【摘要】 鹅掌楸[Lriodendron chinense (Hemsl.)Sarg.]是我国二级珍稀濒危重点保护植物,存在着从它的分布北界大巴山引种到西安地区能否适应的问题。本文通过对其叶片的蒸腾作用、光合作用、水分状态,抗热能力和抗脱水能力等生理特性的试验研究,以及植株在栽培中的实际表现,结合与对照植物的比较研究,得知该树种能够忍耐轻度的干旱和高温,能安全越冬,适宜于较温暖和较湿润的环境.只要适当浇水和施肥,它完全适应西安地区的气候条件。更多还原

【Abstract】 Liriodendron chinense is the rare and threathend important protected plant of second degree in our country. There is a problem of introduction adaptation from it’s north frontier-Dabashan Mountain to Xi’an area. Through physiological speciality experiments such as transpiration, photosynthetic, water condition, hardness to hot and dewatering, growth apperance and comparison with contrast plants, this article shows that the species can endure slight drought and hot, pass winter well, adapt to rarely warm and moisture environment. As long as watering and fertilizing properly, this species can adapt to the climate condition of Xi’an area.更多还原
