| Abstract: |
| Using the mechanism methodology, climatic-soil potential productivity of corn, rice and soybean was computed according to the factors such as radiation, temperature, precipitation, and soil in each county. At photosynthesis-temperature, the utilization of rice is the highest, 40.6%, and the next is separately soybean 31.4% and corn 27.7%. There is still 59.4% of photosynthesis-temperature resources can be transformated into rice production, while there is even more of those for soybean and corn production, separately 68.6% and 72.3%. At climate, the utilization of soybean is the hignest. At climate a
nd soil, the utilization of rice is the hingest. For different crops, the same natural resources have different satisfaction on plant. The utility rate of photosynthesis, photosynthesis-temperature is not high enough, and there is still climate-soil potential for the productivities of the main crops. Water and soil were probably the main limiting factors. So there is still big potential to tap, and the resource utilization awaits the improvement of of these two aspects in agricultural production process. |
