甘肃东部地区8个青贮玉米品种的综合筛选与评价
Comprehensive screening and evaluation of eight silage maize varieties in eastern Gansu Province
摘要
Abstract
The experiment was to select high-yielding and high-quality forage corn varieties suitable for the eastern Gansu Province.Eight silage maize varieties were used as materials,and their agronomic traits,yield traits,and nutritional quality were systematically measured and comprehensively evaluated.The results showed that Yufeng 309 had the highest fresh forage yield and hay yield,which were 74.58 t/hm2 and 32.07 t/hm2,respectively,with the best performance in plant height,ear height,and green leaf number.Lianchuang 902 achieved a hay yield of 28.65 t/hm2,with the highest starch content,relatively high crude protein content,and low fiber content.Zhongkeyu 613 exhibited good overall performance across all traits.Correlation analysis revealed that hay yield was significantly or extremely positively correlated with plant height,stem diameter,ear height,leaf number,green leaf number,and dry matter content(P<0.05 or P<0.01).Crude protein,starch,and crude fat contents were all extremely positively correlated with each other(P<0.01),and hay yield was positively correlated with crude protein,crude fat,and starch.Membership function comprehensive evaluation indicated that Yufeng 309,Lianchuang 902,and Zhongkeyu 613 ranked the top three in overall performance,outperforming the other tested varieties.The study shows that the silage maize varieties Yufeng 309,Lianchuang 902,and Zhongkeyu 613 are suitable for popularization and cultivation in eastern Gansu Province,and can provide high-quality forage options for raising herbivores in this region.关键词
