大兴安岭北部地区兴安落叶松外生菌根类型的初步研究

STUDY ON ECTOMYCORRHIZAL TYPE OF Larix gmeliniI GMELINII IN NORTH DAXING'ANLING MOUNTAIN

经过2年来对大兴安岭北部地区兴安落叶松外生菌根的调查研究,采用形态和解剖结构特征的综合观察分类方法,初步划分出了15种不同菌根类型。并对不同森林采伐方式下的菌根类型进行了统计,其中原始林中外生菌根类型为11种,皆伐林为9种,渐伐林为6种,表明不同森林采伐方式对菌根共生类型有明显的影响作用。

Systematic investigation was made on ectomycorrhiza in the woods of Larix gmelinii in north Daxing＇anling area in the past two years. According to morphological and anatomical characters, 15 ectomycorrhizal types were described. And the influence of different logging ways on the changes of ectomycorrhizal types were analyzed, 11 ectomycorrhizal types were found in original forest, 9 ectomycorrhizal types were found in clear cutting forest, 6 ectomyeorrhizal types were found in successive cutting forest. The results showed that the different logging ways played a significant role in ectomycorrhiza symbiosis types.
