摘　　要：测定了滇东南、滇西、滇南等蔗区土壤养分含量。结果表明:不同蔗区间土壤基础肥力存在明显差异,同一蔗区内的变化差异更大。结合影响云南蔗区土壤肥力差异变化的施肥、耕作制度、土壤类型等因素,分析了测土配方施肥对保持蔗区土壤肥力平衡,提高甘蔗单产和质量的增产潜力。By measuring the soil nutrient content in southeastern Yunnan, western Yunnan, southern Yunnan and other cane regions, the result indicated that there were significantly different fertilities among the cane regions, and there were even much more differences in the same cane region. The effects of filling the prescription on keeping the soil fertility balance and the potential of improving cane yield and quantity were discussed by analyzing the factors of fertilization, cultivation rule and soil types.
