摘要: 为筛选出适合黑龙江大庆地区种植和推广的青贮玉米品种,试验对15个青贮玉米品种进行引种品比,研究不同品种鲜重、干重、株高、茎粗、总叶片数、绿叶数、穗位高的指标差异性,并对品种产量与农艺学性状进行相关分析。结果表明:中原单32号和北玉青贮1号2个品种综合表现最好,产量可达63000kg/hm^2以上,穗位高和产量之间呈极显著的正相关关系。该结果可为大庆地区青贮玉米种植和推广提供参考依据。

Abstract: In order to screen the silage maize varieties suitable for planting and popularization in Daqing area of Heilongjiang Province,a total of 15 silage maize varieties were introduced and compared in yield and agronomic traits.The differences in fresh weight,dry weight,plant height,stem diameter,leaf number,green leaf number and ear height between the introduced silage maize varieties were characterized,and the correlation between yield and agronomic traits was analyzed.The results showed that the varieties of Zhongyuandan No.32 and Beiyu silage No.1 had the best comprehensive performance,and both of their yield exceeded 63 000 kg/hm^2.In addition,there was a extremely significantly positive correlation between ear height and yield.This study provides a reference for the cultivation and promotion of silage maize in Daqing area.
