摘　　要：土壤盐碱化降低了小黑麦生物产量,研究轻度盐碱化土地上不同因素对饲用小黑麦产量的影响,为盐碱地上饲用小黑麦高产优质栽培提供理论依据;利用4因素3水平正交设计方法,研究了不同种植密度(B)、底肥量(C)、追肥量(D)对3个优良饲用小黑麦品种(品系)(A):‘哈师209’、‘哈师0442’、‘哈师0447’鲜草产量的影响,并对不同组合鲜草产量的结果进行分析;密度对小黑麦鲜草产量影响显著,且不同密度之间差异极显著,其他3个因素对产量影响不显著,各因子对小黑麦鲜草产量的影响程度依次为:种植密度>品种>底肥量>追肥量;在供试条件下,适宜的品种为‘哈师209’,播种量为300kg/hm2,施用复合底肥300kg/hm2,刈割后追尿素肥75kg/hm2。Soil salinity reduces the triticale biomass,the research of slightly salinization of land different factors on the yield of forage triticale,of saline on the cultivation of high yield and quality forage triticale provide a theoretical basis.Using 4 factors and 3-levels orthogonal design method,research the effects of different planting densities（B）,the amount of base fertilizer（C）,the amount of fertilizer（D） to affect 3 excellent forage triticale（Triticum secale） varieties（strain）（A）：＇ Hashi209 ＇,＇ Hashi0442 ＇,＇ Hashi0447 ＇ yield of fresh grass,and analysis of the results of different combinations of fresh yield.Fresh yield of triticale density significantly affected,and between different densities significantly different,the other three factors had no significant impact on yield,various factors on the fresh yield of triticale were the degree of influence：planting densityvarietythe amount of base fertilizer the amount of fertilizer.In the test condition,suitable varieties for the ＇ Hashi209 ＇,seeding rate of 300 kg/hm 2,using composite base fertilizer 300 kg/hm 2,after cutting add tol urea fertilizer 75 kg/hm 2.
