摘　　要：以水仙为试材,研究了不同浓度钾(K+)和光照时数对水仙株高、叶片数、叶片厚度、根长等生物学特征特性及花葶数、花朵数等开花特性的影响。结果表明:光照与K+对水仙花的品质产生一定的影响;室内人工光照3h+0.3%KCl的水养法植株最高;室内人工光照3h+0.5%KCl的水养法的叶片数最多;室内人工光照3h+0.3%KCl水养法叶片厚度最好;室内人工光照3h+0.3%KCl的水养法的根长最长;室内人工光照1h+0.1%KCl和室内人工光照3h+0.3%KCl的花葶数最多;室内人工光照1h+0.5%KCl、室内人工光照3h+0.5%KCl和室内人工光照3h+0.3%KCl的水养法的花朵数最多。Taking Narcissus tazetta L. var. chinensis Roem. as material, the effect of different concentrations of potassium （K＋） and illumination hours on biological characteristics of plant height, leaves number, leaf thickness, root length and blooming of scape number, flower number of Narcissus tazetta L. vat. chinensis Roem. were studied. The results showed that different concentrations of potassium（K＋ ） and illumination hours were influential on qualities of Narcissus tazetta L. var. chinensis Roem.. The plant height of Narcissus tazetta L. var. chinensis Roem. was the highest under indoor artificial light 3 h＋0. 3%KCl of water raised method % leaves number was the most under indoor artificial light 3 h＋ 0. 5%KCl of water raised method % leaves thickness was the best under indoor artificial light 3 h＋0. 3%KCl water raised method % root length was the longest under indoor artificial light 3 h＋0. 3%KC1 of water raised method% scape number was the most under indoor artificial light 1 h ＋ 0. 1% KCl and indoor artificial light 3 h ＋ 0. 3 % KCl of water raised method% flower number was the most under indoor artificial light 1 h ＋ 0. 5 %6 KCl, and 3 h＋ 0. 5 % KCl indoor artificial light and indoor artificial light 3 h-l-0. 3%KC1 of water raised method.
