摘要
[目的]开展冬油菜茬复种饲用玉米生产潜力研究,为探索饲草料新型高效生产模式奠定理论基础。[方法]在平凉市选有代表性的东部旱塬地,开展冬油菜茬复种饲用玉米与普通春播玉米试验研究,分析各自生产潜力及效果。[结果]复种方式下全株玉米秸秆产量显著低于春播方式(P<0.05),生产成本明显低于春播方式。[结论]冬油菜茬复种玉米可降低全株玉米秸秆生产成本,提高养殖经济效益,在平凉市规模化养殖场有一定的推广价值。
[Objective] The study on the production potential of winter multi-cropping silage maize of rape stubble laid a theoretical foundation for exploring new efficient forage production mode. [Method] A representative eastern drought-flooded area was selected in Pingliang city, and an experiment was conducted to study the effects of winter rape stubble compositing forage maize and common spring sowing maize, and their respective production potentials and effects were analyzed. [Result] Under the multiple cropping pattern, the yield of whole plant corn stalks was significantly lower than that of spring sowing method(P< 0.05), and the production cost was obviously lower than that of spring sowing method. [Conclusion] The multi-cropping pattern of rape and corn can reduce the production cost of whole plant corn stalks and increase the economic benefits of farms, which has a certain promotion value in Pingliang.
