摘　　要：滇西南赤红壤、砖红壤蔗区农业地质背景诸因素中，甘蔗所需的营养元素磷、硅、硫缺乏而广，少钾、氮不足，铜、锰含量丰富，硼、钼一般不缺，锌含量中等偏低。增施磷、钾、硅、硫、锌均有不同的增产效果，磷>钾>硅>硫和锌。Among factors of agrogeological background of southwestern Yunatn telated to the lateritic red loam and laterite cane region. It is generally lack of P, Si and S,with less K, N, but Cu and Mn is rich. lt is seldom lack of B and Mo, Zn is from medium to low,different cane yield was increased by applying P. K, Si, S, Zn. P> K>Si> S and Zn were generally applied.
