OBJECTIVE: To study the effects of seedling and fertilizer on yield and quality of cultivated Changium smyrnioides and build a basis for its GAP. METHOD: Experiments were conducted to study the effects of seedling quality and different fertilizering measures on yield and quality of cultivated C. smyrnioides. RESULT: The seedling and fertilizering depth affected the yield of roots obviously. Organic fertilizer combined with nitrogen and phosphorus could increase the amylose content obviously. CONCLUSION: In cultivation, the seedling (root length > 5.0 cm, root diameter > 0.3 cm, fresh root weight > 0.3 g) is optimal. The ideal combination is nitrogen, phosphorus and organic fertilizer. The suggested fertilizering depth ranged from 10 to 15 cm.
