摘要:
以3 个青贮高油玉米品种为试验材料, 研究了3 种种植密度对青贮高油玉米生物产量、干物质产量及相关性状的影响。结果表明, 不同品种之间生物产量和干物质产量差异极显著, 不同密度下的生物产量和干物质产量差异极显著, 品种与密度互作之间差异显著;龙育1 号、高油169 和高油 115 分别在7.0 万株· hm -2 ～ 8.0 万株· hm-2 、7.0 万株· hm -2和6.0 万株· hm -2 下作为优质青贮高油玉米可在黑龙江省种植推广, 青贮高油玉米品种的青贮生育日数、株高、穗位、茎粗、收获期绿叶片数差异不大, 品种之间差异主要由品种自身特性决定。
Abstract:
Effects o f three kinds o f planting density on biomass , dry matter yield and rela ted traits of three silag e-hig h o il maize cultiv ars were studied. The results indica ted that there w as ultra-sig nificant difference in biomass and dry ma tte r yie ld betw een different cultiv ar s o r different planting density. Under the conditio n of interactio n between cultivar s and planting densitie s, the difference in biomass and dry matter yield w as significant and ultra-sig nificant , respective ly. The pla nting density of Longy u 1, Gaoy ou 169 and Gaoy ou 115 achieved 70 thousand plants to 80 thousand plants per hm2 , 70 thousand plants per hm2 and 60 thousand plants pe r hm2 , respec tively , which sho uld be ex tended as hig hquality hig h-oil silag e maize cultiva rs in Heilo ng jiang province. There wer e little diffe rence in gr ow th pe riod , plant heig ht , ear site , stem diame te r and green-leaf number a t harv esting time between diffe rent silag e-high oil maize cultiva rs. The differences between cultiv ars we re mainly decided by their ow n cha racteristics
