충주 · 중원지역에 있어서 호맥재배(胡麥栽培)에 관한 연구 : I. 전작조건하(田作條件下)에서 번종기와 수확기가 사초용(飼草用) 호맥의 생육특성과 건물생산에(乾物生産) 미치는 영향 I.

국문 초록 (Abstract)

本 試驗은 忠州·中原地域에 있어서 田作이나 畓襄作의 後作으로 飼料作物用 胡麥栽培를 권장하기 위해 品種別 播種刷 및 收穫期가 耐寒性과 生育特性, 그리고 生産性과 消化率 등에 미치는 影響을 규명하고 이 지역에서 靑刈用으로 適合한 胡麥品種을 選拔한 目的으로 遂行하였던 바 그 結果를 要略하면 다음과 같다.
1. 越多前의 生育은 일찍 파종한 것일수록 良好했으며 越冬後 이른봄 生育도 좋았다.
2. 全供試品種중 신기를 제외한 모든 品種이 우수한 越冬性을 나타냈고, 특히 일찍 파종한 것일수록 높은 越冬率을 나타냈다.
3. 播種時期가 이른 것일수록 乾物收量이 많았고, 收穫時期가 늦어짐에 따라 乾物收量도 증가됐다. 品種별로는 Kool-graze, Vita-graze, 팔당 및 재래가 높은 乾物收量을 나타냈다.
4. 葉의 乾物重 比率은 收穫時期가 늦어짐에 따라 低下되었으면 出穗期 이후 그 감소 傾向이 매우 현저했다.
5. 可消化乾物收量은 收穫時期가 늦어짐에 따라 조금씩 증가되거나 거의 비슷하였으나 消化率은 급격히 低下되었다.
6. 이곳 忠州·中原地域에서는 耐寒性이 좋고 早熟하여 이른봄 飼草生産性이 높은 Kool-graze, Vita-graze, 팔당 그리고 재래가 後作物과의 시기관계 등을 고려할 때 적합한 品種이라고 여겨진다.

다국어 초록 (Multilingual Abstract)

This experiment was carried out in order to encouragement of rye cropping under upland or paddy field condition and to select the proper varieties of rye in green cropping system in the Chung-ju, Jung-won areas.
Also this experiment was carried out at different sowing time and harvesting time of rye varieties (Kool-graze, Vita-graze, Pal-dang, Danco, Jae-rae, Kodiak, and Shin-ki). The reasults obtained were summarized as follows:
1. Growth before passing the winter was good in the plots sown early, and it was influenced to growth at following early spring.
2. Most varieties except Shin-ki were good in winter hardiness and high winter hardiness rate was shown in the plots sown early.
3. Dry matter yield increased according as sowing time was early or harvesting time was late and also Kool-graze Vita-graze, Pal-dang, and Jae-rae were higher than other varieties in DM yield.
4. DM weight ratio of leaf decreased according as harvesting time was late and it was that tendency of decrease was apparent after headed.
5. DDM yield increased little by little but IVDM digestibility decreased rapidly according as harvesting time was late.
6. In this Chung-ju, Jung-won areas, varieties of Kool-graze Vita-graze, Pal-dang, and Jae-rae which had good hardiness and high forage production at early spring were thought to be proper varieties.
