The method for planting herbages on granite red earth slopes comprises selection of species of herbages comprising selecting Gramineae herbages; soil preparation comprising digging small holes or seeding furrows in granite red earth slopes; treatment before seeding herbage seeds, dressing the seeds using a mixed solution composed of a titanium fertilizer and phosphate-solubilizing bacteria and yellow mud before seeding the herbage seeds; seeding comprising seeding ryegrass from September to October and seeding paspalum notatum flugge in February in next year in abrupt slopes, and seeding paspalum notatum flugge in February in the first year in gentle slops; management after seeding comprising covering seeds using nutrient soil after seeding, covering non-woven fabrics, and irrigating enough water. By adopting the method for planting herbages on the granite red earth slopes, sod can quickly recover on the naked granite red earth slopes, water and soil losses can distinctly reduced, physical and chemical properties of the soil can be improved, water, a fertilizer, gas and heat become coordination, growth of the herbage are benefited, soil resources which cannot be used in the past can be utilized at high efficiency.
