摘要

本研究旨在探討設施青蔥有機栽培施用有機質肥料種類與追肥技術對青蔥產量、品質及土壤肥力之影響。施用蔗渣堆肥、牛糞堆肥、豬糞堆肥、大豆粕及化學肥料結果，缺株率介於5.7%-13.1%、株高介於68.4-72.7 cm、蔥白長度介於14.0-17.3 cm及產量介於20.4-28.4 t ha^(-1)，其中以施用蔗渣堆肥之青蔥其缺株率17.3%-18.2%顯著較高，而其株高64.1-66.0 cm及產量14.1-21.3 t ha^(-1) 均顯著較低。施用蔗渣堆肥、牛糞堆肥及豬糞堆肥均能增加土壤中有機質含量與pH值，但會降低土壤之Bray-1磷含量。‘桃園4號’青蔥種植產量以2次追肥及全量基肥處理較高，其次為對照組施用化肥，施用1次與3次追肥之產量顯著低於其他各堆肥處理。‘桃園3號’青蔥穴盤苗種植產量以對照組施化學肥料處理最高，顯著高於以各種有機質肥料追肥處理，其中以施用3次有機質追肥最低，相對低於其他各種堆肥處理之產量。

The study aimed to develop the type and top dressing method of organic fertilizers for Welsh onion cultivation under facility. The results of different organic fertilizers showed that the transplanting death rate was between 5.7 % and 13.1 %, and the plant height was between 68.4 and 72.7 cm, the stalk length was between 14.0 - 17.3 cm and the yield was between 20.4 - 28.4 tons ha^(-1). The transplanting death rate, plant height and yield were significantly worse with the application of bagasse compost. The application of bagasse compost, cow dung compost and pig manure compost could increase the organic matter content and pH in the soil, and decreased Bray-1 P significantly. First as a field test varieties 'Taoyuan No.4' divisions, the highest yield of the treatment with twice dressing and the full amount of basal fertilizer, followed by chemical fertilizer application, the lowest were the treatment with once and three dressing. 'Taoyuan No.3' plug seedlings test results, the highest yield was found in treatment of chemical fertilizer application, and significantly higher than other organic fertilizer application. Three times dressing showed the lowest yield of 44.7 tons ha^(-1).
