description The invention discloses a fertilization scheme screening method based on southern vegetable planting soil ammonia emission reduction, which comprises the following steps: S1, selecting a test sample plot, and treating the test sample plot; s2-1, equally dividing the test sample plot into a sample plot A and a sample plot B, and applying different amounts of urea to different areas of the sample plot A; s2-2, winter rape is planted in different areas of the sample plot A, and calcium phosphate and potassium chloride are subjected to topdressing; s3-1, applying a compound fertilizer formed by compounding urea, calcium phosphate and potassium chloride to different areas of the sample plot B, and planting winter rape; s3-2, carrying out an orthogonal experiment; s4-1, determining the ammonia emission in the growth period of the winter rape; s4-2, measuring the yield of the winter rape in the harvesting period; s4-3, performing variance analysis on the measurement result, and screening out a fertilization scheme w
