Summer corn with a yield of 400 kg per mu only needs one nitrogen topdressing, with 25-35 kg of urea deeply applied at the 7-8 leaf stage; for summer corn with a yield of 500-600 kg per mu, on the premise of applying seed fertilizer, 35-40 kg of urea should be deeply applied at the large trumpet stage; for summer corn with a yield of 600-700 kg per mu, on the premise of applying seed fertilizer, topdressing should be split into two applications: 20 kg of urea deeply applied at the 7-8 leaf stage, and 25 kg of urea deeply applied at the large trumpet stage; for summer corn with a yield of 750 kg per mu, on the premise of applying seed fertilizer, topdressing should be split into three applications: 20 kg of urea deeply applied at the 7-8 leaf stage, 25-30 kg of urea deeply applied at the large trumpet stage, and 15-20 kg of "Yugong" brand compound fertilizer (18-17-10) deeply applied at the tasseling stage.
