玉米马铃薯高密度通透栽培技术研究初报

充分利用早熟马铃薯与晚熟玉米生育期一长一短的时间差和植株一高一矮的空间差,通过田间科学巧妙的栽培方式,形成了作物生育前期马铃薯玉米2∶1的间作格局;可实现玉米的高密度种植。在肥、水条件充足时,玉米的密度与清种比可增加300%。这样在单位面积土地上,可得到一季早熟马铃薯,又可得到一季玉米,实现了北方高寒地区一季双作,大大提高了土地利用率和光能利用率。

Study on Ventilation and Photop-permeability Cultivation of Maize and Potato at High Cropping Density

Taking advantage of the different growing period and plant height of potato and maize,the 2 t 1 pattern intercropping planting of the two crops was established. It realized a high density planting maize. The density could be increased up to 300 % as normal cropping when the water and nutrient condition were abundant, So we could harvest a crop of potato,in addition of a crop of maize,to accomplish a double cropping in cold region,which greatly enhanced the efficiency of light energy utilization and the land utilization.
