| Abstract: |
| This study researched the fertilization technology of sugarcane in order to further explore the cultivation
mode of sugarcane with high yield and rich sugar，increase fertilizer use efficiency，reduce labor costs and maximize the
benefits of sugarcane planting. Sugarcane variety GT97-69 was used as material，Jin Zhengda，Jiutian and Fulilong ware
used as fertilizer. The frequency of fertilization and the kind of fertilizer were the two main factors in this experiment，
6 different treatment combinations（A1B1，A2B1，A3B1，A1B2，A2B2，A3B2）ware set in the whole stages of GT97-69，
A standed for the kind of fertilizer and B standed for the frequency of fertilization. The results showed that the sugarcane
tillering rate of fertilization doubled 55.2% lower than that of single-dose application. The sugarcane stem yield of
secondary fertilizer increased by 660 kg / 667 m2 than single-dose application，and the difference reached significant
level. In terms of number of fertilizer variety and fertilization interaction，by application of compound fertilizer，
sugarcane stem yield，and sugar content ranked high，and the treatment had good comprehensive properties. In terms of
economic efficiency，secondary fertilizer was higher than single-dose fertilization. |
