摘要

本試驗旨在探討綠竹地下莖清理時期對竹筍生產之效應，試驗自2010 年至2012年於臺北市士林區連續進行3 年，地下莖清理時期分別為11 月、12 月、翌年1 月、翌年2 月及翌年3 月。2010 年以11 月及12 月處理之竹筍產量最高，以3 月處理者最低，其間具顯著差異。2011 年以11 月處理最高，次為2 月處理，仍以3 月處理最低，亦具顯著差異。2012 年各處理產量間均未達顯著差異。綜合3 年試驗結果，11-12 月進行綠竹地下莖清理具產量高的趨勢，且3 年平均產值也最高，故建議綠竹地下莖清理應於11-12 月間進行為佳。

The aim of this research was to study the influence of periods of clean-up rhizome on green bamboo shoot production. The experiment was carried out from 2010 to 2012 in Shihlin, Taipei city. The clean up, fertilization and hilling treatments were done in November, December, January, February and March, respectively. The results showed that the yields of bamboo shoots in November and December treatments were significantly higher than those in February and March in 2010. In 2011, the yield of bamboo shoots in November was significantly higher than those in December, February and March treatments. The yields among all treatments were not significantly different in 2012. According to the results, the yields of bamboo shoots and output values in November and December treatment were the highest in 3 years. Therefore, rhizome clean-up for green bamboo should be done from November to December.
