冬油菜茬复种饲用玉米效果研究

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。

Study on the Effect of Multi-cropping SilageMaize of Rape Stubble in Winter

Objective] To provide the theoretical foundation for exploring a new and efficient production pattern of silage production model, the productive potential of multi-cropping silage maize which after winter rape stubble was studied. 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] Undering 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] It can be seen that, 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.
