The spring sowing corn is mainly based on the bottom fertilizer. In addition to the farmyard manure, the base fertilizer is applied with 10 kg of urea, 10 kg of diammonium (or 25-40 kg of superphosphate), and 15 to 30 kg of "Saizhong 28" fertilizer. Mix and spread, pour the ground and sow. Fertilizer: 4~5kg seeds need 1kg "赛众28" seed dressing agent, first use the cold noodle soup or water to sprinkle the seeds, add the seed dressing and mix well, fully adhere, dry and sow. Topdressing is mainly based on nitrogen: spring corn needs to be chased twice in nitrogen, and 40-50 kg of ammonium bicarbonate or 15 kg of urea is chased per acre in the small trumpet period and the large trumpet period.
According to a large number of experimental demonstrations and field planting results, the application of "Saizhong 28" fertilizer can effectively prevent and cure corn zinc deficiency, corn bacterial wilt and ear rot, prevent the baldness of the ear, and improve the yield and yield.
