| Abstract: | The paper statistially analysised the productivity of five species main grain crops at seven counties in the different type regions, the loess plateau.Varied corn’s maximun potential productivity (Ymp) was calculated by agriculture ecology way, which is recommend by FAO.Based on the investigation and compared analysis, the main factor of liminting Ymp and the approach of realizing Ymp were given out.These are the scientific reasons for increasing crop productivity. |
