摘　　要：不同控释氮肥田间试验结果表明,控释氮肥与普通氮肥相比不仅能提高春玉米子粒产量,而且能提高玉米子粒中粗脂肪含量。春玉米的适宜施N量为150kg/hm2。控释氮肥与普通氮肥混合施用可显著提高春玉米产量,最佳混配比例为50%控释尿素+50%普通尿素。Field experiment showed that controlled release N fertilizer could not only increase spring maize yield but also increase its crude fat content, and the appropriate fertilization rate was N 150 kg/ha for spring maize. Mixed application of controlled release N and common N could increase maize yield obviously, and the optimum mixed proportion was 50% controlled release urea ＋ 50% common urea.
