笃斯越橘生物与生态学特性调查及主要经营技术

黑龙江省大兴安岭笃斯越橘资源丰富，生长条件得天独厚，但受自然因素等影响，产量不高不稳。在大兴安岭阿木尔林业局红旗林场设置试验地进行笃斯越橘的生物与生态学特性调查以及经营技术试验。调查结果显示了其形态特征、不同分布类型的种群植株特征、果实特征等生物与生态特性。试验结果表明，推广应用笃斯越橘资源的平茬复壮、疏灌透光等经营技术，可以提高笃斯越橘产量、扩大种群分布面积，可有效保护笃斯越橘资源与恢复野生种群。

Survey on Biological and Ecological Characteristics of Vaccinium uliginosum and Key Management Techniques

Daxing＇anling, Heilongjiang Province is rich in Vaccinium uliginosum resources for unique growing conditions, but impacted by natural factors, the yield of production is lower and instable. The experimental spot for biological and ecological characteristics survey and management techniques of Vac- cinium uliginosum was set up in Daxinanling Amuer Hongqi forest farm, Heilongjiang Province. The re- sults demonstrated its morphological characteristics, plants characteristics with different distribution, fruit characteristics and other biological and ecological characteristics. The results also showed that by promo- ting the management techniques of stubble rejuvenation and shrub transparency could improve the yield of Vaccinium uliginosum, expand population distribution area, and effectively protect Vaccinium uliginosum resources and restore wild populations.
