[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

文摘制种基地和时段的选择是两系杂交稻制种成败的关键,根据历史气象资料和制种不同时段对气象条件的要求确定两系杂交稻种子生产的适宜气候区域与时段能够为两系杂交稻制种提供决策支持。运用可视化编程工具Visual Basic 6.0,通过对气象站点的温度、降雨量、湿度等历年气象资料进行预处理,借助于XML进行合理的存储,将地理信息系统(Geographic Information System,GIS)集成二次开发的思想应用于可视化编程中,设计开发了两系杂交稻制种基地气象决策支持系统。利用湖南省50a的气象资料,依据该系统确定了湖南省两系杂交稻制种的适宜区域与时段。结果表明,决策系统运行结果与实际情况相符,系统具有较好的决策功能。该系统可为两系杂交稻的高产高效安全制种提供强有力的技术支撑。
