我国农业科技成果转化率长期偏低(40%左右)的原因之一,是农业科技推广存在诸多障碍。以农业技术、物资、品种为主要内容的农业科技推广,是科学技术和文化传播活动。在传播五要素(传播者、受传者、信息、媒介、效果)中,媒介作为内容的载体,作为传播的重要环境因素,是沟通传播者与受传者的桥梁。媒介的选择是否良好,在很大程度上影响着农业科技推广的效果。文章通过对目前我国农村科技传播媒介的类型特点、媒介在我国农村科技传播的主要问题,以及影响媒介在农业科技传播过程中发挥作用的主要因素进行分析与综述,提出改善农村科技传播媒介状况的对策和途径。 One of the reasons why the conversion rate of agricultural science and technology achievements in our country is long-term low (about 40%) is that there are many obstacles in the promotion of agricultural science and technology. Agricultural technology, materials, varieties as the main content of agricultural science and technology promotion, science and technology and cultural activities. Among the five elements of communication (communicators, receivers, information, media, effects), media, as a carrier of content, as an important environmental factor of communication, is a bridge between communicators and receivers. The choice of media is good, to a large extent affect the effectiveness of agricultural science and technology promotion. By analyzing the types and characteristics of rural science and technology media in our country, the main problems of media in rural science and technology transmission in our country and the main factors that affect the role of media in the dissemination of agricultural science and technology, the article proposes to improve the situation of rural science and technology media Countermeasures and ways.
