摘要/Abstract

摘要：

为给姜荷花的标准化栽培生产提供一定的参考,以盆栽姜荷花为试验材料,采用不同温度、光周期对姜荷花进行研究。结果表明,25℃是姜荷花生长较适温度,高温对其萌发有一定的促进作用,过高或过低的温度都会导致其不开花;不同温度影响下,姜荷花萌发率、分蘖数及开花数具有一定的相关性,对姜荷花pH、EC的影响较小。光照时长延长至14~16 h时,可打破姜荷花休眠,实现周年生产;姜荷花分蘖数随光照时长的增加而显著提升,对开花时间、开花数未见显著影响;姜荷花各指标之间未呈现显著相关性,对姜荷花pH、EC有一定影响。

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
