观赏植物水培根系诱导技术与经济效益分析

Induction Technology of Root and Analysis on Efficiency of Economic on Ornamental Plants in the Water Culture

以熊掌木、龟背竹、春芋、海芋为材料在养鱼、光照、黑暗条件下,以虎皮兰为材料在增氧、静止条件下,以金琥为材料在黑暗、光照条件下进行根系诱导比较研究,以提高观赏植物的水培成活率和观赏价值。结果表明:不同植物长根速度有很大区别,该试验发根速度快慢排名为:海芋>龟背竹>熊掌木>春羽>金琥>虎皮兰。增氧更适合虎皮兰、海芋,光照对熊掌木、金琥来说较适宜,黑暗更适合海芋,养鱼适合春羽、龟背竹。最后进行了水培植物投资经济效益分析。

To improve water survival and ornamental value at ornamental plants under water culture, six species of ornamental plants was comparatively studied, Fatshedera lizei ,Monster deliciosa , Philodendron selloum , Alocasia macrorrhiza （Linn.） Schott were planted under the pisculture, the illumination, the dark condition, Sansevieria trifasciata were planted under increases the oxygen and static condition, Echinocactus grusonii were planted under darkness and the illumination condition. The results showed that the different plants root--speed vastly different, root--peeds rankings.Alo- casia macrorrhiza （L inn. ） Schott〉Monster deliciosa 〉 Fatshedera lizei 〉 Philodendron selloum 〉 Echinocactus grusonii 〉Sansevieria tri fasciata. Increased oxygen more appropriate for Sansevieria tri fasciata and Alocasia macrorrhiza （Linn.） Schott, the illumination appropriate for Fatshedera lizei and Echinocactus grusonii ,the pisculture appropriate for Fatshedera lizei and Monster deliciosa. Finally, the efficiency of economic had analysis.
