摘要
通过对原生地西伯利亚红松和引种地西伯利亚红松嫁接树不同部位酸碱度值的分析,从生理上探索嫁接树对生态条件的适应机制。结果表明:在各类生态因子中,植物对土壤酸碱度的抗性强弱能够决定引种的成败,而海拔、降水量和积温等环境因子对西伯利亚红松嫁接树的生态适应性的影响不明显。
The pH value of different grafting positions of Pinussibirica planted in native place and introduction area were analyzed.The adaptive mechanism of grafting trees on the ecological condition was explored.Result shows that the strong and weak of resistance for plant to soil pH decides the success or failure of the introduction.Moreo-ver,the effect of environment factors (altitude,precipitation and accumulated temperature)on the ecological adapta-bility of grafted Pinus sibirica is not obvious.
