摘要
为了提高水培观赏植物的成活率和观赏价值,以风信子、月季、鹅掌柴、金琥、吉祥草、苏铁等6种观赏植物为材料,进行不同营养液浓度和不同营养液配方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“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其生长,其浓度为0.5-0.6 g/L;斯泰纳配方有利于鹅掌柴的生长;山崎配方有利于金琥、吉祥草生长;园试标准配方和山崎配方更有利于苏铁的生长.因此说明,不同植物适宜的营养液配方不同.
In order to improve the survival rate and ornamental value of ornamental plants in water culture,six ornamental plants(Hyacinthus orientalis,Rosa hybrida,Schefflera adorata,Echinicactus grusonii,Reiceckea carnea and Cycas revolute) were taken for research materials and the effects on them of different nutrition concentrations and formulas were studied.Results show that with the reduction of nutrition concentration,new leaves and roots of the ornamental plants increase firstly and then decrease;that the concentration of nutrient solution for 1/2 Garden Test Standards is the most suitable concentration for the growth of ornamental plants,witch turns out to be 0.5~0.6 g/L;that Steiner nutrition formula is conducive to the growth of Schefflera adorata while Yamasaki nutrition formula is conducive to the growth of Echinicactus grusonii and Reiceckea carnea;and that Garden Test Standards and Yamasaki nutrition formula are more conducive to the growth of Cycas revolute.Therefore,different plants suit to different formulas of nutrient solution.
