Agricultural Technology Popularization System In The Micro-level Area Based On Knowledge Flows

Under the background of knowledge economy, agricultural technology innovation is catalyst in the development of modern agriculture to realize industrialization. However the agricultural innovation in China still has the problems of low technical efficiency, the lack of production research use, poor knowledge flow, poor promotion efficiency and so on, and it is urgent to construct the agricultural technology extension system. The existing research on the agricultural technology extension system bias on the macro level of national, less research on the micro level area, more research on agricultural high-tech industries demonstration park, and less research on the general agricultural areas, more less research on the agricultural technology promotion by observing the knowledge flow, and from the point of knowledge flow can identify the role of agricultural extension subject, and tap the key elements of influencing the operation of the agricultural technology extension system. Therefore the research is based on the research in the domestic and foreign literature review, according to the innovation diffusion, the agricultural technology popularization and communication theory, from the research angle of knowledge flows, building the research framework of agricultural technology popularization system in the micro level area, and through the method of combining the form of questionnaire and interview, analyzing in-depth for the case of Lankao county, refining the operating mechanism of agricultural technology popularization system, and finally, it put forward the corresponding suggestions to the construction of agricultural technology diffusion system in Lankao county. Through the study, the following conclusions are drawn:First, from the angle of knowledge flows, the composition of agricultural technology popularization system mainly includes five parts in the micro level area, namely, agricultural technology popularization subject, agricultural technology(the technology inventor is its carrier), technology promotion channels, and technology promotion receptor and the geographic space of the technical communication. In this promotion system, the knowledge flow throughout the entire promotion process, The technology popularization subject pass the explicit knowledge to the receiver of technology by technical training, guidance and other means, after it digested by the receiver of technology, the technology promotion receptor(receiver) combined the explicit knowledge with their own long experience and tips and other tacit knowledge effectively, to achieve the use of new technical knowledge. The new technology popularized spread within the small domain scope, to form the geographical effect of the same technical team, that is, the emergence of professional village or professional town.Second, different promotion subject is corresponding to different ways of agricultural technology popularization; According to the difference of popularization subject, there are four main ways of agricultural technology popularization in Lankao county: the government's leading agricultural technology popularization, enterprise leading agricultural technology popularization, cooperatives leading agricultural technology popularization and the family farm leading agricultural technology popularization. Agricultural technology promotion channels mainly include five kinds, administrative channel, market channel, organizational channel, relational channel, and joint channel. Different method of promotion has different combination of promotion channels. The four agricultural technology promotion ways in Lankao county which is corresponded to the promotion channels mainly include four kinds, administrative channel, market channel, relations channel and joint channel.Third, it has both differences and similarities for the four ways of agricultural technology popularization in Lankao county; The specific differences are expressed in different popularization subject, popularization process and popularization technical nature. The common points are as follows: One is that the leader of higher academic level has more broad-minded, and it is easy to grasp on the technology relatively, more sensitive to grasp on the market; The second is that the object of technology adoption are both farmers, farmers are the group that the most concerned to agricultural production efficiency in agricultural production, due to the limited ability of knowledge, so it is most urgent eager to obtain information of technical knowledge; The third is that they are all good at using the internet to obtain information access to the technical knowledge acquisition channels; The fourth is that this four types of promotion as a whole each can constitute a complete system of promotion on the whole.Fourth, the agricultural technology promotion in Lankao county present a clumped adopted phenomenon in geography. The technology of characteristic planting also showed the phenomenon of cluster adopted in the geographic space. and it leads to the characteristic planting industry of Lankao county showed layout features of regional specialization in the whole geographical space.Fifth, the agricultural technology extension system is running continuously under the effect of internal power and external power. The knowledge flow is the inherent power of agricultural technology extension system, the support of government and the demand pull of market and environmental factors are the external power of agricultural technology extension system. the receptor of technology extension in different cognitive levels has the different acceptance ability on the knowledge of technology, the receptor of lower awareness level need to receive more technical training to master the technology when they accepted technical knowledge, the smaller that the difference of knowledge potential energy between the technology promotion subject and the receptor, the more beneficial to the spread of agricultural technology, in the promotion process, the endogenous capacity of technology receptor increased, external thrust is also constantly enhanced, knowledge can be digestion and absorption.There are two innovations of this study: first, constructed the theoretical framework of the micro regional agricultural technology extension system from the perspective of knowledge flow; second, the framework bring spatial dimension of geography into the framework of agricultural technology extension system, and it combined knowledge spreading with agricultural technology popularization, and by introducing the related concept and connotation of the multidimensional adjacent to explain the geographical space effect of the dissemination of agricultural technology, geospatial dimension into the framework of agricultural technology extension system.
