The invention provides a rice wheat full mechanical high-yield high-efficiency planting method. The method adopts a rice wheat two-cropping planting mode and full mechanical production. The planting method includes: performing preparation before wheat sowing, selecting and air-drying seeds, mixing the seeds with a farm chemical agent, performing fine-sowing, stabilizing moisture in soil, allowingseedlings to grow orderly, and strengthening the seedlings; promoting rooting and tillering, and cultivating strong seedlings; performing adjustment and control at suitable time, promoting growth of weak seedlings, controlling vigorous growth, allowing strong seedlings to safely overwinter, lifting the seedlings, stabilizing growth, hardening the seedlings, and strengthening tillers; consolidatingvalid tillers, and ensuring full and big ears; applying an elongation booting fertilizer; rearing roots, protecting leaves, preventing green retaining and premature aging, increasing grains and the weight, performing watering to resist drought, performing drainage to reduce the moisture and prevent premature aging, and performing rice sowing preparation and rice sowing at the same time; performing high-quality mechanical rice transplanting, performing quick reviving, finely preparing a large field, and applying a sufficient base fertilizer; ensuring full ears during a valid tillering stage ofthe rice; controlling invalid tillering during an invalid tillering stage of the rice; strengthening roots and stems so as to promote big ears; rearing roots, protecting leaves, increasing grains andthe weight, and improving the quality. The planting method is supported by a matching intercropping technology adapting to mechanical operations, is scientific in planting, and can achieve increase in grain yield and income.
