不同覆蓋物對香茅油分含量及香茅醛含量之影響

Abstract

本試驗為探討不同覆蓋物對香茅草油產量及香茅醛含量之影響，計分4種處理，4重複。試驗結果顯示不同覆蓋物對產草影響不大，而對油分中香茅醛含量有顯著效果，尤以D處理覆蓋黑已不透明塑膠布老含量為最高。 Three kinds of mulching materials were tested on the citronella field for the of obtaining better grass growth and increasing the yield and citronellal content of oil. Though significant differences in grass growth and oil yield were not found among all treatments tested, however, the citronellal content of oil was much increased by the mulching with black opaque plastic film.
