伊春地区野生蓝靛果资源及群落特征的研究

Research on Resource and Community Characteristics of Wild Lonicera edulis in Yichun Region

为揭示野生蓝靛果在小兴安岭地区的资源分布规律,采用野外调查与室内试验相结合的方法对伊春地区野生蓝靛果资源分布及群落特征进行研究。结果表明:在该地区野生蓝靛果主要分布于海拔300～390m的沟台、缓坡和陡坡,坡向以南坡为主,生长在地势平坦、阳坡、土壤肥沃、pH近中性或偏酸的环境中;以毛果苔草+小叶樟-丛桦-红松群落和苔草-毛赤杨+兴安落叶松群落为主。因此,伊春地区发展蓝靛果产业应因地制宜,利用林缘、低洼地、沟台等地进行人工栽培。

In order to reveal the resource distribution regular of wild Lonicera edulis in Xiaoxinganling region,the field investigation and laboratory test were used to study the resources distribution and community characteristics of wild Lonicera edulis in Yichun region.The results showed that region wild Lonicera edulis were mainly distributed at ditch,gentle slope and steep slope between elevation 300～390m.And direction of slope is mainly south slope.They grew in the environment of flat,sunny,fertile,pH value nearly neutral or slant acerbity.There were two communities that were Carex lasiocapa＋Calamagrostis angustifolia-Betula fruticosa Pallas-Pinus koraiensis and Carex-Alnus sibirica＋Larix gmelinii kuzenneva.Therefore,developing Lonicera edulis industry in Yichun region should adjust measures to local conditions,utilize forest margins,low-lying areas and ditches for artificial cultivation.
