Abstract: This experiment was conducted to study the effects of combined application of organic fertilizer and chemical fertilizer on the production performance, nutritional quality and economic benefits of different triticale (×Triticosecale) varieties, and to provide theoretical basis for high yield cultivation techniques of triticale in dry farming areas of central Gansu. The experiment used a split-plot design, and the main plot factor was nitrogen application rate, which was set at four levels: 120 (A1), 240 (A2), 360 (A3), and 480 kg·hm-2 N (A4). For these nitrogen application treatments, nitrogen was applied as a combination of organic fertilizer and urea, with 2/3 of the nitrogen from organic fertilizer used as base fertilizer and 1/3 from urea as topdressing. Two control treatments were also included: no fertilization (CK1) and single application of chemical fertilizer (CK2). The subplot was two triticale varieties (C1: ‘Gannong No.2’; C2: ‘Gannong No.4’). The results showed that among the fertilization treatments, when the combined application rate of organic fertilizer and chemical fertilizer was 360 kg·hm-2 N, the average hay yield (8.36 t·hm-2), crude protein content (10.73%), and comprehensive evaluation value (0.95%) of the two triticale varieties were relatively higher. From the perspective of triticale varieties, the comprehensive evaluation value of ‘Gannong 2’ triticale (0.60) was higher than that of ‘Gannong 4’ triticale (0.40). Their interaction showed that when the combined application of organic fertilizer and chemical fertilizer was 360 kg·hm-2 N, the comprehensive evaluation value of Gannong No.2 was the highest (0.84), which was higher than that of the two triticale varieties under single application of chemical fertilizer (0.52, 0.72). In conclusion, under dry climate conditions, to balance high-quality and high-yield forage as well as economic benefits, the recommended nitrogen application strategy is as follows: for ‘Gannong 2’ triticale, a combined application of organic fertilizer and chemical fertilizer at a rate of 240 kg·hm-2 N is suitable; for 'Gannong 4' triticale, a single application of chemical fertilizer at 360 kg·hm-2 N is appropriate.

摘要: 本试验旨在研究有机肥与化肥配施对不同小黑麦(×Triticosecale)品种生产性能、营养品质和经济效益的影响,为甘肃中部旱区小黑麦高产栽培技术提供指导。试验采用裂区设计,主区为施氮量,设120(A1),240(A2),360(A3),480 kg·hm-2 N(A4)4个水平,采用2/3有机肥作为基肥、1/3尿素作为追肥的方式配施,不施肥(CK1)和单施化肥处理(CK2)作为对照;副区为2个小黑麦品种(C1:‘甘农2号’;C2:‘甘农4号’)。结果表明,从施肥处理看,配施量为360 kg·hm-2 N时,2个小黑麦品种的平均干草产量(8.36 t·hm-2)、粗蛋白含量(10.73%)和综合评价值(0.95)较高;从小黑麦品种看,‘甘农2号’小黑麦的综合评价值(0.60)高于‘甘农4号’小黑麦(0.40);交互作用下,配施量为360 kg·hm-2 N时,‘甘农2号’小黑麦的综合评价值最高(0.84),高于单施化肥下2个小黑麦的综合评价值(0.52,0.72)。综上,干旱条件下,兼顾饲草优质高产与经济效益,‘甘农2号’小黑麦宜选择240 kg·hm-2 N配施量,‘甘农4号’小黑麦宜选择单施化肥360 kg·hm-2 N。
