Abstract
Silage corn is one of the main sources of forage for herbivorous livestocks.Due to the differences in varieties,plant types,and ecological regions of cultivation,the suitable planting density variesac cordingly.To screen out therational planting density of different silage corn varieties in the Wuwei,experiments were conducted on the introduced silage corn varieties Yayu 26 and Wugu 8818.The results showed that both Yayu 26 and Wugu 8818 had uniform field growth and lodging resistance at a planting density of 90 000 plants/ha,with the highest yields of fresh and hay biomass recorded,which were 82 600.5 and 75 883.5 kg/ha,and 30 060.0 and 28 369.5 kg/ha,respectively.The most suitable planting density for silage corn Yayu 26 and Wugu 8818 in the Wuwei is 90 000 plants/ha.关键词
