摘  要：
对在山西高寒冷凉区种植面积较大的30个粮饲兼用型玉米品种(以永玉3号为对照)进行鲜产量、品质、抗性等的综合评价,结果表明30个参试品种中鲜产量比永玉3号增产的有12个品种,其中达到显著水平的有2个品种。子粒产量比永玉3号增产的有14个品种,其中达到显著水平的有8个品种。品质分析结果表明有6个品种的总可消化养分量比永玉3号高(1.0%～3.0%),分别为豫青贮23、晋单65号、先玉508、文玉3号、大丰26号和金岭青贮10号。综合不同指标的相关分析结果,在全株玉米干物质含量为30.0%～35.0%、子粒乳线百分比为40.00%～50.00%时为最佳收获期。

摘  要：
Comprehensive evaluation of 30 grain and forage maize varieties with large planting area in high latitude and cold region of Shanxi Province was conducted, which included silage fresh yield, quality, resistance. The results showed that fresh yield of 12 varieties was increased compared with the control Yongyu 3, and all reached a significant level(P <0.05) and 6 varieties reached at extremely significant level(P <0.01). The grain yield of 12 varieties was increased and all reached a significant level compared with Yongyu 3, and 2 varieties reached extremely significant level. Quality analysis results showed that the total digestible nutrient content of the 6 varieties were increased by 1.0% to 3.0% than Yongyu 3, including Yuqingzhu 23, Jindan 65, Xianyu 508, Wenyu 3, Dafeng 26 and Jinlingqingzhu 10. According to the correlative analysis of different indexes, it is suggested that the best harvest time is 30.0% to 35.0% of dry matter content and 40.00% to 50.00% of grain milk line in the whole maize plant.
