随着玉米生产水平的不断提高 ,玉米的种植密度越来越大 ,高产再高产给玉米品种的耐密性提出了更高的要求。所谓的品种耐密性就是指某个玉米品种在较大群体下具有的较高的单株生产力 ,且对不同群体密度反应的迟钝性。近年来 ,有关玉米耐密性的研究较多 ,但对如何将耐密性进行数 With the continuous improvement of the corn production level, planting density of maize is more and more high yield and then high yield of corn breeds put forward higher requirements. The so-called breed tolerance refers to the higher individual productivity of a certain corn variety in larger populations and the insensitivity to the density response of different populations. In recent years, there have been many researches on the confinement of corn, but how to conduct the confidentiality of maize
