林業苗圃에 있어서 幼苗의 越冬措置에 關한 硏究 = A Study on How to Winter Seedling in a Tree Nursery

국문 초록 (Abstract)

幼苗의 效果的 越冬措置를 모색코저 樹種別로 몇 가지 材料를 被覆한 結果 그 成績을 要約하면, 다음과 같다.
1. 편백과 화백은 供試樹種中 耐寒性이 强한 樹種임이 밝혀졌으며, 被覆料材로는 材料自體가 氣候가 變動해도 잘 발효되지 않는 落葉이 좋았으며, 더욱이 落葉위에 짚을 덮고 새끼줄로 고정한 것은 바람에 依한 落葉의 분산을 막아 效果的이었다.
2. 樹種과 被覆材料間의 相互關係에 있어서는 耐寒性이 强한 樹種인 편백에다 落葉과 짚을 被覆한 것이 가장 效果的이었다.

To investigate how to winter seedlings effectively, I covered several kinds of testing materials, and the results obtained were summarized as follows:
(1) Hinoki cypress and Sawara cypress were found to be hardly against the cold among the tested seedlings and fallen leaves which do not easily ferment in spite of the changing seasons were found to be the best as materials for covering. It was particulary effective to cover the fallen leaves with rice straws, and to tighten them with straw ropes so that the straws might not be blown away by a wind.
(2) In the mutual relation between species and materials for covering, it was most effective to cover Hinoki cypress which is hardly against the cold with fallen leaves and rice straws.
