摘要:
为研究荒漠灌溉地区青贮玉米农艺性状和发酵品质动态变化规律以及筛选第三师地区最佳青贮玉米栽培品种,选择4个青贮专用和11个粮饲兼用型玉米品种为试验材料,分别在灌浆期、1/4乳线期、1/2乳线期和3/4乳线期进行农艺性状测定并调制青贮饲料。发酵60 d进行青贮饲料发酵品质、营养成分和体外消化测定,以农艺性状、营养成分、发酵品质和消化特征为评价指标,利用相似优先比法对15个玉米品种进行综合评价。结果表明:随生育期推进各青贮玉米株高、穗位、鲜草产量、全株鲜重、茎秆鲜重、果穗鲜重、籽粒鲜重、干物质(DM)、粗蛋白(CP)、可溶性碳水化合物(WSC)、淀粉含量和代谢能(ME)不断递增,到3/4乳线期达到峰值;其中,3/4乳线期大丰30鲜草产量最高,金玉9号DM含量最高,新饲玉10号CP含量最高,先玉696 WSC含量最高,屯玉765淀粉含量最高,均与其他品种差异显著(P<0.05)。随生育期推进,中性洗涤纤维(NDF)、酸性洗涤纤维(ADF)含量、氨态氮∶总氮(NH3-N/TN)、有机物消化率(OMD)和产气速率不断递减,ADF、NDF、NH3-N/TN在3/4乳线期达到最优,其中,3/4乳线期新饲玉12号ADF含量最低,新饲玉10号NDF含量最低,新饲玉11号NH3-N/TN最低,均与其他品种差异显著(P<0.05);OMD和产气速率在灌浆期最优,其中,先玉696 OMD最高,新饲玉10号产气速率最高,均与其他品种差异显著(P<0.05)。随生育期推进各玉米品种pH值先降低后升高,乳酸(LA)含量先升高后下降,乙酸(AA)和丙酸(PA)无明显变化规律。pH值在1/2乳线期达到最优,最优品种为屯玉765,LA在1/4乳线达到最高,最优品种为新饲玉12号,均与其他品种差异显著(P<0.05)。综上所述,在3/4乳线期收获能获得高产优质的青贮玉米,新沃1号、屯玉765和大丰30综合价值较优,适宜在第三师地区及相似生态区域推广种植。
