為了探索減少白芷早期抽苔與提高產(chǎn)量的施肥方法,應(yīng)用單因素隨機(jī)區(qū)組試驗,研究了不同施肥措施下白芷早期抽苔與產(chǎn)量,結(jié)果表明：磷、鉀肥全作底肥,白芷的早期抽苔率高、產(chǎn)量低;磷、鉀肥一半作底肥,一半作追肥,白芷的早期抽苔率低、產(chǎn)量較高;氮肥平衡施用,白芷的早期抽苔率低、產(chǎn)量較高。

Single factor stochastic experiments were carried out to explore the influence of different methods of fertilizer application on bolting and yield of Anagelica dahurica var. formosasa (Boiss.)Yuan et Shan. Results showed that when the whole amount of phosphate and potassium fertilizer was used as the basal manure,rate of early bolting was high and the yield was lowered. When half phosphate and potassium fertilizer was used as the basal manure and the other half as top dressing. early bolting was retarded with increase of yield. Rational and balanced application of nitrogenous fertilizer also curtailed earlier bolting and resulting in a higher yield.
