摘要

為探討韭菜、龍鬚菜、蕹菜及紅鳳菜等四種宿根性蔬菜在不同淹水時間處理對其產量之影響，以及在颱風豪雨過後進行不同施肥處理對其產量之影響，分別於2004年及2005年在花蓮縣及宜蘭縣進行試驗。經人工淹水處理後調查四種宿根性蔬菜之產量，試驗結果顯示以蕹菜之耐淹性最佳，在生育盛期經淹水48小時後之產量比不淹水之對照區增產27.1%，而紅鳳菜最不耐淹水，其次依序為韭菜及龍鬚菜，分別比對照區減產59.2%、26.0%及25.5%。四種宿根性蔬菜在颱風豪雨過後，分別經不同施肥處理後調查其產量，龍鬚菜以葉面噴施台肥1號即溶複肥（氮：磷酐：氧化鉀=26：13：13%）150倍液之產量最高，韭菜、蕹菜及紅鳳菜則均以土壤施用化學肥料（氮：氧化鉀=84：24公斤／公頃）之產量最佳，此結果將可提供花蓮地區葉菜類蔬菜栽培者之參考。

The objective of this study is to investigate the effects of different waterlogging periods and fertilization for ratooning vegetable after typhoon disaster. The studies were conducted from May 2004 to Sep. 2005 at Haulien and Ilan county. The results indicated that water convolvulus was more tolerant to waterlogging than chayote, Chinese leek and Gynura bicolor. The yield of water convolvulus which was treated with waterlogging 48 hours, during prolific growth stage, is higher than the control by 27.1%. Chayote shoot got higher yield when treated with foliage dressing of diluted (150x) TFC No. 1 instant fertilizer (N: P2O5: K2O = 26: 13: 13%) after typhoon disaster. On the contrary, Chinese leek, water convolvulus and Gynura bicolor got higher yield with top dressing with chemical fertilizer nitrogen : potassium oxide = 84 : 24 kg/ha.
