摘　　要：为探讨玉米秸秆青贮饲料营养物质随时间变化规律,选取生长期为105 d的青玉米秆调制青贮饲料,50 d后开窖,考察了青贮饲料在50~290 d贮存期间7种主要营养物质随时间的变化规律。研究了营养物质与贮存时间以及纤维类成分与干物质之间的相关关系,并建立了一元回归模型。In order to ensure the better utilization of corn straw silage, the variation law of corn straw silage nutritional quality uiner different storage periods was studied. The corn stalk was harvested and ensiled when the grow period reached the 105th day. Seven chemical components of corn straw silage at different storage times from 50 to 290 days were analyzed. The relationship between chemical components and storage periods was studied and the single-element regression models were built. This research achievement can provide scientific basis for rational utilization of silage.
