| Abstract: |
| The productive potential of photosynthesis, light-temperature, climate and climate-soil resources is analyzed for the main crops in Sandaogou, Arong county, Hulanbeier city, Inner Mengolia. The results show that heat energy is the main uncontrollable factor that limits the production of crops in this area, and the yield can be increased by 20%30% if the thermal condition is improved. The sufficiency rate of rainfall to the main crops is 80% or so, showing that the amount and seasonal distribution of rainfall is one of the factors that limit the production. The soil nutrients condition does not remarkably limit the productivity of potato and rice, but it is a main limiting factor to the productivity of corn and soybean. |
