摘　　要：设置5个处理,探究不同氮磷钾施用量对甘蔗生长及其产量的影响。结果表明,T3处理(尿素900kg/hm2、钙镁磷肥900kg/hm2、氯化钾393kg/hm2)的施肥量对提高产量及改善品质具有一定作用,其蔗茎产量达100099.95kg/hm2,蔗糖产量达14324.25kg/hm2,与其他处理差异显著;T1处理农艺性状、蔗茎产量及蔗糖产量最低;T2、T4、T5处理蔗茎产量及蔗糖产量高于T1处理,但比T3处理蔗茎产量及蔗糖产量低,因此T3处理施肥量为最佳施肥方法。To explore the effects of different N, P and K application rates on sugarcane growth and its yield, five treatments were set up in this experiment. The results showed that the T 3 treatment (urea 900 kg/hm 2, calcium magnesium phosphate fertilizer 900 kg/hm 2, potassium chloride 393 kg/hm 2) had a certain effect on increasing yield and improving quality. The yield reached 100 099.95 kg/hm 2 and the yield of sugar 14 324.25 kg/hm 2 was significantly different from other treatments;T 1 treatment had the lowest agronomic traits, yield and sugar yield in each treatment;yield and sugar production of T 2, T 4, T 5 treatment was higher than T 1 treatment, but it was lower than yield and sugar production of T 3 treatment. Therefore, T 3 treatment fertilization was the best fertilization method.
