台湾龙眼分布全省各地,以中、南部栽培最多,大多分布在海拔400米以下的山坡地带。中、南部夏季高温多雨,冬季温度稍低,干燥,年平均气温22～23℃,年雨量1500～2000毫米,很适合于龙眼栽培,仅台南、嘉义、高雄、南投与彰化等县的龙眼栽培面积即占全省种植面积的85％左右。根据1979年统计,台湾龙眼种植面积73,605亩,总产465,320担。常年产量30～80万担,历史最高产量的1976年达1,038,600担,龙眼生产在全省果品中居第四位。近年来由于农业机构推广高接繁殖,选育当地良种和引种泰国果大、核小、肉脆、味甜等优良品种,使龙眼地位逐渐提高,价值日益增大,大有发展前途。
Taiwan longan throughout the province to the most cultivated in central and southern parts, mostly located in the hillside below 400 meters above sea level.

It is suitable for longan cultivation only in longan cultivation in Tainan, Chiayi, Kaohsiung, Nantou and Changhua counties Area that accounts for about 85% of the province’s planted area. According to statistics in 1979, the planting area of longan in Taiwan is 73,605 mu, with a total output of 465,320 taels. Annual output of 30 to 800,000 Tam, the highest yield in history in 1976 amounted to 1,038,600 Tam, longan production in the province ranked fourth in the fruit. In recent years, due to the promotion of high agricultural reproduction agencies, breeding local varieties and the introduction of Thai fruit big, small nuclear, meat crisp, sweet and other fine varieties, so that the status of longan gradually increased, the value is increasing, promising future.
