气候、品种和密度对东北春玉米增产潜力的影响

Effects of Climate,Cultivars and Density on Yield Potential of Spring Corn in Northeast of China

近年来,东北春玉米超高产技术研究已经取得了重大进展,但春玉米增产潜力仍有很大空间。本文从3个主要方面探讨了气候、品种和密度对东北春玉米增产潜力的影响,最后提出应深入研究综合因素对玉米增产潜力的影响,获得更具体的粮食生产潜力,并确定哪些因素起主导作用。

In the resent years,studies on super high-yielding of spring corn had made important progress in Northeast of China,but there are great spaces on yields potential of spring corn.From the three major aspects,effects of climate,cultivars and density on yield potential of spring corn in Northeast of China were explored in the paper.It suggested at last that effect of comprehensive factors on yield potential of corn should be deeply studied,and solid yield potential and dominant factors should be made clear.
