Abstract:

The paper aims to provide certain reference for the standardized cultivation and production of Curcuma alismafotia. The potted C. alismafotia was used as the experimental material, and the effects of different temperatures and different photoperiods were studied. The results showed that 25℃ was the appropriate temperature for the growth of C. alismafotia. High temperature had a certain promoting effect on its germination, but too high or too low temperature would lead to non-flowering. The germination rate, tiller number and flowering number of C. alismafotia under different temperatures had certain correlations, and the temperature had little influence on the pH and EC. When the light duration was extended to 14-16 h, the dormancy of C. alismafotia could be broken and annual production could be realized. The tiller number increased significantly with the increase of light duration, but had no significant effect on flowering time and flowering number; there was no significant correlation among the indexes, and the light duration had a certain influence on EC and pH.

Key words: temperature, photoperiod, Curcuma alismafotia, growth, correlation
