“科学技术是第一生产力”。发展农业,一靠政策,二靠投入,三靠科技,但最终要靠科技来解决。因此,寻求科技投入使农业生产持续、稳定、协调发展已成为一种必然选择。然而由于传统体制的制约,科技与农业生产之间存在着难以逾越的断层,一方面大量的农业科技成果被束之高阁,另一方面农户所需的科技知识却无从获得,由于受各自条件的限制,科技部门与农户都无法弥合这一断层。笔者认为,解决这一断层的主要办法就是建立和完善农业科技服务体系。在这方面,作为 “Science and technology are primary productive forces”. The development of agriculture depends on policy, investment on the 2nd, and technology on the 3rd, but it ultimately depends on technology. Therefore, it has become an inevitable choice to seek scientific and technological inputs to ensure the sustained, stable and coordinated development of agricultural production. However, due to the constraints of the traditional system, there is an insurmountable gap between science and technology and agricultural production. On the one hand, a large number of agricultural science and technology achievements have been shelved. On the other hand, the scientific and technological knowledge required by farmers is not available, due to the constraints of their own conditions. Neither the science and technology department nor the farmers can bridge this fault. The author believes that the main solution to this fault is to establish and improve the agricultural science and technology service system. In this regard, as
