4月份見識之旅活動，於2023年4月22日由呂明澐小姐帶領12位祐生見習生及其家長們，至雲林進行麥寮綠能發展暨黑豆蔭油文化之旅。
　　For the study tour of April 22, 2023, Ms. Lu Ming-yun led 12 ARF interns and their parents on a trip to learn about green energy development and black bean soy sauce in Mailiao Township, Yunlin County.
　　
　　上午行程造訪位於西螺延平老街上的丸莊醬油博物館，首先透過影片介紹丸莊醬油悠久的品牌歷史，接著引導見習生進行壺底蔭鼓DIY體驗，在導覽人員解說下，眾人一步步將初次培麴發酵後的黑豆以清水洗麴、浸泡、瀝乾並裝進甕裡，在等待菌種發酵機制啟動以進行拌鹽封甕的期間，導覽人員向眾人展示完整丸莊醬油製程中的曬缸場，為了對比先前具體而微的DIY流程，特別打開其中一座展示缸，讓眾人看缸裡發酵狀態，淺嚐一小口缸中尚未調味過的醬油，讓見習生感受到發酵的奧妙和變化，更讓眾人期待六個月後親手釀製的醬油是否也如今日品嘗到的一樣鹹香甘甜。話別丸莊後接著造訪西螺大橋，這座橫跨濁水溪兩側大橋，除了建設工程本身是美援時代的產物，其於1953年通車後進一步強化南北運輸，繁榮了地方經濟，但隨著糖廠停辦及公路交通持續拓展，西螺大橋的運輸功能逐漸被取代，最後改換紅色新妝轉型為觀光大橋。隨後導覽人員沿途講解西螺老街的現代主義建築特色，大部分建築自1935年中部大地震後改建遺留至今，除了應用開模印花、洗石子、貼面磚的裝飾藝術手法，也不忘融入鄉土質樸的風格。
　　The morning's itinerary brought everyone to Wuan Chuang Soy Sauce Museum located on Yanping Old Street in Xiluo. After learning about the history of the brand through a video, the interns tried their hands at DIY fermented black bean. Instructed by the tour guide, everyone started by washing off the mold culture from the fermented black beans, and then soaking, draining and storing the fermented black beans in an urn. While waiting for the fermentation process to start before mixing in the salt and sealing the urn, the tour guide showed everyone where all the urns are being placed for the soy sauce making process. To allow everyone to make comparison, one of the urns was opened so the fermentation condition could be seen and everyone could taste a little of the unflavored soy sauce. Having experienced the wonder and transformation of the fermentation, everyone looked forward to tasting the same salty soy sauce with its sweet undertones when their DIY soy sauce is ready in six months. After leaving the Museum, everyone visited Xiluo Bridge that spans both sides of Zhuoshui River. The tour guide said the bridge was a new-age construction in the period of the U.S. aid. Since its use in 1953, it has further improved transportation between southern and northern Taiwan, prospering local economy. The transportation function of Xiluo Bridge was gradually replaced after Taisugar factory closed and road transportation network continued to expand. Today, it is painted a vibrant red color and functions as a tourist attraction. Along the way, the tour guide introduced the modernist style of architecture on Xiluo Old Street. Most buildings were rebuilt after the massive earthquake in central Taiwan in 1935, and featured art deco design such as open-mold printing, sand-washed pebbles and wall tiles, with a touch of rustic village style.

　　下午前往位於雲林麥寮的晁陽綠能休閒農場，這是全台首座結合太陽能發電的有機農業園區。導覽老師向眾人展示太陽能發電機，說明發電機之構造，因雲林位於北迴歸線以北，接收到最多的日照太陽能板傾斜角度為23.5度，形成具有特色的斜屋頂。太陽能發電需要廣闊的空間，為有效運用空間，下方發展綠色農業，遵循此模式的綠能溫室農場內共有22座，所產生的電力足以供應1400個一般家庭使用。農場內的綠色農業有禽類養殖、復育黃斑蟋蟀、種植蔬果，導覽老師帶領眾人參觀其中一項─全罩式太陽能溫室菇舍，透過採摘珊瑚菇，了解生長多次的菇菇太空包雖已缺乏養份，無法再次長出珊瑚菇，卻可用來製作成天然肥料，成為對農業有益的培養土和蚯蚓糞土以達到永續利用。實地參訪讓見習生們對於農電共生的永續模式有了深刻的認識。至此，本日活動已近尾聲，大家一起合照留念後搭車返程，並期待於下次見識之旅再相見。
　　In the afternoon, the tour took everyone to Chao Yang Solar Farm in Mailiao, Yunlin. This is Taiwan's first organic farm that has its own solar power plant. The tour guide showed everyone the solar power generator and explained its construction. As Yunlin lies north of the Tropics of Cancer, the solar panels are placed at 23.5-degree angle to receive the most sunlight, forming a unique sloping roof. As solar energy infrastructure requires extensive land use, green farming is developed below to utilize space more effectively. There are a total of 22 solar-powered greenhouses in the farm that utilize this model, generating enough to supply electricity to 1400 normal households. Green agriculture in the farm consists of avian husbandry, restoration of field crickets, and fruits and vegetables planting. While picking golden oyster mushrooms in a fully covered solar-powered mushroom greenhouse, everyone learned that a mushroom substrate bag that has been depleted of nutrients after multiple reuses can be used to make natural fertilizer, becoming beneficial cultivation soil and vermicompost. The on-site visit gave interns a deep understanding of the sustainability model of agro-photovoltaics. As the day's tour came to an end, everyone took a group photo before heading back home and looked forward to the next study tour.
