天南星科、龙舌兰科、棕榈科观叶植物在闽中地区的引种适应性

对天南星科、龙舌兰科、棕榈科观叶植物的基本生态习性研究表明,三科观叶植物的适合生长温度多在18~28℃之间,当温度低于10℃或者高于35℃时,大多数植物出现寒害或热害,生长停滞。天南星科和龙舌兰科植物长势较好的遮光度分别为75%和50%左右;而棕榈科植物多数可在全光条件下正常生长。不同科植物之间对土壤水分的需求差异较大,天南星科植物要求最高(大于80%),其次是龙舌兰科,为70%,棕榈科植物要求较低,为55%;空气湿度85%~90%最有利于这几类观叶植物生长。

Adaptability of Introduced Foliage Plants of Araceae, Agavaceae and Palmaceae in the Central Part of Fujian Province

The basic ecological characteristics and introduced adaptability of Araceae, Agavaceae and Palmaceae in the central part of Fujian Province were studied.The results showed that the suitable growth temperature for most of the plants was 18~28℃.When the temperature was lower than 10℃ or higher than 35℃, most plants would stop growing or be injured.The shade density of 75% was suitable for Araceae and 50% for Agavaceae.Palmaceae could grow normally under full exposure.The optimum soil moisture content for the growth of Araceae was higher than 80%, Agavaceae higher than 70%, and Palmaceae higher than 55%.When the humidity of the air was 80%~90%, it gave the best condition for the growth of these foliage plants.
