冬小麦茬复种饲用玉米效果研究

Study on the Effect of Multi-cropping Silage Maize of Wheat Stubble in Winter

为探索饲草料新型高效生产模式,在平凉市选有代表性的东部旱塬地,开展了冬小麦茬复种饲用玉米与普通春播玉米试验研究,分析了各自生产潜力及效果。结果表明,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。由此可见,小麦茬复种玉米可降低全株玉米秸秆生产成本,提高养殖场经济效益,在我市具有一定的推广价值。

In order to explore a new and efficient production pattern of silage production model, a representative eastern drought-flooded area was selected in Pingliang City, and an experiment was conducted to study the effects of winter wheat cornpositing forage maize and common spring sowing maize, and their respective production potentials and effects were analyzed. The results showed that under the multiple cropping pattern, the yield of whole plant corn straw 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. It can be seen that wheat, corn, and multiple cropping corn can reduce the production costs of whole plant corn stalks and increase the economic benefits of farms, which has a certain promotion value in our city.
