【摘要】 对引进的 10种棕榈科植物的生态习性的研究结果表明 ,大多数植物的最适生长温度在18～ 2 8℃之间 ,低于 10℃表现生长停滞状态 ,寒害或冻害温度在 8～ - 7℃之间 ,温度达 33℃以上就会出现热害 ,不同种 (品种 )的植物这些指标均存在一定的差异 ,但差异最大的是寒 (冻 )害温度。该科植物对光强度要求不很严格 ,在全光照和一定的荫蔽条件下均能正常生长 ,但后者更为有利 ;不同种植物对土壤含水量的要求差别明显 ,说明抗旱性存在差异。此外 ,文中还对繁殖方法及其在园林绿化上的应用前景进行评述和探讨更多还原

【Abstract】 Ecologic characteristic of ten introduced species of Palmae was studied.The preferrendum for the growth of most plants was between 18 and 28℃.Growth would stopped below 10℃.The temperature of cold injury was about 8℃ to -7℃,While hot injury would appear when temperature got up 33℃.These criticals were varied in different species, but the greatest difference was the temperature of cold injury.The research on illumination indicated that the need for light intensity of Palmae was not very strict.They would grow normally under the condition of full illumination or part shade, but the latter was more beneficial to growth.The need for soil moisture was different in different species.It meant that their drought resistance was different.Besides, methods of propagation and application prospect in garden and afforestation were also described and discussed in this paper.更多还原
