摘　　要：甘蔗高产高糖受品种、环境和栽培等综合因素作用。本试验旨在探索甘蔗伸长期氮肥不同施肥时间对产量及品质的影响。试验表明,甘蔗伸长期合理的施肥方式有利于提高产量和品质,甘蔗伸长期氮肥以7月1日施尿素15kg/667m2,7月21日施尿素15kg/667m2的施肥方式最佳。The yield and sugar content of sugarcane are impacted by variety, environment and cultivation etc.. This experiment is aiming at the impacts study of different nitrogen fertilization dates on yield and quality in sugarcane elongation period. The experiment results show that rational fertilization in elongation period is benefiting the increase of yield and quality. The best dates and application amounts are 1st July with carbamide 15kg/667m2, 21th, July with carbamide 15kg/667m2.
