摘要
为了解不同年份以及不同地区玉米青贮的品质,本试验于2016年1月—2020年12月采集东北(黑龙江、吉林、辽宁)、华北(天津、河北、内蒙古、山东)、西北(宁夏、新疆、甘肃)地区的玉米青贮样本4281份,采用化学分析法测定不同地区青贮玉米的水分、粗蛋白质(CP)、酸性洗涤纤维(ADF)、中性洗涤纤维(NDF)、粗脂肪(EE)、粗灰分(Ash)和淀粉含量。结果表明:2016—2020年,东北、华北玉米青贮的DM、淀粉含量逐年显著上升,ADF、NDF含量逐年显著下降,品质明显提升,西北玉米青贮各项营养成分变化较小,品质稳定。
Borui Technology Testing Center collected 4281 samples of corn silage from Northeast(Heilongjiang,Jilin,Liaoning),North China(Tianjin,Hebei,Inner Mongolia,Shandong),Northwest(Ningxia,Xinjiang,Gansu)from January 2016 to December 2020.The laboratory technician use chemical methods to detect moisture,crude protein,crude fat,neutral detergent fiber,acid detergent fiber,ash,starch of corn silage.We can understand the quality of corn silage in different years and regions.The results showed that from 2016 to 2020,the content of dry matter(DM)and starch in corn silage showed uptrend,while ADF and NDF showed downtrend year by year in Northeast and North China,the quality has improved significantly.The nutritional ingredient has little change,the quality has remained stable in Northwest.
