The present invention relates to a method for fertilizing corn in a semi-humid region for one time, and belongs to the field of agricultural fertilization. The method adopts a corn seeding and fertilizing combined machine to sow and fertilize for one time in a semi-humid region. The method realizes nutrient supply throughout the growth of corn without performing top dressing in a later stage. The method improves fertilizer utilization, saves labor cost and improves production and income. The present invention effectively improves ventilation and light transmission conditions in the corn field, eliminates the effect of a stubble of a preceding crop on the emergence of corn, improves uniformity, and reduces nutrient loss.

A method for treating bauxite residue contained in a storage facility comprising adding a mixture containing (a) a source of organic carbon, (b) a source of phosphorous or a source of phosphate, (c) a source of calcium, and a source of sulphur or sulphate to the bauxite residue, to thereby promote growth of microbes well adapted to highly saline and alkaline habitat, or to promote growth of marine microbes, or to promote growth of tolerant and marine origin haloalkaliphilic bacteria, or to promote growth of haloalkaliphilic organotrophic bacteria, preferably of marine origin. The method may comprise adding plant material or mulch and superphosphate fertilisers to the bauxite residue.

A one-off fertilization method suitable for winter wheat in areas with less rainfall in spring includes the following steps: (1) carrying out, on a flat wheat block which is suitable for mechanized operations and after the harvest of preceding crops, a deep ploughing or a subsoiling in combination with a rotary tillage and a one-off fertilization for land preparation, without involving any top dressing in a later stage; and (2) carrying out a seeding operation by a wheat seeder, wherein for nitrogen fertilizer, according to the nitrogen release period of a controlled-release nitrogen fertilizer, one of the following application modes is determined: applying a polyurethane-coated controlled-release nitrogen fertilizer alone or a water-based resin-coated controlled-release nitrogen fertilizer special for winter wheat alone; or applying a water-based resin-coated controlled-release nitrogen fertilizer special for winter wheat in combination with 20% to 30% of a polyurethane-coated controlled-release nitrogen fertilizer.
