[Method] The technology acquisition advantage of social network was il- lustrated by summarizing the status and characteristics of agricultural technology and technology supporting types in the process of agriculture technology diffusion. [Result] The multi-layer, complex, persistence, systematization features of agricultural technol- ogy require support and help of technology from surrounding social network to ulti- mately internalize the technology. [Conclusion] Using social networks for the technol- ogy support will be a powerful supplement to the system of agricultural technology diffusion.展开更多

Promoting smallholder farmers’ adoption of modern agricultural production technology is one effective way to improve the capabilities of smallholder farmers. This paper aims to explore the impact of Internet use on the adoption of agricultural production technology by smallholder farmers based on a survey of 1 449 smallholders across 14 provinces in China. The results suggest that Internet use can significantly promote technology adoption, with the probability of adopting new crop varieties, water-saving irrigation technology and straw-returning technology increasing by 0.200, 0.157 and 0.155, respectively. Furthermore, the effect of Internet use is found to be heterogeneous with a greater effect on smallholder farmers having low education levels, limited training, and high incomes. To increase agricultural production technology adoption by smallholders, rural Internet infrastructure and Internet use promotion should be the focus for the Chinese government.展开更多

The contents, closeness degree and stability of cooperation of them are different. Under different cooperation models, the closeness degree of pillar industry and rural households differs, as well as the speed and effect of the technology promotion. By comparing the situation of technology promotion under the three cooperative models, the results can be obtained. The workshop type can reduce the risks of adopting new technologies of farmers greatly; strengthen the internal motivation of farmers to adopt new technology, so it can attract more farmers. Therefore, the workshop type represents the developmental direction of industrialization of tomato industry in Xinjiang to a certain extent.展开更多

The results show the main factors that influence farmers; behaviors on agricultural inputs are whether they have the assistance of agricultural technology personnel; the choices of plantation; non-agricultural income; area of land management; the expectation on land ownership, whether it has township enterprises and the proportion of the non-agricultural labor forces and some other factors. The influencing degree of these factors descends from strong to weak. On the strength of the study results, the countermeasures on increasing local farmers' inputs on agricultural technology are put forward from the aspects of stabilizing rural land property, establishing scientific land transfer mechanism and intensifying the governmental functions of agro-technical station.展开更多

Runoff water volume (1996-2002), soil loss (1996-2002) and maize yield (1995-2001), and soil fertility-related parameters were assessed on SALT models with three factors: the type of nitrogen-fixing plant, the farmers' practice, and fertilizer use. Results showed a significant effect of Alnus nepalensis and/or Indigofera dosua on runoff water volume, soil loss, crop produc- tion, soil water retention, and soil nutrients (NPK). Farmers' practice and fertilization did not play a significant role in reducing runoff water and soil loss. However, farmers' practice significantly increased crop produc- tion. Therefore, integrating soil conservation approaches on SALT sys- tems enhances stable economic output to hills and mountain farmers.展开更多

Our study uses disaggregated spatial information in its model to analyze ASTP technology diffusion in a heterogeneous space. We constructed a comprehensive index system to evaluate the diffusion environmental quality and introduced the heterogeneous diffusion equation to calculate the technological diffusion probability. We applied this framework to a real-world scenario: the apple planting technology diffusion of the Yangling ASTP in the Loess Plateau, China. The results indicated: (1)the technological diffusion environment of the Loess Plateau advantageous apple producing area showed strong spatial heterogeneity caused by climate, topography, and external transportation links.(2) Under the combined effects of distance and spatial heterogeneity, the spatial diffusion pattern of the Yangling ASTP apple technology was expansion diffusion supplemented by hierarchical diffusion and banded diffusion, and (3) ASTP technology diffusion showed a strong distance attenuation effect, and the frictional effect of distance can be decreased by improving the diffusion environmental quality. These laws can promote regional balanced ASTP-driven development.展开更多

It is an inevitable choice and important way to realize the transformation from traditional agriculture to modern agriculture. This paper reviewed the construction background,functional characteristics and development history of agricultural science and technology parks. It analyzed the current development situations of the provincial agricultural science and technology parks in Jiangyang District,Luzhou City of Sichuan Province. Then,it summarized its experience in park construction and compared with surrounding national and provincial agricultural science and technology parks. It found existing problems including insufficient industry-university-research integration,low level of agricultural intensification,weak functions of public service platforms and brand effect,and insufficient exploration of tourism resources. In view of these problems,it came up with recommendations for development of agricultural Sci-Tech Park District of Luzhou City,including gathering scientific and technological resources,enhancing scientific and technological support,strengthening the high-quality development of the park economy,and building a national 4 A-level excellent scenic spot.展开更多
