摘要: 在玉米生育期间进行灌水和施用钾肥,对玉米果穗叶片的叶绿素含量、光合强度和玉米籽粒灌浆及最终的籽粒产量均有明显的促进作用;灌水与施用钾肥之间有一定的互作效应;钾肥(K2O)的适宜施用量在90~135 kg/hm2为宜。

关键词: 灌水, 钾肥, 玉米果穗叶片, 光合特性, 产量

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.

Key words: Irrigation, K2O, Corn ear leaf, Photosynthesis, Yield
