High-yield and cost-saving simple cultivation method for large-group small-entity summer sowing foxtail millet

The invention provides a high-yield and cost-saving simple cultivation method for large-group small-entity summer sowing foxtail millet. The high-yield and cost-saving simple cultivation method aims at achieving the mechanical wide-ridge plantation, simplifying procedures and reducing cost. The method includes the steps of selecting a ten-line wheat seeding machine with the sowing width of 200 cm; sequentially blocking seed discharge holes of the ten-line wheat seeding machine in an alternate mode from left to right, wherein the average line spacing is 40 cm; grasping the effective rainfall opportunity after the wheat harvest to complete the rotary tillage procedure, the sowing procedure and the pressing procedure at a time through the wheat sowing machine before the last ten days of June for the regions which have the accumulated temperature larger than or equal to 10 DEG C and have the temperature of about 1800 DEG C to 2000 DEG C during the period between the time when the wheat harvest is completed and the first ten days of October; spraying weed killers after sowing and before emergence or after emergency; adopting the thinning-free and final singling method when 3 to 5 main leaves appear on each millet seedling; conducting topdressing with 10 kilograms of urea in each mu at the elongation state through an intertillage soil moisture preservation and topdressing machine; conducting harvesting through a wheat harvester; reducing the speed of a draught fan system of the wheat harvester till grains can not be blown away.
