- Abstract:
- Crop productivity is an important factor that measurces social-economic conditions and eco-environmet of a region. The history、present situation and limited factors of crop produvtivity have been analysed. On basis of agroecological methods recommeded by FAO, the maximum and rainfall potential productivity of main crops has been calculated. And based on the study on correlation between grain productivity and some ecological-economic factors, the measures and suggestion of raising crop productivity have heen put forward.
