Abstract：In order to study the effects of the effects of fertilizer types and topdressing on production of Angelica sinensis of the Mingui 6， the two-factor randomized block design were carried out in the field. The results showed that the main agronomic characters of Angelica sinensis are better， the yield increase is significant， and the economic net income is larger when it comes to the technical scheme of topdressing urea 150 kg/hm2 in early July.
