| Abstract: |
| In order to investigate the effects of Se-neurotrophic agents on yield and main quality ndexes of Angelica sinensis, a field experiment was designed by employing two fertilization levels (low and high fertilizations) and three irrigation methods (AF: all applied as basal fertilizer; HF: half applied as basal fertilizer and half applied as spraying fertilizer; MF: 2/3 applied as basal fertilizer and 1/3 applied as spraying fertilizer). The resulting yield and main quality indexes of Angelica sinensis were measured. The fertilizer application level of Se-neurotrophic agents significantly influenced the yield and main quality indexes of Angelica sinensis, and the effects by high fertilization were more significant than those by low fertilization. Compared to the AF treatment, under low and high fertilizations, MF treatment increased the yield of Angelica sinensis by 9.6% and 20%, respectively. The highest yield by MF treatment was 2 208.33 kg·hm-2 with high fertilization. Under high fertilization, the maximal volatile oil, ferulaic acid and extractives contents by AF treatment was 1.0%, 0.184% and 58.6%, which were 20.5%, 35.3% and 5.6% higher than those by the HF treatment. In conclusion, under high fertilization level (75 kg·hm-2), the MF treatment can help increase the yield of Angelica sinensis, and the AF treatment may help increase the quality of Angelica sinensis. |
