Abstract

This study was conducted to get basic information to bio-ethanol production research from sweet sorghum in Korea by grasping research trend in China emphasizing on alternative bioenergy development using sweet sorghum. China is planning to produce bio-ethanol of 510 hundred tons in 2010, 4 million tons in 2020, and 7.95 million tons in 2030. China has a hybrid variety 'Shennong No.2', which has a high bio-mass(stem and grain yield), an excellent photosynthetic capacity, and high alcohol yield, for the bio-ethanol production. In addition, changes of sugar content by varieties and ripening stages were examined, so that could be used indicators of optimal harvesting stage. It is expected that 0.1 MT of un-dried distilled grains and 0.05 MT of distiller's dried grains will be produced in 2010, and the yield of un-dried distilled grains and distiller's dried grains will increase by 1.59 MT and 0.85 MT, respectively, in 2030.

단수수를 이용한 대체 연료 개발에 중점을 두고 있는 중국의 연구동향을 파악하여 우리나라 단수수 연구에 필요한 기초 정보를 제공하고자 본 연구를 수행하였기에 그 결과를 요약하면 다음과 같다. 1. 단수수를 원료로 한 중국의 바이오에탄올 생산 계획은 2010년 51만톤, 2020년 400만톤, 2030년 795만톤이다. 2. 중국은 식량작물과의 경합을 회피하고 새로운 에너지작물을 발굴하기 위해 단수수 품종개발에 역점을 두고 연구를 추진한 결과 줄기, 곡실 모두 다수성이며, 알콜 수량이 많고 광합성 능력이 뛰어난 잡종품 "Shennong 2호"를 개발했다. 또한 단수수 품종별 및 등숙기별 당도 변화를 검토하여 수확 적기 판정과 적기 수확의 지표로 활용하고 있다. 3. 단수수 부산물 활용대책을 수립하여 2010년부터 미 건조증류 곡실 10만톤과 주정박 5만톤을 생산하고 2030년에는 미 건조 증류 곡실과 주정박의 생산량이 각각 159만톤과 85만톤으로 증가될 것으로 전망하고 있다.
