Abstract: In order to strengthen the application of physics technique in agriculture modernized,this text combining the feature of physical technique, compend the application of physics technique in modem agriculture manufacture, from raising crops yield, processing and reservioring food, monitoring and forecasting on agriculture. At the same time, the physical feature from mechanics, heating, electricity of agriculture mechanization, expounding tremendous action on raising level of agriculture modernized by adopting physics technique.finally propose the prospect of useful foreground of physical technique on agriculture.
