摘　　要：为探究复合酶和尿素不同处理对玉米秸秆发酵品质的影响,该试验共分为4个处理组,每组3个重复,对照组(CK)喷洒清水,氨化处理组(Ⅰ组):玉米秸秆+2%尿素,复合酶处理组(Ⅱ组):玉米秸秆+0.5%复合酶,综合处理组(Ⅲ组):玉米秸秆+2%尿素+0.5%复合酶。结果表明,氨化处理组(Ⅰ组)显著提高玉米秸秆粗蛋白含量;复合酶处理组(Ⅱ组)玉米秸秆感观品质最佳,显著降低玉米秸秆的中性洗涤纤维和酸性洗涤纤维含量;综合处理组(Ⅲ组)显著提高玉米秸秆粗蛋白含量、显著降低玉米秸秆的中性洗涤纤维含量。综合评价,复合酶处理组(Ⅱ组)可显著改善玉米秸秆品质,氨化处理、复合酶处理和综合处理均可提高玉米秸秆的营养价值。To investigate the effects of different treatments of compound enzymes and urea on the fermentation quality of corn stover.The trial was divided into 4 treatment groups,with 3 replicates in each group.The control group(CK)was sprayed with clean water,while the ammonification treatment group(Group I)consisted of corn stover and 2%urea;Compound enzyme treatment group(Group II):corn stover+0.5%compound enzyme;Comprehensive treatment group(Group III):corn stover+2%urea+0.5%compound enzyme.The results showed that:the ammonification treatment group(Group I)could significantly increase the crude protein content of corn stover;The composite enzyme treatment group(Group II)had the best sensory quality of corn stover,significantly reducing the content of neutral and acidic detergent fibers in corn stover;The comprehensive treatment group(Group III)can significantly increase the crude protein content of corn stover and significantly reduce the neutral detergent fiber content of corn stover.Overall evaluation shows that the enzyme preparation treatment group(Group II)can significantly improve the quality of corn stover,and ammonification treatment,compound enzyme treatment,and comprehensive treatment can all enhance the nutritional value of corn stover.
