| 摘 要： | 以矮生一串红"展望"品种为试材,研究了不同氮素施用量对无土栽培一串红生长发育的影响。结果表明:无土条件下,一串红适宜的氮素施用量为:Ca(NO3)2.4H2O 100~130 mg/100g水,可有效增加一串红茎粗、花序长、叶绿素含量、可溶性蛋白质含量及根系活力各指标,促进一串红的生长发育,使植株生长健壮,观赏性提高。

| Abstract: | Different nitrogen fertilizer rates on growth development of soilless culture of Salvia splendens.The results showed that Salvia splendens appropriated nitrogen application rate was: Ca(NO3)2·4H2O 100~ 130 mg/100g H2O,could effectively increase the string of stem diameter,inflorescence length,chlorophyll content,soluble protein content and root activity the indicators,to promote the growth of a string of Salvia splendens,so that robust ornamental plant growth increased. |
