As an effective carrier to cultivate students' practical skills and innovative ability, extracurricular scientific and technological activities of college students provide a brand-new platform for innovative education. The author summarizes, thinks and explores the extracurricular academic and scientific activities of students in our school in recent years, in order to better grasp the development trend of this activity and advance the vigorous development of students' extracurricular scientific and technological activities with the times. Keywords extracurricular activities; Scientific and technological activities; Innovative talents are the foundation of innovation, and the goal of building an innovative country needs innovative talents to achieve. Therefore, cultivating students' innovative ability is an important task of higher education, and extracurricular scientific and technological activities of college students are an important carrier and effective way to cultivate students' innovative ability. 1 the importance of extracurricular scientific and technological activities to cultivate college students' innovative ability 1 an effective carrier to cultivate college students' innovative consciousness. Students not only strengthen the scientific awareness of "loving, learning and using science" in exploratory extracurricular scientific and technological activities, but also exercise their practical skills, realizing the transformation from scientific knowledge to practical skills. In addition, the development of mass students' scientific and technological activities will drive and create a rich atmosphere, and then drive and guide a large number of students around to invest in scientific research practice. 1.2 the main position of college students' innovative practice: scientific and technological activities are scientific, practical and exploratory, highlighting the main characteristics of "innovation", making extracurricular scientific and technological activities one of the main channels for college students to participate in innovative activities. At the same time, it has the characteristics of popularization and popularization, and has a broad mass base, which provides a stage for every student to participate in innovative activities. 1.3 An important way to improve the scientific research ability of college students. Carrying out extracurricular scientific and technological activities can not only enhance college students' awareness of advocating science and pursuing true knowledge, but also play an important role in improving their scientific research ability, especially in cultivating their innovative spirit and practical ability. Through hands-on and practice in various scientific and technological activities, students' ability to discover, analyze and solve problems will be greatly improved. 2. Practice of cultivating students' innovative ability with extracurricular scientific and technological activities as the carrier 2. 1 Improve the system and institutions to provide solid guarantee. Perfecting institutions and systems is not only conducive to activities to follow, but also provides strong policy support for activities. In 2006, in order to strengthen the leadership of college students' scientific and technological innovation activities, the school established the leading group of college students' scientific and technological activities and the expert steering Committee of college students' scientific and technological competition, which was responsible for the overall planning and macro leadership of college students' scientific and technological innovation activities. In addition, around the working mechanism of students' scientific and technological activities, the school has also issued a series of management measures suitable for students' scientific and technological activities, such as the Measures for the Management of Subject Competition, the Measures for the Implementation of Credits in the Second Classroom, and the Measures for the Management of Students' Scientific Research Fund. In order to ensure the stable and sustainable development of extracurricular scientific and technological activities, the school has set up a scientific and technological innovation fund for college students, and allocated special funds every year for students to participate in various scientific and technological innovations, inventions and achievements. 2.2 Build a platform, form a team and create a strong atmosphere. At present, the school has formed a working system with the "Challenge Cup" scientific research competition as the leader, the academic and scientific societies of students at both levels of the school as the support, the emphasis on strengthening the construction of teachers, the mass popular science activities and students' application for extracurricular scientific research funds as the basis, and the "Science and Technology Culture Festival" as the main body. The application of students' extracurricular scientific research fund projects is becoming more and more mature, and it has become a large-scale and influential student academic brand activity in our school. Strengthening the brand building of academic scientific and technological associations is the support for developing scientific and technological activities. The Youth League Committee of the school has made the academic associations grow and develop through effective means such as selecting the top ten associations, inclining funds and increasing guidance. This has well stimulated students' awareness of scientific research and enthusiasm for participation, and created a strong academic atmosphere in the whole school. 2.3 Building a system, combining schools with enterprises, and forming a linkage mechanism. According to the knowledge structure, grade characteristics and learning needs of students in various colleges, our school has gradually built a targeted, diversified and flexible student training system on the basis of combing and integrating curriculum design and various scientific and technological activity systems. In order to let students go out of the campus and take the initiative to go to the society, our school closely combines academic research with social development, and forms a linkage mechanism with schools and enterprises. School-enterprise joint training is a market-oriented and social demand-oriented operation mechanism, and schools and enterprises participate in the process of student training together. 3. Thinking of cultivating students' innovative ability with extracurricular scientific and technological activities as the carrier

In the face of the gratifying achievements of students' extracurricular scientific and technological activities, through a comprehensive analysis of the practice of cultivating students' innovative ability with students' extracurricular scientific and technological activities as the carrier, the author believes that in order to continue to deepen this activity and make extracurricular scientific and technological activities really play a role in cultivating innovative talents, the key points are as follows:

3. 1 Establish a target management system for extracurricular scientific and technological activities of college students, and implement target management for scientific and technological activities. Establish a three-level target management system structure of far, medium and near, and improve the effectiveness and pertinence of scientific and technological activities. 3.2 Scientific research should be gradually introduced into many aspects of university teaching to guide students to participate in scientific research. It is necessary to attract students to participate in the teaching reform and construction of the laboratory, develop new scientific and technological experimental bases for students, and realize the joint research between students and teachers. 3.3 fully mobilize the enthusiasm of teachers, teachers are highly motivated, energetic and interested, which also plays a good role in encouraging and promoting students themselves. It is necessary to formulate corresponding incentive measures, support teachers to guide students' scientific and technological activities, encourage teachers to choose outstanding students to participate in their own scientific research projects, and improve the success rate of winning prizes. 3.4 Fully mobilize students' enthusiasm, evaluate students' scientific research and innovation ability, and issue "Statistical Monitoring Index System for Extracurricular Scientific and Technological Activities of College Students and Cultivation of Innovative Quality", taking the consideration of students' scientific and technological activities as one of the important bases for measuring college students' work and selecting outstanding students.
