| Abstract: | This paper had done the studies on the effects of the potassium fertilizer on maize photosynthetic characteristics,grain filling characteristics and yield under the potassium supply state.The result showed that the fertilization of K2O could obviously accelerate corn ear leaf in its chlorophyll content,photosynthetic intensity.And the grouting of its seeds and the final seed yield was also.The perfect usage quantity of K2O is 90-135 kg/ha. |
