摘　　要：在盐碱化土壤上利用4因素3水平正交设计方法,测试不同种植密度(B)、不同底肥量(C)和不同追肥量(D)对3个饲用燕麦(AvenaSativaL.)品种(A)(‘白燕2号’、‘白燕6号’和‘白燕7号’)鲜草产量的不同影响效果,并对鲜草产量进行差异显著性鉴定。结果表明,密度对燕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,各因子对燕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‘白燕6号’,播种量为150kg/hm2,施用复合底肥375kg/hm2,刈割后追尿素肥75kg/hm2,采取这种种植方式可以达到燕麦鲜草最高产量。On the saline alkali soil,effect of different planting densities（B）,basal volume（C）,dressing rate（D） on yield of three kinds of feed oat（A）＇ Baiyan 2 ＇,＇ Baiyan 6 ＇,＇ Baiyan7 ＇-were studied by the method of orthogonal design of four factors and three levels,and yield of different combinations of fresh grass were analyzed.The results showed that,there were extremely significant differences in effect of different planting densities on yield of fresh grass,and effect of the other three factors were not significantly different.The influence degree of each factor on yield of fresh feed oat followed by planting densityvarietybasal amount of dressing rate.In the case of experiment,the best planting compound mode for the maximum yield was sowing ＇ Baiyan 6 ＇ 150 kg/hm^2,applying a compound fertilizer 375 kg/hm^2 and dressing 75 kg/hm^2 after cutting on the saline alkali soil.
