主要出口蜜种。但紫椴的泌蜜量受气候、土肥、生理生长状态等诸因素影响较大,年际间产量很不稳定。如能在椴树开花前2～3个月预测出当年泌蜜情况,将对养蜂场全年生产安排,夺取高产、稳产创造有利条件。本文主要从生理学,气象学角度入手,探讨椴树的泌蜜规律,从而为掌握预测预报其泌蜜量大小的方法提供科学依据。
Tilia amurensis Rupr is one of the main nectar plants in China. Mainly distributed in the northeast Xiaoxing’anling and Changbai Mountain forest. Tilia Tiliaceae deciduous tree, the flowering end of June to late July. Linden tree honey quality, as the main export honey species. However, the amount of secretion of Tilia amurensis by the climate, soil fertility, physiological growth status and other factors greater impact, annual production is very unstable. If the lime trees 2 to 3 months before flowering predicted the situation that year, the honey will be the annual production of beekeeping arrangements, to seize high yield and stable production to create favorable conditions. This article mainly from the physiology, meteorology point of view, to explore the law of the secretion of honey lime, so as to master the method of predicting the amount of nectar secretion provide a scientific basis.
