摘　　要：通过大田试验,采用方差分析法对冬牧70黑麦5个不同播种量的鲜草和干草产量进行比较分析,并对5个不同播种量的冬牧70黑麦生育时期及群体动态进行了综合评估。结果表明,在宁夏地区冬牧70黑麦适宜播种量为180~225kg/hm^2。该播种量范围,冬牧70黑麦鲜草和干草产量高,群体结构合理,越冬存活率较高,个体发育充分,综合性状较好。In order to select right seeding rate of Dongmu 70(Secale Cerale) in Ningxia, the fresh weight and dry weight performances were compared and analyzed by variance analysis. Stages and population dynamics of 5 processings were investigated. The results showed that the appropriate seeding rate of Dongmu 70(Secale Cerale) in Ningxia was in the range of 180~225 kg/hm^2. In this range, the fresh weigh and dry weigh were the highest, the population structure was reasonable,overwinter survival was higher, the individual's development was favorable, and the comprehensive characters were better.
