摘要
为筛选出适合豫中南夏玉米区高产优质多抗的青贮玉米品种,以20个玉米品种为试验材料,对其生育期、干草产量等13个指标进行分析。结果表明,京科青贮516、京科968等6个品种的干草产量较高,抗逆性强。对干草产量、农艺性状及营养指标进行聚类分析,将20个玉米品种分为3个类群,其中,第1类群为京科青贮938等8个品种,其干草平均产量最高,抗逆性强,中性洗涤纤维和酸性洗涤纤维平均最高,饲料相对饲喂价值最低;第2类群为京科522,其农艺性状居于中等;第3类群为MC703等11个品种,其干草平均产量较高,平均粗蛋白含量等营养价值优良。从干草产量等综合分析,MC703、郑单919、京科青贮576、京科青贮516、京科968等5个品种表现较好,适宜作为青贮玉米在豫中南进行推广种植。
In order to select silage maize varieties with high yield,good quality and multi-resistance in south⁃ern summer maize area of central Henan,20 maize varieties were used as experimental materials.Thirteen parame⁃ters,including growth period and hay yield were analyzed.The results showed that,six varieties,including Jingkeq⁃ingzhu516 and Jingke 968,exhibited high hay yield and strong resistance to adverse conditions.Cluster analysis of hay yield,agronomic traits,and nutritional indexes categorized the twenty maize varieties into three groups.The first group,which included eight varieties such as Jingkeqingzhu938,had the highest average hay yield,strong stress re⁃sistance,the highest neutral and acid detergent fiber content,and the lowest feed value.The second group was Jingke522 with medium agronomic traits.The third group was MC703 etc eleven maize varieties which with high av⁃erage hay yield and high average crude protein content.From the comprehensive analysis of hay yield,MC703,Zhengdan919,Jingkeqingzhu576,Jingkeqingzhu516 and Jingke968 showed better performance and were suitable to be used as silage maize in central and southern Henan.
