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 alkalinization reduced the yield of triticale and studied the effects of different factors on the yield of triticale on mild saline soil so as to provide theoretical basis for the high yield and quality cultivation of feed triticale in saline soil. 3 horizontal orthogonal design method was used to study the effects of different planting density (B), base fertilizer (C), dressing dose (D) on three excellent triticale varieties (lines) ’Ha-0442’, ’Ha-0447’ fresh grass production and the results of different combinations of fresh grass yield were analyzed; density had a significant impact on the yield of triticale, and the difference between the different density was significant, the other The effect of three factors on the yield of triticale was as follows: planting density> cultivar> base fertilizer> topdressing amount; under the conditions of the test, the suitable cultivar was ’Ha-209’ , Seeding rate of 300kg / hm2, the application of 300kg / hm2 compound base fertilizer, mowing urea fertilizer 75kg / hm2.
