Effects of Controlled-release Fertilizer on Leaf Area, Stalk Length and Vase Life on Cut-flower of on Anthurium andreanum Cultivation
Wang M. C., Y. T. Chang and A. H. Yang
In Taiwan, the most popular fertilizer of Anthurium andreasnum cultivations is a controlled-release fertilizer called Hi-control No. 1. In this study, we evaluated a controlled-release fertilizer (CRF) which had been developed by Tainan District Agricultural Research and Extension Station. The new CRF was applied in greenhouse-grown anthurium to compare with Hi-control No. 1 and Osmocote. The EC value, plant growth rate and yields of cut flowers were surveyed. The result indicated the releases of fertilizers were affected by different seasons, plant growth rates and the degradation of medium. During the rapid growth stage of leaves, growth rates of commercial fertilizers were better than the new CRF. The production of cut flowers and vase lives did not differ among all treatments. The earlier release rate of new CRF is still the main issue. As the higher EC value of CRF made by TDARES is improved, the new CRF may be applied in floriculture.
What is already known on this subject?
The popular fertilizers of Anthurium andreasnum cultivations in Taiwan are commercial controlled-release fertilizers called Hi-control and Osmocote. By far, Hi-control No. 1 (N-P2O5-K2O=14-12-14) and Osmocote (14-14-14) are much more applied among Anthurium growers.
What are the new findings?
The new controlled-release fertilizer (CRF) could apply in greenhouse-grown Anthurium cultivars.
What is the expected impact on this field?
The new CRF may be applied in Taiwan floriculture, and could substitute the use of commercial fertilizers.
