摘要
研究不同浓度的进口水溶性肥料20-10-20和施肥周期对朱顶红(Hippeastrum hybridum)两个品种‘Blossom Peacock’和‘Apple Blossom’盆栽苗生长的影响。结果表明,朱顶红两个品种盆栽苗生长需要肥料浓度有差异,在合理的电导率(EC)范围内,‘Blossom Peacock’在100 mg/kg肥料处理下,生长基质EC最大为1.16 mS/cm,植株苗期叶片增加数最大,在150 mg/kg肥料处理下,EC最大为1.70 mS/cm,植株苗期生长最大叶长增加量最大,在200 mg/kg肥料处理下,球直径增加量最大;‘Apple Blossom’在150mg/kg肥料处理下,生长基质EC最大为1.67 mS/cm,叶片增加数、最大叶长增加量和球直径增加量最大。施肥周期越长,生长基质EC越低,生长旺盛期7 d施肥一次更有利于朱顶红的生长。
Effects of the imported water-soluble fertilizer 20-10-20 and fertilization period on potted seedling growth of Hippeastrum hybridum were investigated.Results showed that there were differences between fertilizer concentration for different varieties of H.hybridum.When fertilized by 100mg/kg 20-10-20,increase of the leaves number for ＇Blossom Peacock＇ was maximum with electro-conductivity （EC）of growth matrix in maximum of 1.16 milli Siemens per cm.When fertilized by 150 mg/kg 20-10-20,increase of the longest leaf length and by 200mg/kg 20-10-20 the bulb diameter for ＇Blossom Peacock＇ was maximum with （EC）of growth matrix in maximum of 1.70 milli Siemens per cm.Increase of the leaves number,the longest leaf length and the bulb diameter of ＇Apple Blossom＇ was maximum with electro-conductivity in maximum of 1.67 milli Siemens per cm when fertilized by 150 mg/kg 20-10-20.As the fertilization period was longer,the EC value was lower.Fertilized every 7 days during the vigorous growth period was conducive to growth of H.hybridum.
