岩黄连引种栽培研究

岩黄连 ( Corydalis saxicola Bunting)为石山特有的多年生草本药用植物 ,局限分布裸露石山 ,生于石缝、石穴 ,资源稀少且濒于枯竭。通过近四年的引种栽培研究 ,表明其对丘陵区酸性土壤亦有较强的适应性 ,能正常生长发育 ,种子发芽率可达 4 0 %～ 50 % ,药材产量 (干品 ) 90 0～ 12 0 0 kg/hm2 。报道了其生物学特性和主要的栽培技术。

Study on the introduction and cultivation of Corydalis saxicola Bunting

Corydalis saxicola Bunting is a kind of perennial herb which only grows in limestone hills. To protect this rare and threatened species,its introduction and cultivation have been experimented for nearly 4 years. The result showed it could be planted in acid soil and complete its life cycle. The germination rate in the nursery is 40%～50%. The herb product(dry)is 900～1 200 kg/hm2. This paper reports its biological characteristic and main technique of cultivation.
