無患子耐旱，生長強健，果實富含皂素，具天然清潔及藥用性質，是非常好的造林樹種。本研究以新北市三峽區0.3公頃農田為試驗地，從初始栽種無患子實生苗，並分年度採用添加竹炭及竹醋液、環剝、斷根、截頂、施肥等不同方式處理促進無患子植株生長及提早開花結實。使用6種不同濃度處理，以單獨添加竹炭0.05kg和加入竹醋液稀釋1/500處理對無患子同年度促進高度生長較佳。施肥對無患子生長結實效果影響不大，但對病蟲害具有防治效應。無患子種植後第3 年便開花結果，皂素含量達11.10 mg/g。
Sapindus mukorossii fit drought, strong growth, the fruit is rich in saponin, a natural cleansing and medicinal properties, is very good for planting trees. In this study, the new Taipei City in the Sanxia district area 0.3 hectares of farmland for the test, the plant Sapindus tree from the initial order by year by adding charcoal and different ways of vinegar, girdling, uprooting, truncated, fertilizer and other treatment to promote Sapindus plant early flowering and fruiting. Using six different concentrations of treatment, a separate addition of bamboo charcoal 0.05kg and bamboo vinegar diluted by adding 1/500 of Sapindus in the same year to promote height growth is better. Fertilization had little effect on the growth and fruiting of Sapindus, but it had control effect on pests and diseases. The first three years will have the results of the phenomenon, saponin content of 11.10 mg / g.
