摘要: | 山葵是一種高經濟作物,葵農為了增加山葵產量和品質,在過量施肥的情況下,容易造成土壤和水質受到污染;不但對環境造成衝擊,也亦增加施肥成本。本研究之目的是以阿里山的山葵園為研究對象,考慮到環境成本及經濟效益的因素下,利用GLEAMS (Groundwater Loading Effects of Agricultural Management Systems)模式和CLIGEN(Climate Generator)模式建立一套方法來推估山葵園合理的施肥量。研究結果顯示當施用過量的肥料對於養份吸收並無明顯的增加,反而增加環境負擔,最後所推估的合理施肥量約為1250~1750 kg/ha/yr。本研究可以提供給葵農施肥的參考依據,來改善施肥過量的情形。 As a high economic value crop, Wasabi (Wasabia japonica Matsumura) would be over-fertilized by the farmer to increase the production and improve the quality. When over-fertilizing, not only the fertilizer cost is raised, but also the environment is impacted, i.e. soil and water pollution. This study is to estimate the feasible fertilization of Wasabi on A-Li Mountain by applying GLEAMS (Groundwater Loading Effects of Agricultural Management Systems) model and CLIGEN (Climate Generator) model under environmental cost and economic benefit concern. The result reveals that over-fertilization does not help the absorption of Wasabi, it leads more environmental burden instead. This research shows 1250~1750 kg/ha/yr as the estimated quantifying fertilization which may provide reference to Wasabi cultivation and to avoid the over-fertilization. |
