马铃薯、玉米和白菜通过合理间作套种,可以充分利用高矮秆作物的立体生长空间,有效提高光能利用率,大大提高种植效益。平均亩效益超过3000元,比常规小麦-玉米连作模式的亩效益提高了2倍多。一、选地整地土地要尽量选择肥厚疏松的沙壤土质,以利于马铃薯块茎的膨大生长。整地时亩 Potato, corn and cabbage intercropping through reasonable interplanting, can make full use of high-stalk crop three-dimensional growth space, effectively improve the utilization of light energy, greatly enhance the planting efficiency. The average yield per mu is more than 3,000 yuan, which is more than double that of the conventional wheat-corn continuous cropping system. First, the selection of land preparation Land should try to choose loose sandy loam soil quality, in order to facilitate the expansion of potato tubers growth. When the preparation of acres
