Effect of seedling and fertilizering on yield and quality of cultivated Changium smyrnioides / 中国中药杂志

ABSTRACT

<p><b>OBJECTIVE</b>To study the effects of seedling and fertilizer on yield and quality of cultivated Changium smyrnioides and build a basis for its GAP.</p><p><b>METHOD</b>Experiments were conducted to study the effects of seedling quality and different fertilizering measures on yield and quality of cultivated C. smyrnioides.</p><p><b>RESULT</b>The seedling and fertilizering depth affected the yield of roots obviously. Organic fertilizer combined with nitrogen and phosphorus could increase the amylose content obviously.</p><p><b>CONCLUSION</b>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.</p>
