摘　　要：为探明冬牧70黑麦在宁夏地区适宜的株高收获期,通过大田试验,采用方差分析法对不同株高收获期的鲜草、干草产量进行比较分析,并对各处理的营养品质含量及产量和营养品质指标的综合分析结果进行了评估。结果表明,宁夏地区适宜收获的株高范围为90~150cm,对应时间为5月4-16日,即:抽穗至开花期,此时鲜草和干草产量高,粗蛋白(CP)含量较高,中性洗涤纤维(NDF)含量适中,综合性状良好,适合饲喂牛、羊等反刍动物。收获后可以复种水稻、籽粒玉米、青贮玉米、鲜食玉米等作物,实现粮饲结合,为宁夏引黄灌区耕作制度改革和种植业结构调整提供更大的空间。In order to select right height harvest period of Secale carele L. in Ningxia,the fresh weight and dry weight performance were compared and analyzed by variance analysis. Nutritional quality,and results of a comprehensive analysis of yield and nutritional quality indicators were investigated. The results showed that： the appropriate height harvest period of Secale carele L. in Ningxia is in the range of 90 - 150 cm,the corresponding time is May 4th to 16th,it was in Heading to Flowering period. In this range,the fresh weigh and dry weigh were higher,the content of crude protein was higher,the content of neutral detergent fiber was moderate and the comprehensive characters were better,in this range,it＇s suitable for feeding cattle,sheep and other ruminants. After harvest,rice,grain corn,silage corn and fresh corn can be multiple cropped,and then food can be integrated with feed,it will provide more space for reforming the farming system and adjusting the planting structure.
