摘要

蒟蒻栽培品種赤城大玉、春奈黑、中國及日本在來之二年生種球，以60×25公分之行株距間作（alley cropping）於平均遮光率62.8%及88.2%之李樹園及檳榔園，種球產量分別為其毗鄰不遮蔭對照區之2.85及1.57倍，差異顯著。各品種平均產量以中國種最高為27,296公斤/公頃，顯著高於春奈黑及日本在來，分別為其263%及533%，並高出赤城大玉46%，而此品種栽培於62.8%遮光率之李樹園下較其他品種之增產潛力大。

Two-year old corms of four A. konjac varieties were intercropped with plum and betel-palm respectively, plots under full light in the vicinity was the CK 62.8% and 88.2% shading under orchards of plum and betel-palm. RCBD at a spacing of 25cm between plants in rows 60cm apart, was adopted to each environment and compaired by combined analysis. As the result, corms grown under plum and betel-palm had higher yield than the CK by 2.85 and 1.57 times respectively. Among all varieties, ”China” which had highest corm yield, gave 27,296 kg/ha, was 2.63 and 5.33 times significantly more than Harunakuro and Nippon-sairai, in the mean time 46% more than Akakioodama. The 62.8% shading under plum trees can induce variety ”China” to justified yield potential.
