摘要: 
The primary purposes of this study were to investigate the effect of heavy
fertilization onsoil pH, electrical conductivity (EC), nitrogen phosphorus and
potassium status as well as on thegrowth of Chrysanthemum sp.. The effect of high
EC, resulte

本研究之目的在探討大量施用化舉肥料之下,花卉園土壤電導度(EC)
值、pH值以及氮、磷、鉀之變化及其與花卉生長之關係。並探討土壤尿素水解
?t、磷酸酯?t、固氮?t對高土壤電導度之敏感程度。結果顯示在農戶施肥量0.5
倍、1.5倍、2.0倍之施肥量下,菊花(菊屬,Chrysanthemum sp.)之生長並無顯著差
異。但畦邊表土之EC值可高達6.2mS/cm。pH值則可從7.6降至5.6。在田間調查之
結果則顯示,有些非洲菊(大丁菊屬,Gerbera sp.)花圃表土之EC值已高達
19.6m
