Abstract
龍眼（Dimocarpus longan Lour.）為臺灣重要果樹與蜜源作物，近年產業同時面臨產期集中、鮮果不耐貯藏、颱風豪雨風險、隔年結果，以及暖冬造成花芽分化不足與開花不穩等挑戰。臺灣龍眼栽培由早期粗放管理逐步轉型，1960年代以地方品種調查與高接更新奠定產業基礎，並以'粉殼'等品系成為主流；近代則推動矮化栽培、果品評鑑與加工品牌化，龍眼乾兼具內需與外銷市場。然而，加入WTO後進口龍眼乾增加，亦加深國內加工端之競爭壓力。本文彙整世界龍眼產業現況，指出中國為最大生產與進口國，泰國與越南為主要出口國；越南及泰國已廣泛運用氯酸鉀等催花技術以進行產期調節與周年生產。綜合國內外經驗，未來臺灣可評估在南部較溫暖產區導入產期調節之配套管理，並強化病蟲害（如荔枝椿象）之區域防治、加工差異化與品牌策略，以提升產業韌性與競爭力。
Longan (Dimocarpus longan Lour.) is an important fruit tree and nectar crop in Taiwan. In recent years, the industry has faced challenges such as concentrated harvest periods, poor storability of fresh fruit, typhoon risks, alternate bearing, and unstable flowering caused by warm winters and inadequate bud differentiation. Longan cultivation in Taiwan has gradually shifted from extensive management to more refined practices. Since the 1960s, surveys of local varieties and grafting renewal established the foundation of the industry, with cultivars such as ‘Fenke’becoming mainstream. More recently, dwarf cultivation, fruit quality evaluation, and branded processing have been promoted, with dried longan serving both domestic and export markets. However, after Taiwan’s accession to the WTO, imports of dried longan increased, intensifying competition in domestic processing. This paper also reviews the global longan industry, noting that China is the largest producer and exporter, while Thailand and Vietnam are major exporters. Both countries have widely adopted aluminum foil flower induction techniques to regulate production periods and achieve year-round supply. Drawing on domestic and international experiences, Taiwan may consider introducing production period regulation in warmer southern regions, strengthening regional pest control, and enhancing product differentiation and branding strategies to improve industry resilience and competitiveness.
