| The Potentials and Approaches of Grain Production Development in North Shaanxi and Weibei Region |
|

| Abstract: |
| The significance of grain production development in North Shaanxi and Weibei Region is discussed.The increasing potentials of sowing acrages,yield per hactare and annual total yield of grain crop in the two regions are analysed quantitively.The results show that the maximum annual total grain yield in the two regions can rearch 7850 million kg and that the increment of annual total grain yield based on avrage of the period from 1991 to 1995 is 4367 million kg. The approaches and the requiremant for grain production development are also analysed in the end. |
