| Abstract: | The diffusion environment of agri-technique is a synthesis of various external factors that affect the spatial diffusion of agricultural technology in a certain temporal-spatial scope.It has a series of features,such as regionality,heterogeneity,dynamics,systematics and so on.Because of these features,the diffusion environment of agri-technique not only affects the direction and speed of spatial diffusion of agricultural technology,even becomes obstacle of spatial diffusion and affects the actual results fi... |
