摘要： 以内单402，内单302，四单19号，哲单7号四种玉米品种为试验材料，在地处黄土高原北部的内蒙古准格尔旗进行玉米灌浆速率测定。结果表明，吐丝后相同时间，四单19号和哲单7号的籽粒含水量较内单302和内单402高，百粒干重较低，而灌浆高峰出现明显偏早。根据这些规律，可选栽适合当地气候特点的玉米品种。

Abstract: In this paper, the four varieties of maize were used as material to research the filling rate in Zhungeer, which located on north of loess plateau. The result showed that the water contents of seed of Sidan 19 and Zhedan 7 were higher than that of Neidan402 and Neidan302, and the weights of seed of Sidan 19 and Zhedan 7 were lower than that of Neidan402 and Neidan302 after spinning. The highest rate of filling of Sidan 19 and Zhedan 7 were earlier than that of Neidan402 and Neidan302. Based on these reasons, the optional variety was selected to adapt to the regional climate.
