| 摘 要： | 探讨了施用不同水平的尿素和磷酸二氢钾对红蓝石蒜Lycoris haywardii当季和翌年生长季叶片生长状况及鳞茎生物量的影响,并对叶量进行主观评价.结果表明:高用量施用尿素对红蓝石蒜叶片数量、叶片长度、芽数、鳞茎数量以及鳞茎生物量等均产生了显著的负面影响；红蓝石蒜对磷酸二氢钾的耐受性良好,高用量施用对当年生叶片数量有显著的促进作用,但翌年影响不明显;叶片数量与鳞茎生物量呈线性相关关系,与主观评价定性结果相一致,可以利用主观评价法估计鳞茎的生物量动态变化,实时掌握施肥对鳞茎产量的影响效果.

| Abstract: | To study the effects of carbamide and KH2PO4 as fertilizer on leaf growth and bulb biomass of Lycoris haywardii over two successive growing seasons,an experiment with a two-factor design of four different carbamide and KH2PO4 application levels（carbamide at 0,0.5,1.0 and 1.5 kg·m-2;KH2PO4 at 0,0.35,0.70 and 1.05 kg·m-2） as a topdressing fertilizer and three repetitions was established.Data were analyzed with SSPS16.0.Results showed that carbamide applications（0.5 kg·m-2） had a significant（P0.05） negative effect on leaf number,sprout number,bulb number and bulb biomass in the next growing season,and leaf length in the following growing season.The KH2PO4 treatment at 0.35 kg·m-2 in the following growing season significantly increased the leaf count（P0.05）.Leaf quantity was linearly and positively related to the bulb biomass（linear regression;r=0.941,P=0.000） and was similar to qualitative results from subjective evaluations.So,subjective evaluation could be used to estimate live-weight trends for bulb biomass and to evaluate growth effects of L.haywardii with fertilization. |
