摘要
为探究观赏甘薯在水培条件下无机营养及水分吸收特性与生长发育的关系,获得水培观赏甘薯生长的最佳营养配方及浓度,并为其在园林及室内园艺中应用提供理论基础和技术依据。以不同叶色的观赏甘薯为试验材料,采用正交设计的方法对不同营养液条件下观赏甘薯生长情况进行研究。结果表明：观赏甘薯在pH范围为6.5~7.0,EC值范围为2.51~2.66,1/2倍浓度循环水生菜营养液中无机营养吸收、叶绿素及生长生物量指标与其他几种营养液条件相比均有显著差异,生长达到最佳的观赏效果,可为居室及园林带来生机。
In this paper ornamental sweetpotato with different leaf was used as the main test material to study the relationship between inorganic nutrients and the growth of hydroponic culture. It has discussed the best experiment nutrition, all the researches may provide some academic and technical supports for ornamental sweetpotato when it applies in landscape and indoor garden. The resuhs were as follows： the content of CKI and the growth had significant differences with others by treating with 1/2 times lettuce circulating experiment nutrition, kept the pH 6.5-7.0 and EC 2.51-2.66. in that condition. It can achieve the best viewing and bring life to the garden
