Abstract:

The production performance and adaptability of 13 silage corn varieties were evaluated in Haihe plain. The experiment results indicates that the dry-grass yields of ‘BeinongQZ308’,‘YuQZ23’,‘HuaiyanQZ6’,‘BeinongQZ1’ and ‘BeinongQZ208’ were higher than the control variety ‘Zhengdan958’, and dry-grass yield of ‘BeinongQZ308’ achieved 17674.9 kg·hm-2 which was the highest, 9.0% more than ‘Zhengdan958’. In the aspects of quality evaluation, using Relative Feeding Value (RFV)、Forage Grading Index (GI) and Subordination Function Method(SFM)to evaluate the forage quality of testing varieties, ‘XunqingQZ938’, ‘XunqingQZ518’, ‘BeiQZ1’ and ‘YuQZ23’ had good forage quality by comprehensive analysis. ‘BeinongQZ308’,‘BeinongQZ208’,‘BeiQZ1’ and ‘ZhongbeiQZ410’ had higher Water Use Efficiency (WUE), belongs to the water-saving varieties. We had set the screening criteria of varieties, which were infected rate less than 5% (sum of head smut and corn smut) and lodging rate less than 15%.‘BeiQZ1’, BeinongQZ208’ and ‘BeinongQZ308’ were comprehensive screened out and were suitable for planting in Haihe plain.

摘要:

通过田间试验对13个青贮玉米(Zea mays)品种在海河平原区的生产性能及适应性进行了评价研究。结果表明:产草量方面,‘北农青贮308’、‘豫青贮23’、‘怀研青贮6号’、‘北青贮1号’、‘北农青贮208’干草产量高于对照‘郑单958’,其中‘北农青贮308’产量最高,为17674.9 kg·hm-2,增产幅度达9.0%。饲用品质方面,对不同品种的粗蛋白含量、淀粉含量、可溶性总糖含量、酸性洗涤纤维、中性洗涤纤维进行了分析比较,利用相对饲用价值(RFV)、饲草分级指数(GI),隶属函数法分别进行了综合评价,得出品质优于对照的品种为‘青贮巡青938’、‘青贮巡青518’、‘北青贮1号’、‘豫青贮23’。节水性方面,‘北农青贮308’、‘北农青贮208’、’北青贮1号’、‘中北青贮410’具有较高的水分利用效率,属于节水型品种。抗逆性方面,规定倒折率高于15%,瘤黑粉、丝黑穗病株率之和大于5%作为品种淘汰界限。综合评价筛选出适于在海河平原种植推广的青贮玉米品种为‘北青贮1号’、‘北农青贮208’和‘北农青贮308’。
