中文摘要:

      [目的] 探索研究适于平凉市东部旱作农业区乃至陇东地区发展牛产业的饲草料新型高效生产模式。[方法]在平凉市选有代表性的东部旱塬地,开展了农作物“三年五熟”种植模式和连年春播模式试验研究,评估分析了不同种植模式的生产效益。[结果] 在同一生产周期(三年)内,“三年五熟”种植模式全株玉米秸秆单位面积产量显著低于连年春播模式(P<0.05),但可显著降低单位面积玉米秸秆生产成本,其产出投入比显著高于连年春播模式(P<0.05)。[结论] “三年五熟”种植模式可有效降低肉牛养殖中饲草料生产成本,适宜在全市乃至陇东地区规模化养牛场中推广应用。

英文摘要:

      【Objective】 The objective of this study was to explore and research a new and efficient forage production mode, which suitable for the development of cattle industry in the dry farming area of eastern Pingliang and even in Longdong area.【Method】 A representative eastern drought-flooded area was selected in Pingliang City where an experiment of "three years for five crops" planting pattern and continuous spring sowing pattern was carried out, and the production benefit of different planting patterns were evaluated and analyzed.【Result】In the same production cycle (three years), the yield per unit area of the whole corn stalk in the "three years for five crops planting pattern was significantly lower than that in the continuous spring sowing pattern (P<0.05), but the production cost was significantly reduced, the output and input ratio was significantly higher than that of the continuous spring sowing pattern (P< 0.05).【Conclusion】The planting pattern of "three years for five crops" could effectively reduce the production cost of forage in beef cattle breeding, which is suitable for popularization and application in large-scale cattle farms in Pingliang city and even around Longdong area.
