【摘要】 本文研究了长白山区松茸发生地的土壤状况．研究认为松茸的发生与土壤的地理环境、机械组成、土层构造、养分含量及土壤酸碱度关系密切，山地陡峭、质地粗糙、养分贫瘠、腐殖质层薄、PH偏低是长白山区松茸发生地的土壤特征。更多还原

【Abstract】 The soil state of pine mushroom (Tricholoma Mats utake) occuring area i n Changbai Mountain is stUdied in the paper. It’s concluded that Tricholoma Matsutak e Occuring has a close bearing on the geographical conditions, mechanical composition,structural gradation, content of fertility and acidity or alralinity of soil. They are the soil features of pine mushroom (Tricholoma Mats utake) Occuring area in Changbai Mountain that slopes are cliffy, mechanical composition is rough, fertility is poor,humus horizon is thin and PH is on the low side.更多还原
