10个玉米群体作为青贮玉米利用价值分析

Analysis of Utilization Potential of Ten Maize Populations As Silage Corn

分析了8个热带群体和2个中国主要种质群体在湖北省黄冈市作为青贮玉米的利用价值。结果表明,中群26、中群28、中群25、中群24和中群11的干物重较高;中群25、中群26和中群24的持绿性较好;中综5号、中综7号、中群11、中群22、中群23和中群28的抗倒性较好;中群27和中群11的中性洗涤纤维含量较低;中综7号、中群23和中群25的酸性洗涤纤维含量较低;中综5号、中群22、中综7号和中群11的粗蛋白含量较高。中群11可以直接作为青贮玉米利用,其余群体在青贮玉米利用的某一方面都具有较好的利用价值,可以作为青贮玉米改良的群体。

Analyze utilization potential of eight tropical and two Chinese maize populations as silage corn in Huanggang city, Hubei province. The results showed that： Cpop.26, Cpop.28, Cpop.25, Cpop.24 and Cpop.ll had higher dry matter; Cpop. 25, Cpop.26 and Cpop.24 had longer period of green leaves; Csyn5, CsynT, Cpop.11, Cpop.22, Cpop.23 and Cpop.28 had stronger lodging resistance; Cpop.27 and Cpop.ll had lower neutral detergent fiber（NDF） content; CsynT, Cpop.23 and Cpop. 25 had lower acidic detergent fiber （ADF） content; CsynS, Cpop.22, Csyn7 and Cpop.11 had higher crude protein （CP） content. In short, Cpop.ll could be directly used as silage corns, other populations could be used to improve specific quality of silage corn.
