【摘要】 为了提高水培观赏植物的成活率和观赏价值,以白掌、太阳神等2种观赏植物为材料,进行不同营养液浓度对水培观赏植物的影响研究。结果表明,随着营养液浓度的降低,水培观赏植物的新生叶数和新生根数出现了先增多后降低的变化规律,1/2园试标准营养液浓度最适合白掌的生长,其浓度为0.50~0.60 g/L;1/4园试标准营养液浓度最适合太阳神的生长,其浓度为0.25~0.30 g/L。说明不同植物适宜的营养液配方是不同的。

【Abstract】 In order to improve the survival rate and ornamental value of ornamental plants in water culture,two ornamental plants(Spathi phyllum spp.and Cordyline terminalis) were used as research materials and the effects of different nutrition concentrations were studied.Results showed that with the reduction of nutrition concentration,new leaves and roots of the ornamental plants increased firstly and then decreased,the concentration of nutrient solution for 1 / 2 garden test standards was the most suitable concentration(0.50~0.60 g / L) for the growth of the Spathi phyllum spp.,the concentration of nutrient solution for 1 / 4 garden test standards was the most suitable concentration(0.25~0.30 g / L) for the growth of the Cordyline terminalis.Therefore,different plants needed different formula of nutrient solution.
