从土壤化学性质的角度对长春市人民大街左右两侧油松生长不良状况进行调查,调查土壤剖面深度70cm。调查结果显示:油松生长状况与土壤有机质(OM)含量呈显著正相关关系。30 cm以下土层,油松生长状况与土壤有机质(OM)含量呈极显著正相关关系。从土壤养分方面而言,油松生长状况最直接影响因素极可能是土壤耕层以下有机质匮乏引起。土壤偏碱性对油松生长有一定影响。

This paper conducts the bad growth situation of Pinus Tabulaeformis along People Street greenbelts of Changchun from the perspective of soil chemical properties.The soil profile depth is 70cm.The results show that there is a significant positive correlation between Pinus Tabulaeformis growth and soil organic matter content,and there is an extreme significant positive correlation below 30cm soil layer.As far as soil nutrient is concerned,the most direct factors that influence Pinus Tabulaeformis growth may be the scarcity of soil organic matter content.Soil pH alkaline has effects on Pinus Tabulaeformis growth.
