| Abstract: | The soil testing and fertilizer recommendation experiment was conducted by planting sugarcane ROC 25 on the sandshale with parent material of acidic lateritic red soil.The results showed that the soil testing and fertilizer recommendation had obvious promotion effect on increasing yield and sugar content of sugarcane.Compared with conventional fertilization and non-fertilization,the yield was increased by 7.5% and 75.2%,the sugar contents increased by 0.8% and 1.8%,and the sugar yield increased by 12.5% and 89.8% respectively.The production cost reduced by 454 yuan（RMB） per hectare.The net-increased benefit increased by 11.2% and 43.3% respectively.It has a remarkable yield and income increase. |
