春玉米与春小麦间作,属于大田作物高矮秆搭配,充分利用田间条件,提高作物的单产量,粮食效益能增加1.5倍,大大提高了土地利用指数。春玉米与春小麦间作高产栽培技术适宜在无霜期为120～150天,大于或等于10℃活动积温2600～3400℃的冀北、辽宁、内蒙古等地种植。
Spring intercropping of spring maize and spring wheat is a field crop with tall stalks, make full use of field conditions and improve crop yields, food efficiency can increase 1.5 times, greatly improving the land use index. The intercropping techniques of spring maize and spring wheat are suitable for cultivation in north Hebei, Liaoning and Inner Mongolia where the frost-free period is 120 ~ 150 days and the active accumulated temperature is 10 ~ 2600 ~ 3400 ℃.
