水培变叶木、发财树和金钱树的养分配比研究

Research on nutrient ratio of hydroponic Codiaeum variegatum,Pachira macrocarpa,and Zamioculcas zamiifolia

以海南典型的热带花卉变叶木Codiaeum variegatum,发财树(瓜栗)Pachira macrocarpa和金钱树Zamioculcas za-miifolia为研究对象,通过一系列的水培试验,并利用有关的统计软件分析,以期达到各品种最佳的养分配比。结果表明,在海南的热带气候条件下,变叶木水培的氮磷钾最适浓度配比为7:1:4,发财树的最适配比为2:3:11,金钱树的最适配比为3:2:8。

Chasing the typical tropical flowers,Codiaeum variegatum,Pachira maerocarpa,and Zamioculcas zamiifolia as the research object, through a series of water cultivating experiment, and using relevant statistical analysis software,we hope to achieve the best possible nutrient ratios of the above varieties. The results showed that under the typical tropical climate in Hainan, the optimum NPK ratio of hydroponic Codiaeum variegatum is 7：1：4;the optimum NPK ratio of hydroponic Pachira macrocarpa is 2：3：11;the optimum NPK ratio of hydroponic Zamioculcas zamiffolia is 3：2：8.
