摘要

為配合政府推行綠能發電結合農業生產的政策，本試驗目的為探討在營農型光電溫室的遮光環境中，適合秋冬季栽培的蔬菜種類與品種。本試驗於遮蔽率40%之屋頂式營農型光電溫室下進行有機葉菜類栽培評估，評估結果以青梗白菜「綠光一號」與「綠愛」之產量較佳；小白菜篩選出「泉州白菜」、「蜜雪兒」、「翠鳳」與「503號蚵仔白菜」；油菜為「青龍」、「阿茵」與油菜（未有商品名；鄭奇種苗）；芥藍則以F1品種「一嘉」與「藍星」產量顯著較高；芥菜以「台農3號」與「青和」之單株重與小區產量較佳。目前葉菜類品項評估結果中，小白菜可達農業統計年報不結球白菜平均3年單位面積產量70%，其採收期為定植後16 d，相對較其他蔬菜短、且複作指數高，為目前評估結果中最適合在營農型光電溫室下栽培的葉菜品項。由本試驗環境條件推論，其他葉菜類如透過栽培技術改進與品種選擇，投入適當資源、資材，可能也有機會達到常態環境下70%產量。

Due to the government paying much attention to the solar energy issue and eager to combine with agricultural production, agrivoltaic systems gain much attention recently. The objective of this study was to evaluate growth of different vegetable species and cultivars that suitable for winter cultivation in a photovoltaic greenhouse with 40% coverage of solar panel on the roof. Results showed that cultivars of Pak-Choi (Brassica rapa ssp. chinensis var. communis) 'Lü Guang No.1' and 'Oprah' had the best yield and flavor among others. For non-heading Chinese cabbage (Brassica campestris L. spp), cultivars 'Quan Zhou Bai Cai', 'Mi Xue Er', 'Cui Feng', and 'E Zi Bai Cai No.503' performed the best. 'Qing Long', 'All In', and rape bred by Cheng Chi Seed Grower Company grew better within the tested cultivars of rape (Brassica rapa ssp. chinensis var. utilis). The yield of F1 cultivars of Chinese kale (Brassica oleracea L. Alboglabra Group) 'Yi Jia' and 'Lan Xing' were significantly higher than others. Mustard (Brassica juncea Coss.) 'Tainung No.3' and 'Qing He' had the highest average weight and yield. Comparing vegetable species for the experiment, non-heading Chinese cabbage (Brassica campestris L. spp) obtained 70% of the 3-year average yield of that grown in normal condition and can be harvested in about 16 d after transplanting, shorter than other vegetable species with high multi-cropping index. As a result, it is the most adaptable vegetable of this study. The vegetable species without acceptable yield production could be further enhanced by improved cultural practices.
