Abstract：Curcuma alismatifolia was used as the test material to study the effects of controlled release fertilizers with different ratios of N-P-K and the common compound fertilizers on the growth of C. alismatifolia by measuring its plant height, stem thickness, leaf length, flowering rate and chlorophyll content.The results showed that the application of controlled-release fertilizer was more beneficial to increase the leaf length and the chlorophyll content of C. alismatifolia than compound fertilizer under the same amount and composition of fertilizer, and the best effect on the growth of C. alismatifolia was achieved on the N-K controlled-release fertilizer. Meanwhile, the application of controlled release fertilizer was more beneficial to the flowering of C. alismatifolia. The flowering rate of P-K controlled-release fertilizer was the highest, which can improve the ornamental value of C. alismatifolia. Consequently controlled release fertilizer was more conducive to the growth of C. alismatifolia.
