摘要
【目的】对不同青贮玉米品种的农艺性状及营养价值进行分析,为筛选适合云南省保山市种植的优质青贮玉米品种提供一定的理论参考。【方法】对10个青贮玉米品种乳熟期的株高、鲜质量和干质量等8个形态指标进行观测,同时将全株青贮玉米切碎青贮60 d后测定粗蛋白、粗脂肪和粗灰分含量等9个营养价值指标;采用隶属函数进行综合评价。【结果】云端10号的穗长、穗围、茎质量、鲜质量和干质量均显著高于其他品种(P<0.05);迪卡667的水分含量显著低于其他品种(P<0.05),其粗灰分、粗脂肪和粗蛋白含量均高于或显著高于其他品种(P>0.05或P<0.05)。通过隶属函数分析得出适合种植的顺序为云端10号>西抗18>云青2号>禾玉9566>迪卡667>金科932>云青5号>大天一号>中玉335>奥玉5102。【结论】综合评价认为云端10号、西抗18和云青2号较适合在云南保山地区推广种植。
[Purpose]To analyze the agronomic traits and nutritional value of different silage maize varieties,so as to provide some theoretical reference for screening the high quality silage maize varieties to be popularized in Baoshan City,Yunnan Province.[Methods]Eight morphological indexes,such as plant height,fresh weight and dry weight,were measured in 10 silage maize varieties at milk ripe stage.Nine nutritional values,such as crude protein,ether extract and crude ash content,were determined after the whole silage corn chopped up for 60 days,and membership function was used for comprehensive evaluation.[Results]Ear length,ear circumference,stem weight,fresh weight and dry weight of Yunduan No.10 were significantly higher than those of other corn silage varieties(P<0.05),while water content of Dika667 was significantly lower than that of other maize silage varieties(P<0.05),and the crude ash,ether extract and crude protein contents of Dika667 were higher or significantly higher than those of other maize silage varieties(P>0.05 or P<0.05).Through membership function analysis,the suitable planting order was Yunduan No.10>Xikang18>Yun-qing No.2>Heyu9566>Dika667>Jinke932>Yunqing No.5>Datian No.1>Zhongyu335>Aoyu5102.[Conclusion]The comprehensive evaluation shows that Yunduan No.10,Xikang18 and Yunqing No.2 are suitable for planting in Baoshan area of Yunnan Province.
