收割技術對香茅草油分產量及香茅醛含量之影響

The Effect of Cutting Method on the Oil Yield and Citronellal Content in Citronella Grass

香茅草收割葉片二分之一以上部位每年收五次結果最好，每年四次割取二分之一或三分之二以上部份葉片次之，三分之二部份以上每年收三次者又次之。

The newly designed harvesting method, i. e. cutting a half of leaf blade from the top with 5 times a year, was found much better than the current method in which whole leaf blade was cut 3 times a year.
