Abstract

On April 4 to 6, 2005, there was a huge fire in Yangyang-gun, Kangwon-do, Korea, which burned over 250ha of forests and 246 buildings including 160 houses. The effects of reseeding rate and timing on productivity and nutritive value of forages in the forest fire burnt pasture in this study were investigated. The effect of reseeding could not be seen in the burnt pastures in terms of forage productivity and quality in short term but there was a long-term effect particularly with higher reseeding rates at later days after the fire on forage botanical composition. We concluded that forest fire brought reduction in pasture forage yield for a short period but it did not make a significant effect for a long term.

2005년 4월 4일부터 6일까지 강원도 양양군에 대형산불이 발생하여 산림 250 ha를 포함하여 인근 농가의 목초지가 피해를 입었다. 따라서 본 연구는 산불 피해 초지에서 보파시기와 보파량이 초지의 생산성과 사료가치에 미치는 영향을 구명하기 위하여 수행되었다. 처리는 대조구, 산불발생 10일후에 추천 파종량의 30%와 50%, 20일후에 30%와 50% 보파를 포함하여 6처리를 공시하였다. 그러나 본 연구에서 산불 피해 목초지에서 생산성과 사료가치에 미치는 보파의 효과는 뚜렷하게 나타나지 않았다.
