초록

공시품종인 Burley 21을 수확한 후 건조하고 무더운 시기에 처리하여 건조하우스의 환기시기, 환기량 및 달줄간격 등의 건조실관리에 따른 급건조방지 방법을 밝히고자 시험한 결과 요약하면 다음과 같다. 1. 건기에는 건조시 시종환기구에서 온도가 낮았고 급건엽발생도 제일 적었다. 2. 급건엽발생시기는 황변말부터 갈변말까지로 이 시기에 탈수를 지연시키는 것이 가장 중요하다. 3. 급건엽발생이 적을수록 품질 및 물리성이 양호하였다. 4. 측면을 1.5m로 충분히 환기시킨 구에서 급건엽발생이 가장 적었다. 5. 달줄간격을 좁힐수록 온도에는 크게 영향을 미치지 않았으나 온도는 높게 유지하여 급건엽발생을 크게 감소시켰다. 6. 급건엽의 내용성분은 충분히 분해가 일어나지 않았다.

The studies were carried out to investigate the occurrence of excessive dried leaves during burley tobacco curing. Six different periods of ventilation during the entire stage of curing were applied. And also 3 different heights of rolling up polyethlene film for side ventilation of the curing house combined with 4 different spaces between garlands were applied from after yellowing. The high air temperature and low relative humidity from end of yellowing to end of browning stage were the most critical to occur excessive dried \eaves. As side ventilation was continued for the entire stage of curing, air temperature in curing house was lower and occurrence of excessive dried leaves were remarkably decreased. The air temperature was not affected on hanging spaces, but relative humidity that resulted significantly in decreasing of the excessive dried leaves was increased by narrowing of hanging spaces. As excessive dried leaves were increased, its price per kg was lower, its physical properties was worse and its total nitrogen and total suger were higher than those of normal cured leaves.
