摘　　要：为解决当前饲养牛、羊等动物冬春季节饲草料短缺、降低饲草料成本、扩充牧草资源等问题,以冬牧70黑麦草为对照,比较5个饲料油菜品种与对照品种不同时期干鲜比、生物产量、营养成分,研究饲料油菜作为冬春季节青饲料相较于黑麦草优劣势。结果表明,两种不同刈割方式下饲料油菜平均生物产量比冬牧70黑麦草高183.92%;饲料油菜与黑麦草年平均干草产量分别是1.49 kg·m^(-2)和0.53 kg·m^(-2),饲料油菜年平均干草产量是黑麦草的2.81倍;牲饲1号和牲饲2号粗蛋白含量高达25.86%、26.92%(干基蛋白),比冬牧70黑麦草高7%~10%。研究表明,牲饲1号和牲饲2号在3个评价指标上与冬牧70黑麦草相比具有较大优势,可以作为一类新型优质动物饲草。In order to solve the grass shortage of animals such as cattle,sheep hours in the winter and spring were,to reduce the hours to purchase cost,expand the forage resources,this experiment ryegrass was controlled,of five feed rapeseed varieties and check varieties in different periods of biological yield,plant height,stem fresh than,nutrients,to explore the advantages and disadvantages of rapeseed as animal forage in winter and spring compared with ryegrass.The results showed that the average biological yield of two different cutting methods was 183.92%higher than that of 70 ryegrass.The average annual hay yield of rapeseed and ryegrass was 1.49 kg·m^(-2) and 0.53 kg·m^(-2) respectively.The annual hay yield of rapeseed was 2.81 times that of ryegrass.The crude protein content of Shengsi No.1 and Shengsi No.2 was as high as 25.86%and 26.92%(dry base protein),which was 7%~10%higher than that of ryegrass.The experimental results showed that Shengsi No.1 and Shengsi No.2 had great advantages over ryegrass in growth,yield and forage quality,and could be used as a new kind of animal forage.
