Abstract: From the point of view of sustainable development, it is vitally important for Chinese agriculture to implement five technology development strategies and strengthen technical study of four fields. In the more specific terms, they are as follows: implementing resources substitution strategy and strengthening technical study for overcoming agricultural resources scarcity, implementing high-tech strategy and strengthening technical study for overcoming empirical agriculture instability, implementing common techniques upgrading and fields spreading strategy and strengthening technical study for overcoming low agricultural profitability and efficiency, and implementing ecological security strategy and strengthening technical study for overcoming agricultural insecurity. Above four fields together compose the technology support system for Chinese agriculture sustainable development. At last, the key techniques contained by each field are elaborated and these techniques should be properly integrated in order to push Chinese agricultural sustainable development.
