Abstract:The findings of the research show that during the corn growth, irrigation and K2O can obviously accelerate its corn ear leaf in its chlorophyll content, photosynthesis intensity. And the grouting of its seeds and the final seed yield are also. Certain interaction exists between irrigation and K2O. The perfect usage quantity of K2O is 90 - 135 kg/ha.
Keywords:Irrigation  K2O  Corn ear leaf  Photosynthesis  Yield
