The invention discloses a method for increasing the yield of astaxanthin in haematococcus pluvialis by adding organic acid, and relates to the technical field of microalgae biologication.The method is characterized in that production of astaxanthin in haematococcus pluvialis comprises the two culture stages of a division stage and an induction stage, the organic acid is added in the haematococcus pluvialis culture process, and the haematococcus pluvialis yield is increased. When the haematococcus pluvialis enters the induction period, the illumination culture intensity is improved for culture, and accumulation of astaxanthin is promoted. 本发明公开了一种外加有机酸提高雨生红球藻虾青素产量的方法，涉及微藻生物技术领域，其技术方案要点是，雨生红球藻生产虾青素包括分裂期和诱导期两个培养阶段，在雨生红球藻培养过程中加入有机酸，在雨生红球藻进入诱导期时提高光照培养强度进行培养，促进虾青素的积累。
