陈化兰主持国家禽流感参考实验室，系统开展了中国禽流感流行病学监测和研究工作，取得了一系列重大进展和创造性研究成果，初步阐明有关禽流感病毒的分子遗传、抗原变异及致病性演化规律，为疫情的预警预报、防制策略、诊断试剂及疫苗研制与使用提供了全面的科学依据。在防制禽流感期间，迅速准确确诊来自全国各地的大量样品，对疫情的及时有效控制起到了关键作用，她主持研制的有关禽流感灭活疫苗已累计推广应用60亿羽份以上，为防控禽流感疫情作出了重大贡献。

主持国家禽流感参考实验室在动物流感尤其是禽流感的流行病学、诊断技术、新型疫苗研制、分子演变及分子致病机制等方面取得了一系列重大进展和创造性研究成果，研制成功了H5 亚型禽流感灭活疫苗和新型“禽流感、新城疫重组二联活疫苗”，代表了禽流感疫苗研制的国际先进水平和发展趋势，推广应用后，极大地提高了中国乃至世界防控禽流感的能力，具有十分重要的社会经济及公共卫生意义。

2013年4月，陈化兰和她的科研团队发现，在中国导致人感染的新型H7N9流感病毒，与同一时期存在于活禽市场上的H7N9禽流感病毒高度同源，在国际上首次从病原学角度揭示了新型H7N9流感病毒的来源，为中国科学防控H7N9禽流感提供了重要依据。5月，她们又发现H5N1病毒确有可能通过与人流感病毒的基因重配，获得在哺乳动物之间高效空气传播的能力，从而具备引起人间大流行的潜力，从全新的角度揭示了H5N1病毒对全球公共卫生构成的现实威胁。7月，她和科研人员研究发现，H7N9病毒对禽类无致病力，但该病毒侵入人体发生突变后，对哺乳动物的致病力与水平传播能力得到明显增强，从而揭示了H7N9病毒存在较大人间大流行的风险。这些成果先后发表在《科学通报》英文版及《科学（SCIENCE）》杂志上。

2019年11月20日，中国农业科学院发布了10项能够充分代表2018年我国农业科技前沿研究水平、取得重大突破性进展的基础科学研究成果，其中包括：H7N9高致病性禽流感病毒的快速进化及其成功防控。该研究由中国农科院哈尔滨兽医研究所陈化兰院士团队主导，通过对家禽禽流感病毒进行大规模监测，对分离的H7N9高致病性禽流感病毒进行系统研究，成功研发了H5、H7二价禽流感灭活疫苗，监测结果显示疫苗免疫后有效阻断了H7N9病毒在家禽中的流行，在阻断人感染H7N9病毒方面也取得了“立竿见影”的效果。

1994年以来，陈化兰一直从事禽流感及猪流感相关基础研究和应用研究，先后主持国家“攻关”、“863”、“973”、国家自然科学基金等科研项目20多项。

截止到2014年，陈化兰在国际重要学术杂志发表禽流感研究相关SCI论文50多篇；已获得6个禽流感疫苗新兽药证书，其中3个为基因工程疫苗；获得7项国家发明专利。
