The invention discloses a high-yield planting method for silage corn in a plateau slope. The method comprises the steps of selecting a good variety, deeply ploughing the land, sufficiently applying base fertilizer, watering soil moisture water, reasonably and densely planting, pollinating, preventing and controlling diseases and insect pests, timely harvesting and the like. The method further comprises a step of pretreating the excellent variety before sowing after the excellent variety is selected and before rational close planting is carried out; wherein the pretreatment before sowing specifically comprises the steps that excellent silage corn seeds from the northern area are taken, the germination temperature is sequentially adjusted from-10 DEG C to 30 DEG C to-10 DEG C within 2-7 days, the temperature adjustment time of each time is 6-24 h, and the temperature adjustment span of each time is 5-20 DEG C. By the adoption of the method, when the silage corn seeds in the northern area are introduced into the
