屏東平原蓮霧產業栽培技術，是草根性農業知識，除了園藝試驗所、農 改場等試驗機構彙整與擴散，農業資材行展現另一組推廣體系。本研究以深 度訪談及參與觀察法蒐集資料，得到以下結論：一、因屏東平原各鄉鎮地理 環境的差異，促使蓮霧栽培之各種產期調節管理模式的興起。二、資材行系 統與各地果農的技術交流，形成資材行系統社會網絡，呈現栽培技術的空間 擴散，即：總店－分店－果農的空間結構。此社會網絡的空間互動，再一次 促進栽培技術的創新與擴散。三、當蓮霧產業面臨市場飽和，資材系統以技 術擴散社會網絡的互信基礎，帶領果農轉作他種作物，或轉換為社會資本， 參與蓮霧內外銷集貨作業。以社會網絡聯繫的空間向度，突破在有限短暫時 間內快速集貨的限制，減少交易成本，展現出彈性、即時的特色。

The indigenous agricultural knowledge of wax apple industry in Pingtung Plain was developed and diffused by the agricultural supply shops﹐in addition to the agricultural knowledge and information extension system﹐such as Kaohsiung district agricultural research and extension station. In the fi eld work﹐this research adopted in– depth interviews and participant observation to collect data﹐The followings are what we have found out. First of all﹐the geographical differences of the towns in Pingtung Plain urged several types of wax apple farming techniques. Secondly﹐the development and diffusion of agricultural knowledge among the agricultural supply shops and farmers formed the social networks of the agricultural supply shop groups﹐which led to the emergence of the spatial diffusion of agricultural knowledge in Pingtung Plain. The spatial interaction of these social networks motivated further innovation of farming techniques. Finally﹐the social networks of the agricultural supply shop groups in Pingtung Plain were transformed to the social capital for goods collection of wax apple. This kind of social capital connected the farmers spatially in order to collect the goods fl exibly﹐resisting the time limitation.
