基于小麦良种的农业技术创新扩散研究

大量农业技术创新能否及时有效地实现扩散直接关系到区域农业的快速进步,但我国目前对农业技术创新空间扩散过程的研究相当缺乏。以杨凌农业示范区作为创新源头,以小麦良种—小偃22作为创新技术,以陕西关中地区作为扩散区域,构建了小麦良种技术扩散的模型,并对其空间扩散的特征、模式与机制进行了分析。研究结果表明：示范强度、种植规模、种植条件、技术本身的优势等与扩散过程呈正相关;扩展扩散与等级扩散相结合是主要的扩散方式;扩散机制则表现出以政府为主导的联合驱动。图3,表2,参11。

An Empirical Study on the Spatial Diffusion of Agricultural Technology Innovation-a Case of Wheat-seed

Efficient and prompt diffusion of agri-technique innovation directly influences the rapid growth of district agriculture.Unfortunately,so far in our country,research on spatial diffusion process of agri-technique innovation is inadequate.Taking Yangling National Agriculture High-tech Industries Demonstration Zone as a source of innovation,with its surrounding areas Guanzhong as diffusion region,the diffusion model of the wheat-seed technology was constructed,and its spatial diffusion characteristics,patterns and mechanisms are analyzed.The results showed that model intensity,the scale of planting,cultivation conditions and the advantages of the technology itself,were positively correlated with the process of diffusion.Expansion diffusion combining with grade diffusion is the main way of the diffusion of wheat-seed technology.The role of government is the main mechanism of diffusion.
