In order to explore effect of organic fertilizer on medicinal cultivationof Angelica sinensis, various fertilization regimes including pure organic fertilizer (O,2000 kg·hm-2), pure chemical fertilizer (C, diammonium phosphate, 420 kg·hm-2), and half of organic and chemical fertilizers [1/2(O+C)] were applied under black film mulching in Min County, using no fertilization as the control (CK). During cultivation, early bolting, incidence, yield and root character indicators were measured. The results showed that organic fertilizer could reduce the early bolting rateto 8.0%, which was 19.4%, 15.2% and 7.1% lower, respectively, than in the CK, 1/2(O+C) and C treatments. The angelica yield was increased by fertilizer. The fresh yields in O, C and 1/2(O+C) treatments were increased by 105.9%, 84.6% and 78.2%, respectively, compared with the CK treatment. In the O treatment, the medicinal plant had the longest roots, the most lateral roots, the heaviest single root and the highest yield. Fertilization treatment C resulted in a significant increase in root thickening, but the roots had a high water content, and a higher incidence of root disease. Among the different fertilization treatments the angelica fresh yields ranked: O(9220.6 kg·hm-2)>C(9038.5 kg·hm-2)>1/2(O+C) (8728.4 kg·hm-2)>CK (4897.4 kg·hm-2). Values for a multivariate evaluative index ranked in the same order: O(0.926)>C(0.610)>1/2(O+C)(0.481)>CK(0.190). Ranks for the angelica dry yield (which decided economic profit) were O (3149.2 kg·hm-2)>1/2(O+C) (3098.7 kg·hm-2)>C (2909.2 kg·hm-2)>CK (1707.0 kg·hm-2). In summary, under black film mulching without pollution in Min County, pure organic fertilizer can significantly increase A. sinensis productivity, efficiently reduce early bolting rate, disease incidence and severity and improve medicinal root characters. Its application should be recommended as part of the standard cultivation method for A. sinensis so as to reduce the dependence on chemical fertilizer and promote green organic cultivation.
