中文摘要 | 非洲堇在臺灣是具發展力的盆花植物,惟其根系對通氣的要求甚高,易發生根腐。土壤使用於盆栽時通氣不良。本研究嘗試發展一套水分管理來解決以土壤為栽培介質,盆栽非洲堇的通氣問題。設計乾土盤水分管理法,並以低張力的水分張力計,測量盆栽介質過濕問題。乾土盤的設計能改善盆栽的通氣性,由低張力的水分張力計的張力變化,或由體積含水量的減少趨勢可知排水的效果。乾土盤水分管理法,能排走盆栽介質中大孔隙的水,增加通氣。此一方法對通氣較差的介質特別有效,可使栽培介質的選用更具彈性。 |
英文摘要 | African violet is a popular houseplant in developed countries. The beautiful plant requires intensive care for almost year-around flowering. It demands highly aerated growth medium to prevent root rot. A dry-soil pan method, a pan of dry soil was put beneath the pot was designed to drain the excess water after irrigation. The drainable air porosity was effectively increase to prevent root rot. |
