Investigation of Phalaenopsis hybrid growth in bark-media using controlled release fertilizer
2015
Kodama, M. | Watanabe, T. | Numao, T.
Bark chips are currently used to grow Phalaenopsis Hybrid plants instead of sphagnum moss. However, fertilizer management has not been changed and, as in sphagnum media, liquid fertilizer is still being used. This has caused a decrease in the number of inflorescences and, thus, growth retardation has become a problem. In order to improve the fertilization method, it compared liquid fertilizer or controlled release fertilizer to have influence that it was good for the growth of Phalaenopsis Hybrid. Plants grown with controlled release fertilizer showed better growth and flowering than those grown with liquid fertilizer. Phalaenopsis Hybrid plants showed good growth with twelve leaves and ten inflorescences. Furthermore, this method enables efficient fertilizer management as approximately 65% of the given nitrogen content was absorbed.
