Abstract
為了探討山葵之適應性與新地區栽培對墨入病（Phoma wasabia YOKOGI ）蔓延之遏阻程度，乃選定本省中部海拔1200M 高冷地信義與溪頭兩地方，分別採用人工架設黑色塑膠網與不同自然環境試作發現：1.信義試區：所種植山葵之生育，以架設75~80%遮蔭網較佳，種植後90 天之平均株高為16.9cm，平均葉數為17.8 葉。經測定其實際遮蔭率恰為70%，適合山葵之生長，惟其後因栽培環境溫度偏高、濕度偏低，並發生白誘病，而於成熟前乾枯死亡，因之信義地區可能較不適合種植山葵。2. 溪頭試區：發現種植於空曠地山葵之生育較衫樹下良好，平均公頃根莖量為17,125kg，葉柄量為26,75Dkg ，鬚根量為5,625kg。平均公頃估計收入可達3,596,250 元，比杉樹下種植區多收1,396,250 元。於溪頭試區就氣溫因子加以調查，發現溪頭試作區栽培環境可媲美阿里山產區，也比日本伊豆產區優異，且產量高於日本伊豆地區。墨入病罹病率調查結果，空曠地區者達100%，根莖平均罹病長度為5.2cm，杉樹下試區罹病率為80%，根莖平均罹病長度4.2cm，經研判其因可能為種苗帶菌所引起。In order to find out some new places suitable for the growth of wasabia and to minimize the severe damage caused by phoma blight disease, experiments were conducted at Hsinyi and Hsitou areas, both are 1200m above sea level and in Nantou county.
For lack of natural shading, the Hsinyi plots were shaded with black polyethylene nets which can reduce different amount of light intensity. The results in Hsinyi area indicated that the light intensity of the treatment with 75-80% shading net, which reduced 70% of the light, was favorable to the growth of wasabia. The mean number of leaves per plant and plant height were 17.8 leaves and 16.9cm at the 90th day after planting, However, the plants were possibly killed by high temperature, low humidity, and the infection of white rust disease during the maturity time. Therefore, Hsinyi area was not suitable for the growth of wasabia.
