| 摘 要： | 根据水仙的生理学和生态学特性,设计不同日照时数试验,系统研究不同日照时数对水仙的植株高度、叶片数、花蕾数、开花数等指标的影响。结果表明：在适宜的温度和水分条件下,0 h处理下水仙植株最高（32.5 cm）,但是由于缺少光照,植株出现黄化现象。叶片数最多的处理为2 h（32.3片）,但由于日照时数少,光合积累少,叶片较小。综合分析,以10 h光照处理水仙观赏品质最好,其叶片数、花蕾数、开花数分别为：30.33片、22.3朵/株、17.33朵/株,开花率为77.58%。该研究为春季期间水仙室内管理提供参考。

| Abstract: | According to the physiological and the ecological characteristic of the Narcissus, the experimentation with different day length was carried out to test the effect of Photoperiod on the plant height, the number of leaves, buds and flowers of Narcissus. The results showed that under the optimized conditions of temperature and water, in the 0 h day length treatment, the plant height of the Narcissus was the highest than that of others, which was 32.5 cm. But there was a lack of sunlight, the etiolating phenom... |
