[Effect of seedling and fertilizering on yield and quality of cultivated Changium smyrnioides].

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.
