천궁은 분류학적으로 어디에 속하는가? | 천궁(川芎, Cnidii Rhizoma)은 산형과(Umbelliferae)에 속하는 여러해살이풀로 원산지는 중국이고, 대한민국, 일본 등지에 분포한다. 기원식물에 따라 중국천궁(Ligusticum chuanxiong Hort), 일천궁(Cnidium officinale), 토천궁(Ligusticum chuanxiong)으로 불린다. | |
천궁의 재배면적과 생산량이 감소한 이유는 무엇인가? | 천궁의 재배면적과 수확량을 살펴보면, 1997년도의 재배면적은 789ha, 생산량은 2,294 M/T (metric ton)이었지만, 2017년도의 재배면적은 185 ha, 생산량은 1,290 M/T으로 현저히 감소하였다(MAFRA, 2017). 이처럼 재배면적과 생산량이 감소한 이유로 첫째, 고온과 가뭄 등의 기후변화에 민감하고 둘째, 연작장해가 심한 작물이기에 지속적으로 재배지를 바꿔줘야 하는 단점이 있기 때문이다[6, 7-8]. 일천궁은 1년 연작만으로도 초작지에 비해 노두수가 60% 가량 감소하며 10a 당 수량은 36% 감소한다[6]. | |
천궁의 원산지는 어디인가? | 천궁(川芎, Cnidii Rhizoma)은 산형과(Umbelliferae)에 속하는 여러해살이풀로 원산지는 중국이고, 대한민국, 일본 등지에 분포한다. 기원식물에 따라 중국천궁(Ligusticum chuanxiong Hort), 일천궁(Cnidium officinale), 토천궁(Ligusticum chuanxiong)으로 불린다. |
