Abstract

In order to identify the causes of various problems related to forage crop growth, such as winter survival, coldness, rainfall, drought etc., and to provide basic data for the stable production and supply of forage year round, we performed a growth survey after the wintering of winter forage crops grown from mid-Sep. 2014 to late-Feb. 2015. The growth of winter forage crops after wintering in the country was generally bad. As shown in the regional distribution in the country, regions with 80% or higher winter survival rates comprised 66%, regions with 79 to 50% winter survival comprised 24.9% and regions with less than 50% winter survival comprised 9.1%. In conclusion, the average winter survival rate was 79% in the country. Winter survival rate and coverage rate after the wintering of winter forage crops under installed drain channels in paddy fields were good at 83% and 80%, respectively. However, the rates without installed drain channels were bad at 67% and 66%, respectively. It was predicted that the crop production of winter forage crops was reduced by 10-15% in Gangwon, Chungbuk, Chungnam, Gyeongnam and Jeonnam regions, reduced by 30% in Gyeonggi, Gyeongbuk and Jeonbuk regions and reduced overall by approximately 19% nationwide.

본 연구는 2014 / 2015년 동계 사료작물의 월동 후 생육조사를 통하여 전국적인 작황을 파악함으로서 사료작물 생육에 문제점이 있을시 근본 원인을 구명할 수 있는 기초자료로 이용하거나 조사료의 연중 안정 생산, 공급에 도움을 주고자 수행하였다. 2015년도 전국 동계 사료작물의 월동 후 생육 상황은 전반적으로 저조하였는데, 월동률 분포에 따른 지역별 분포 상황을 살펴보면 월동률 80% 이상인 지역이 66%, 월동률 79~50% 분포지역이 24.9%, 50%미만 지역이 9.1%의 지역별 분포를 나타내어 전체적으로는 79%의 월동률을 나타냈다. 월동 후 월동률 및 피복률은 배수로가 설치된 논에서는 각각 83%와 80%로서 양호했으나 배수로가 설치 안 된 습한 논에서는 각각 67%와 66%로 낮은 경향을 나타냈다. 전국 동계작물 조사료 생산량은 강원, 충북, 충남, 경남, 전남지역은 10~15%, 경기, 경북, 전북지역은 약 30%의 수량감소가 예상되어 전국적으로 약 19%의 수량 감소가 예상되었다.
