在龙陵县甘蔗主产区,以有机肥、磷钾肥作为底肥,氮肥作追肥：设不同时期、不同施氮量6个处理,探讨优化甘蔗追肥不同分配比例、施肥时期和施肥方法。试验结果表明：处理B(氮肥总量1/4分别作苗肥和壮尾肥,2/4作拔节肥)的甘蔗产量为109.02 t/hm2,比常规施肥(氮肥全部作拔节肥)的90.94 t/hm2增18.08 t/hm2,增幅19.88%；处理B的产糖量为13.55 t/hm2,比处理A的10.91 t/hm2增2.64 t/hm2,增幅24.2%。处理B增产增糖效果十分明显,值得推广应用。

The sugarcane fertilization experiment was conducted to test effect of applying organic, phosphate and potassium fertilizer as base fertilizer, the nitrogen fertilizer of 6 treatments as after manuring under different stages and application amount in comparison with the conventional fertilization in the Longling area. The results showed that: the treatment B (1/4 nitrogen fertilizer applied at seed bed and later growing stage, 2/4 nitrogen fertilizer applied at elongation stage) was superior to the others, the cane yield was up 109.02 t/ha, increased by 18.08 t/ha (19.88%);sugar yield was 13.55 t/ha, increased by 2.64 t/ha (24.2%), in comparison with the treatment A, conventional fertilization (all nitrogen fertilizer applied at elongation stage). Therefore, the treatment B was very effective to increase cane yield and sugar yield.
