摘要

利用砂/杉木屑混合無土介質。拌三分之一～三分之二體積台北市下水道脫水汚泥，栽值矮牽牛'White Cascade'已具要球之成苗及細葉萬菊'Perite Yellow'小苗，再追施硝酸鉀或完全肥料，可生産優良品質之盆花。汚泥用量以佔三分之一體積爲宜。拌有汚泥介質。矮牽牛葉含氮、磷、鈣、硼、錳、鋅、銅較對照爲多；對細葉萬壽菊，在測試19種元素中，除鉬含量增加外，其它18種元素含量均增高。在所有元素中鋅含量最多，在拌入三分之二體積汚泥者，矮牽牛葉片有黃化現象，認爲與鋅過多有關。

Petunia 'White Cascade' and French marigold 'Petite Yellow' were grown on sand/sawdust (1:1) mix amended with 1/3-2/3 volume of digested sewage sludge and fertilized with complete nutrients or potassium nitrate, The sewage sludge was found to be an effective ingredient and as a low analysis slow releasing fertilizer for potting media for petunia and French marigold when liquid nutrients were applied. Sludge supplied much higher amount of N, P, Ca, B, Mn. Zn, Cu than control in petunia, Sludge also supplied higher amount of most elements that had been tested (19 elements except Mo) than control in French marigold, The chlorosis of petunia would be induced by Zn toxicity when media amended with 2/3 by volume of sewage sludge. However, the French marigold seems can tolorance high content of Zn in tops.
