摘  要:
研究表明,祁白芷积累的大量矿质元素中氮、钾最多,磷最少。祁白芷对氮素的主要积累期是在生长140d以后,吸收的氮素主要积累在地上部;磷素含量在生长90d时最高,此时磷素分配以地上部为主,在生长140~190d时磷素积累量最大,主要积累在地下部;钾素含量在生长165d时最高,在生长140~190d时积累量最大。因此,在祁白芷生产上,前期宜少施氮肥、多施磷肥,在生长140d以后追施氮、磷、钾肥。

摘  要:
Among the nutrients Angelica dahurica accumulated, the amount of N and K is more than P. After grown for 140 days, the plant had the largest accumulation amount of N, which mainly distributed in the aboveground part. Plant's content of P was higher when grown for 90 days, which distributed more in the aboveground part. The accumulation of P reached the highest when grown for 140~190d, distributed more in the underground part. The content of K reached the highest amount when grown for 165 days. The plant accumulated K rapidly when grown for 140~190d. Therefore, lower amount of N with higher amount of P should be applied in early period. And after grown for 140 days, N, P, K fertilizers should be used in practice.
