在1989年至1993年间,科研小组用无土栽培方法试验栽培了12科60种室内花卉,结果发现除少数品种在液培环境下度夏、过冬困难外,许多种如:绿萝、龟背竹、吊兰、木麒麟、玉晴蜓、花叶豆瓣绿、虎耳、鸭趾草等能适应改变了的环境,长势良好,具有推广价值。试验还从筛选营养液方面着手,选用四种不同配方进行栽培比较。结果表明:每种花卉的适应性不同广谱的营养液具有浓度小,氮素含量较低,相对的Ca~(2+)、Mg~(2+)、SO_4~(2-)等较丰富的特点。
From 1989 to 1993, the research team cultivated 12 indoor 60 species of indoor flowers by soilless cultivation test. The results showed that except for a few cultivars which spend summer and wintering in liquid culture environment, many species such as green dill, , Chlorophytum, wood unicorn, jade dragonfly, petunia, Tiger ear, duck toes and other adapt to the changed environment, good growth, with the promotion of value. The experiment also started from the screening of nutrient solution, using four different formulations for comparison. The results showed that the adaptability of each flower varied widely among different nutrient solutions with low concentration of nitrogen and relatively abundant Ca 2+, Mg 2+, SO 4 2- specialty.
