Abstract:In this study, the corn variety of Leyu No.1 was used as the experimental material, 6 treatments were designed which include T1, no nitrogen; T2, 100% base urea; T3, 100% urea with 1∶1 ratio of base feitilier to topressing; T4, 37.5 % urea + 62.5% controlled release urea; T5, 70% urea+30% organic-inorganic compound fertilizer; T6, 37.5% urea+30% organic-inorganic compound fertilizer+32.5% controlled release urea, and then the effects of above treatments on soil nutrient utilization, the uptake of nitrogen, phosphorus and potassium by maize, maize yield and its components, and nitrogen use efficiency of maize were investigated in order to find the optimal nitrogen application method for spring maize in Heilongjiang. The results showed that for T6 treatment, the contents of soil ammonium nitrogen and nitrate nitrogen were the lowest except T1 at the maturity stage, nitrogen accumulation and dry matter weight of corn leaves and stalks were the highest in the other three periods except the jointing stage, corn yield was 1 1428 kg/hm2, increased by 24.82% compared with T1, and the agronomic efficiency and the partial productivity of nitrogen fertilizer both were the highest. In conclusion, T6 was the optimal nitrogen application method for spring maize growth in Heilongjiang.
