摘    要:研究了密度对耐密性不同的3个玉米品种主要农艺性状的影响。认为株高、穗位高和穗行数的差异主要来自于品种,密度对其影响较小,在研究密度效应时此3个性状可以不做重点考查;穗长、穗粗、行粒数的差异虽然来自于品种要多一些,但密度的效应加大,在研究密度效应时该3个性状应适当加以考查;倒伏率、空秆率、ASI、秃尖长受密度影响最大,在研究密度效应时应重点加以考查,并且可以做为品种耐密与否的鉴定指标。

关 键 词:玉米  密度  产量

Abstract:The paper studied on the effects on the plant-densities to main agronomic characters of different genotype maize varieties.The conclusions were that plant and ear height and row number difference mainly came from the variety,the density is small to their influence.when research density effect this three characters may not be the key examination;Ear long,ear diameter,row kernel difference although mainly came from the variety,but density effect enlarged,when research density effect this three characters shou...
