Abstract: In this paper,the experimental content of plant physiology is innovated.The marine characteristics were introducted.The marine algae-based experimental materials were selected to study the physiological properties of algae.At the same time,increase the opening of the report content in the research experiment.Reform the assessment system.Increase the proportion of research experiments.With a view to changing the existing research experiments outdated,curing methods,lack of innovation capacity situation.Practice shows that the reform of the experimental study of distinctive marine features can effectively develop students' comprehensive experimental skills and innovative ability.
