(1) In organizational system,rural sci-tech service associations should become nonprofit organizations that have independent legal entities. (2) In service object,it should take farmers as subject,new rural economic organizations as carrier,agricultural leading enterprises as handle,little village officials as joint,sci-tech special commissioner as link,and agricultural brokers as medium. (3) In information resources,it should enhance practicality construction and sharing. (4) In service methods and reform measures,it should combine information technology,expert technical consulting service,and sci-tech model base. (5) In policy support and input mechanism,it should follow the principle of diversification,set up government special funds,and formulate preferential policies to attract sci-tech talents to join in rural sci-tech services,and protect legal rights and interests of sci-tech personnel in rural sci-tech services.展开更多

With reference to the concept of modern commodity supermarket, this model integrates variety, technology and achievement information into the sci-tech supermarket platform, provides various agricultural sci-tech services, and improves farmers recognition and acceptance of science and technology, so as to accelerate conversion of scientific and technological achievements and demonstration and popularization of new varieties, new technologies and new models. This paper analyzes practice of Jurong economic forest and fruit industrial branch and presents recommendations for building Jiangsu rural sci-tech service supermarket.展开更多
