Abstract

To investigate the suitable growing area for Italian ryegrass (cv. Kowinearly and cv. Green-Call), we survey the different effects of climatic conditions on plant growth in the east (hereafter termed Yeongdong) and west (hereafter termed Yeongseo) of the passes in Gangwon Province. The Italian ryegrass was grown in Gangneung of Yeongdong and Wonju and Chuncheon of Yeongseo. The plants showed growth differences depending on the cultivated regions between before and after wintering. The Italian ryegrass for pre-wintering showed the relatively long length of plant height in Wonju. While, we observed the relatively tall plants for growing- and harvesting-period after wintering in Gangneung. The increased plant height in Gangneung was closely related to all climatic conditions for the growing period and mean- and lowest-temperature for the harvesting period, respectively. The amount of dry matter was 7,490 kg/ha for Kowinearly and 6,490 kg/ha for Green-Call in Gangneung, which has a higher yield than Chuncheon and Wonju. The relative yield index of dry matter was 77% (Kowinearly) and 78% (Green-Call) in Chuncheon and 84% (Kowinearly) and 71% (Green-Call) in Wonju compared to Gangneung as the standard region. Thus, we suggest that Chuncheon and Wonju are the possible areas for cultivation of Italian ryegrass, considering that Gangneung was the optimum growing area in Gangwon Province.

본 연구에서는 농촌진흥청 국립축산과학원에서 개발된 품종 중 추위에 강한 내한성을 가진 품종 중 조생종으로는 '코윈어리', 극조생종은 '그린콜' 을 공시 시료로 하여 강원지역의 기상과 이탈리안 라이그라스의 두 품종(코윈어리, 그린콜)의 생육 간 상관관계를 보고, 지역별로 이탈리안 라이그라스 두 품종의 재배 가능성을 보고자 하였다. 지역별 월동 전 이탈리안 라이그라스의 생육에서는 춘천지역이 출현율과 분얼경, 지하부의 생육이 가장 좋고, 초장의 경우 다른 지역의 중간 정도이며, 원주 지역은 출현율이 춘천보다 낮았으나, 초장의 생육이 춘천, 강릉지역보다 좋았다. 강릉지역은 태풍으로 원주와 춘천지역보다 월동전 생육과 출현율이 많이 저조하였다. 하지만 수확기인 5월에는 초장의 길이가 강릉, 춘천, 원주 순으로 강릉이 특히 매우 높게 나타났고, 수확기의 초장은 최저기온 및 평균 기온과 밀접한 상관관계를 보였다. 이러한 결과는 월동 중 및 월동 후 이후 생육기에 변화하는 기상 조건 중 최저기온과 적산온도가 이탈리안 라이그라스의 생육에 영향을 주고 있음을 제시한다. 지역별 코윈어리의 건물수량은 강릉이 7,490 kg/ha로 춘천, 원주보다 많았다. 그린콜의 경우에도 강릉의 건물수량이 6,490 kg/ha로 춘천, 원주보다 많았다. 재배 적지인 강릉을 기준으로 이탈리안 라이그라스 상대 건물수량 지수는 춘천이 77~78%, 원주가 71~84%을 보여 춘천 지역에서 IRG 재배가 가능지역으로 평가되지만, 최적 재배 지역은 아니고 재배 불안전 지대로 판단된다. 따라서 중북부 지역인 강원도 경우 IRG 재배에 미치는 환경 요인이 이탈리안 라이그라스 생육과 수량에 주요한 영향을 주고 있음을 제시한다.
