Abstract This paper analyzes two problems existing in the actual teaching of “solubility”: it is difficult for students to really understand the concept directly, and pure knowledge teaching is difficult to reflect the value and significance of subject knowledge. It is proposed that the integration of real industrial production and activity exploration in the “solubility” teaching can help students comprehensively and deeply establish concepts, understand concepts and application concepts, and feel the scientific essence and discipline value. With the theme of “mineral salt”, it presents the teaching record of the integration of real industrial production and activity exploration of salinization, including three links: salt mining in mining area, salt making in plant area and salt cave utilization. Through classroom generation, this paper analyzes the teaching effect, existing problems and the direction of teaching improvement.
