摘要

(一)每年五月中控制林間地樹蔭，保持樹影60%程度，如過蔭之樹枝打下，並將阻害天竺草生育之矮小雜木抽去，此等可供薪木之用。
(二)林間栽培天竺草能防阻豪雨沖刷而有水土保持的功效。
(三)在林間區內毋庸中耕、除雜草、施肥，能達到粗放栽培生產量。（據本分所粗放栽培是每年施用堆肥5,000kg/ha，中耕一次之平均生產量45,000kg/ha）。
(四)林間區生產品質軟嫩可作乾草，牲畜嗜口性頗強。
(五)牧野改良上林間地栽植天竺草，在試驗期間中株高、節數、青草收量等均增加，對照區則反是。

並列摘要

1. The shade of trees did not occupy more than 60% of the space of ground. Branches of trees were to be cut and removed away if the shade was too dark.
2. The plantation of guinea grass in the forest benefited the water and soil conservation.
3. The plantation of grass in the forest saved more labor and compost.
4. The grass harvested in the forest lot was tenderer and had a better palatability.
5. The production of the guinea grass planted in the forest was more than that of the control lot.
