针对基因操作较为抽象,园艺专业本科生生物技术系统知识不强、动手能力较弱的问题,通过3年时间,设计了3个不同内容和层次的基因工程实验,提高了学生的学习兴趣和动手能力以及创新能力,并对开放实验的效果和存在的问题进行了思考。 For three years, three gene engineering experiments with different contents and levels were designed to improve the students’ interest in learning and hands-on activities. In view of the fact that genetic manipulation is more abstract and horticultural undergraduates have less knowledge of biotechnological systems and weak hands-on ability, Ability and ability to innovate, thinking about the effect and existing problems of open experiment.
