The invention relates to the technical field of artificial grassland planting, in particular to a planting method of harvesting both arrhenatherum elatius and feed brassica napus in a high-altitude cold region. The main technology includes the steps that when 10 cm of early spring soil defrosts, arrhenatherum elatius is sowed and is harvested in a grain filling stage; then, root systems and tillers during first harvest are removed, no land needs to be levelled, feed brassica napus is directly resowed and is harvested before a final flowering stage. According to the technology, the high-altitude cold region has the climatic features of being low in temperature, windy, sandy, short in frost-free period, limited in accumulated temperature and the like during early spring, and the climatic features of the high-altitude cold region are comprehensively taken into account; arrhenatherum elatius and feed brassica napus are sowed in sequence in two rounds, effective accumulated temperature, annual sunshine duration an
