玉米、大豆间作是改善玉米通风透光条件,充分发挥玉米边行优势,提高玉米产量的有效措施。但玉米、大豆间作涉及的问题较多,密度不合理,栽培管理粗放,就达不到增产的效果;行比配置不当,虽然玉米增产,大豆可能减产,不能实现粮、油双丰收。我们对1970年以来的有关调查资料,进行了分析整理,对玉米、大豆间作行比问题,提出以下看法。
Intercropping of corn and soybean is an effective measure to improve the ventilation and light conditions of corn, give full play to the advantages of corn and improve the yield of corn. However, there are many problems involved in the intercropping of maize and soybean, such as irrational density and extensive cultivation and management, which can not achieve the effect of increasing yield. However, due to the improper allocation of maize and soybean, the output of soybean may be reduced and the yield of grain and oil may not be doubled. We have analyzed and sorted out the relevant survey data since 1970 and put forward the following views on the issue of the ratio between corn and soybean.
