백출(Atractylodes macrocephala Koidz)의 파종방법과 종근중에 따른 생육과 수량

Abstract

This study was conducted to investigate the effects on the growth and yield by the differentseeding methods and cultivating root weight in Atractylodes macrocephalaKoidz. Seedingdistances were different such as 5× 5 cm, 5× 10 cm, 10× 10 cm, 10× 15 cm by the handseeder and 15 cm seeding in drill. Emergence date, plant height were not significantlychanged with seeding space, but the number of leaf, fresh weight of above-ground part andfresh weight of root were increased in the sparse seeding compared with the dense seeding.The highest fresh root yield was 1,012 kg/10 a at the 5× 5 cm. Roots yield was increased inthe sparse seeding compared with the dense seeding, but the highest number of roots above16 g yield was observed at the 10× 10 cm seeding distance. Emergence date was faster 1~3day root weight above 6 g than that root weight 5 g. The plant height, number of stem andfresh weight of above-ground part were more increased as the root weight was heavier. Thegrowth of underground part were more increased as the root weight was heavier, yield wasincreased about 27% to 112% compared with root weight above 6 g than that of 134.6 kg/10a with root 5 g.
