摘　　要：采用平茬技术在天然环境中进行双因素试验的结果表明,在落叶松疏林地和灌木沼泽2种环境中平茬复壮技术均有效解决了天然笃斯越橘的种群退化问题,与对照相比,试验组的1年生枝数量、2年生枝数量及1年枝与2年枝比例分别提高了139.93%、-6.73%及156.63%,密度提高了17.71%。To achieve Vaccinium uliginosum artificial tending by use stumping technology for two-factor test in the natural environment. The results showed that stubble rejuvenation technology can effectively solve the problem of the degradation of natural populations of Vaccinium uliginosum,and are effective in the two kinds of larch and wetland environments. Compared with the control, ＂the number of branches of 1 years old＂ and ＂Number of branches 2 years old＂ and ＂the ratio between them＂, the experimental group were increased by 139.93% and 156.63% and-6.73%, density improved 17.71%.
