椴树是我国主要蜜源之一,大面积分布在东北,泌蜜量丰富蜜质好,然而年产量极不稳定,给蜂农放蜂造成难以计划的困难。为了逐步攻克这一难题,我们对吉林省敦化地区椴树开花泌蜜与气候条件之关系进行了观测试验,计算分析,得出该地区1985、1986年椴蜜低产歉收主要因不同类型的气候异常所致。这一工作为椴树泌蜜产量的预报研究
Linden tree is one of the main honey sources in our country. It is widely distributed in the northeast of China. It is rich in honey, but its annual output is extremely unstable, making it difficult for beekeepers to plan beeing. In order to gradually overcome this problem, we conducted an experimental study on the relationship between the flowering and flowering of the linden tree and the climatic conditions in Dunhua, Jilin Province. The results show that the low yield of linden honey in 1985 and 1986 in this area is mainly caused by different types of climate anomalies Due. This work is forecasting the yield of lime tree
