摘    要:以3个青贮玉米品种龙育6号、高油115和中原单32为试验材料,研究了5种种植密度对青贮玉米生物产量、干物质产量及相关性状的影响.结果表明:青贮玉米株高和穗位高随密度的增大而增高,绿叶片数随密度增大而减少,但差异不显著;随密度的增大,田间倒伏(折)逐渐严重,生育日数略微延迟.不同品种之间倒折有差异.不同类型青贮玉米品种生...

关 键 词:青贮玉米  种植密度  产量  相关性状

Abstract:Taking three silage maize cultivars of Longyu No.6,Gaoyou 115 and Zhongyuandan 32 as experimental materials,the effect of 5 different planting densities on biomass,dry matter weight and related traits was studied.The results indicated thatthe height of plant and position of silage maize increased with the increasing of planting density,on the other hand,the amount of green leaves were decreased with the increasing of plant density but the difference were not significant;The lodging of maize under heavy dens...
Keywords:silage maize  planting density  yield  related traits
