乌苏地区,冬季严寒,蜜蜂越冬期长(十二月至翌年四月),新引进蜂种不能适应,加之管理技术不善,每年越冬死亡率大,成为发展养蜂业的主要障碍.我场一九六一年入室蜂146群,死亡率达78%.一九六二年,认真总结了七年来失败的教训,改进了秋季及越冬期的管理技术,一九六三年情况大为好转,入室85群,出室83群,死亡仅2.3%,初步摸索到一些经验. In the Wusu area, winter was cold and bees overwinter for a long period of time (December to April of the following year). The newly introduced bee species can not be accommodated. In addition, poor management techniques and annual overwintering mortality rate have become major obstacles in the development of beekeeping industry. In 1986, the number of bees was 146 and the death rate was 78%. In 1962, the lessons learned in seven years of failure and the management techniques in autumn and wintering were improved. The situation was much improved in 1963 , Entered the group of 85, out of room 83 group, only 2.3% death, preliminary exploration to some experience.
