| Abstract: | The change law of soil nutrients and 4 kinds of trace elements condition of abundance or deficiency in Yunnan sugarcane area was analyzed. Scheme of sugarcane soil testing and fertilization recommendation technology were established. There had been proposed 32 formulas of sugarcane soil testing and fertilization recommendation technology which adapted different ecological soil types of sugarcane area. This formula had applied in 57,000 hectares sugarcane zone. Cane yield increased 8.10-10.95 t/ha, sucrose content increased by 0.21%-0.5% on average. At the same time, chemical fertilizer input saved 72-225 yuan （RMB）/ha. Sugarcane soil testing and fertilization recommendation technology saved cost, increased income and reached to industrialized application. |
