【摘要】 通过对内蒙古大兴安岭林区松口蘑资源调查，初步掌握其生长环境和分布规律。调查结果表明：松口蘑主要分布在阿龙山林业局、满归林业局、永安山林业局，适合生长在海拔600～1000m的樟子松与落叶松混交林下，以山地阳坡和半阳坡缓坡中下部或上部平缓处为主，以东南坡、西南坡分布较多，林分郁闭度以0.2～0.3最佳。樟子松林龄一般在60a以上，树木胸径30cm以上，菌株个体分布在树木周围5m范围内，地被植物覆盖度小于50%，气温一般以10～20℃为宜，湿度不低于30%。更多还原

【Abstract】 This study conducted a survey on the resources of Tricholoma matsutake in the Greater Khingan forest area of Inner Mongolia, preliminarily grasping its growth environment and distribution patterns. The survey results indicate that the Tricholoma matsutake is mainly distributed in the Alongshan, Mangui, and Yong’an Mountain Forest Bureau areas, thriving in larch and deciduous mixed forests at altitudes of 600 to 1000 meters, predominantly on the gentle middle to lower parts or the upper gentle parts of south and southwest slopes, with the best canopy density for growth being between 0.2 and 0.3. The larch forest age is generally over 60 years, with tree diameters at breast height of more than 30 cm. The truffle individuals are found within a 5-meter radius around the trees, with a ground cover plant coverage of less than 50 %, and the optimal temperature range for growth is 10 to 20 ℃, with humidity not lower than 30 %.更多还原
