Topdressing plays a very important role in the fertilization of corn. According to the demand for nutrients in corn, the fertilizer can be applied in a timely and appropriate amount. The role of top dressing is to achieve the goal of high yield of "stalking, attacking, and attacking".
Summer corn with a yield of 400 kg per mu only needs to be applied once with nitrogen fertilizer, and 25-35 kg of urea is applied deep in the 7-8 leaf stage of corn; for summer maize with a yield of 500-600 kg per mu, under the premise of applying fertilizer, the corn is large. In the trumpet period, deep application of urea is 35-40 kg; for summer maize with a yield of 600-700 kg per mu, top dressing is carried out twice under the premise of applying fertilizer: 20 kg of urea is applied in the 7-8 leaf stage of corn, in corn In the large bell mouth period, 25 kg of urea is applied in depth; for summer corn with 750 kg per mu, topdressing is carried out three times under the premise of applying fertilizer: 20 kg of urea is applied deep in the 7-8 leaf stage of corn, in the big trumpet period of corn Deep application of urea 25 to 30 kg, deep application of "Yugong" brand compound fertilizer (18-17-10) 15 to 20 kg in the period of corn tasseling.
