本研究旨在探討五溝村陸域植栽、水域植栽、產業植栽種類及其應用。研究結果發現,就陸域植栽而言,桂竹、刺竹可作為客家夥房之建材,玉蘭花、桂花、馬茶花等香花植物,可作為裝飾、民俗節慶活動、庭園景觀、環境綠美化之應用。民國70至80年代白頭天胡荽、粉綠狐尾藻、光冠水菊、異葉水蓑衣、巴拉草等外來種水生植物,適合當地環境,生長快速,導致探芹草、屏東石龍尾、長柄石龍尾、白花水龍等當地水生植物棲地受到影響,需要進行復育及保育。產業植栽方面,民國40至60年代地方產業多以種植水稻為主,且農業生產技術進步,水稻產量增加、成為當地居民收入來源,民國70年代以後,農地種植檳榔、香蕉等農作物的收入比水稻高,逐漸取代了水稻。
The objective of this research is aimed to investigate plants of land (terrestrial plants), water (Aquatic plants), and industrial plants and its application at Wugo Village. Results of investigation showed that among land plants, the Makino bamboo and Bambusa can be used as the building material for Hakka housing construction; aromatic plants such as Magnolia (Michelia alba DC.), Osmanthus (Osmanthus fragrans Lour.), and horse Camellia (Tabernaemontana divaricata (L.) R. Br. ex Roem.) can be used for decoration, folk festival activity, landscape, and environmental greening. For aquatic plants, the native plants of celery grass (Hydrolea zeylanica (L.) Vahl), the Pingtung limnophila (Limnophila sp.), skillet limnophila (Limnophila trichophylla Komarov,), and white flower ludwigia (Ludwigia adscendens (L.) Hara) needed to be preserved and conserved when territory was invaded by the vigor alien aquatic plants such as coriander (Hydrocotyle leucocephala Cham. & Schltdl.), light green Myriophyllum (Myriophyllum aquaticum the (Vell.) Verdc.), light crown water daisy (Gymnocoronis spilanthoides (D. Don ex Hook & Arn.) DC.) alternate-leaf hygrophila (hygrophila difformis (L. f.) Blume (L. f.) Blume), and Bala grass (Brachiaria mutica (Forssk.) Stapf) occurred during 1980-1990. For industrial plants, rice was the major crop during the period of 1950-1970. With the advance in production technology, the yield of rice was increased and became the major income for local inhabitants. After 1980, rice was replaced by higher income crops such as betel nuts (Areca catechu L.) and banana (Musa sapientum L.).
