玉米种植方式有两种。一是等行距种植，是目前玉米主要种植方式。其优点是在玉米抽穗前，地上部叶片与地下部根系在田间分布均匀，能充分利用养分和阳光；播种、除草都便于机械化作业。缺点是在肥水高、密度大的条件下，生育后期行间郁蔽，光照条件差，通风不好，光合使用效率 There are two ways to grow corn. First, the line spacing planting, is the main way of planting corn. The advantage is that before the corn is erupted, the roots of the above-ground leaves and the underground part are evenly distributed in the field and can fully utilize the nutrients and sunshine; the planting and the weeding are all convenient for the mechanized operation. The disadvantage is high in fertilizer and water, under the conditions of high density, dark lines between the rows after the birth, poor lighting conditions, poor ventilation, photosynthetic efficiency
