摘　　要：研究分析了云南蔗区土壤养分变化规律和4种微量元素的丰缺状况；研究建立了甘蔗测土配方施肥技术方案，研制了32个适宜不同土壤生态类型蔗区的甘蔗测土施肥配方，推广应用面积5．7万hm^2，平均增产甘蔗8．10～10．95t／hm^2，提高蔗糖分0．21％-0．5％。同时，节省化肥投入72-225／hm^2，实现了甘蔗测土配方施肥的节本增效产业化推广应用。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.
