Abstract

Angelica sinensis (Oliv.) Diels, called DangGui in Chinese of the family Umbelliferae is a well-known perennial medicinal plant with versatile medicinal properties in the Chinese traditional medicine. In this research, a field experiment was carried on to understand the effect of organic and chemical fertilizers on biomass, ferulic acid content, essential oil yield, essential oil content and compositions of A. sinensis in Minhe county of Qinghai province of China. The treatments were: control (without fertilizer), pig manure (PM, 13.5 t ha−1), sheep manure (SM, 9.8 t ha−1 ), chemical fertilizers (CF, 60, 45 and 30 kg–ha−1, nitrogen (N), phosphorus (P), kalium (K), respectively), organic fertilizer (OF, 600kg ha−1), pig manure + chemical fertilizers (PM+CF, 6.75 t ha−1 + 30-27.5-15 kg ha−1 N, P, K) and sheep manure + chemical fertilizers (SM+CF, 4.9 t ha−1 + 30-27.5-15 kg ha−1 N, P, K ). PM+CF treatment produced 31.4% higher crop yields and 49.4% higher essential oil yield over the control, respectively. The highest mean values of chlorophyll-a (2.07mg·g−1), chlorophyll-b (0.61mg·g−1) and total chlorophyll (2.68 mg·g−1) were acquired under the treatment of PM+CF. The major component of essential oil of A. sinensis is ligustilide. The highest amount of ligustilide was acquired under the treatment of PM+CF. The ferulic acid was increased (48.85% compared with control) under the treatment of PM+CF. The P and K contents of the soil were increased under the treatment of PM+CF (around 30.13% and 25.53% higher over the control, respectively). Our studies indicated that the combined application of fertilizers improved soil nutirent, leading to increase in biomass yield and improved the quality of A. sinensis.
