适宜山东菏泽地区种植的全株青贮玉米品种筛选试验

山东省菏泽市及周边地区玉米种植广泛,全株玉米青贮用于养殖牛羊越来越多,为选择出高产优质全株青贮玉米品种,采取随机区组设计,从多个玉米品种中选择7个进行种植试验,对各品种收获期、株高、鲜重、干重、粗蛋白质含量等生产性能和营养指标进行测定。从筛选试验结果来看,渝青386号植株高大、双果穗多、果穗饱满,抗逆性好,可消化营养物质含量高,干物质产量达到18402.67 kg·hm^-2,收割时粗蛋白质含量为8.59%,适合菏泽市及周边地区青贮玉米种植。玉米品种奥玉5102号、先禾518号和大京九4059号也相对较好。

Selection of Whole Silage Corn Varieties Suitable for Planting in Heze Area

Extensive corns are planted in Heze City and its surrounding areas.More and more whole plant corn silage are used to feed cattle and sheep.In order to select high-yield and high-quality silage corn varieties,we used random block design and selected 7 qualities from multiple corn varieties for planting experiments to determine their production performance,nutritional indicators of each variety at harvest time,plant height,fresh weight,dry weight,and crude protein content.The results showed that Yuqing 386 was high,had double fruit ears,full fruit ears,strong stress resistance,high digestible nutrients,and a dry matter yield of 18402.67 kg·hm^-2.At the time of harvest,its crude protein content got 8.59%,was variety for silage corn planting and utilization in Heze and its surrounding areas.Aoyu Maize No.5102,Xianhe No.518 and Dajingjiu No.4059 were also relatively good.
