Sugarcane mechanized harvesting requires wide row spacing. The paper studied the growth and yield of Yuetang 94-128 planted with 1.0, 1.2, and 1.4 m row spacing in field in Zhanjiang area. Results showed that Yuetang 94-128 had good adaptability to 1.2 and 1.4 row spacing in the area. The cane yields planted with 1.2 and 1.4 row spacing were higher than that planted with 1.0 row spacing. The cane yield planted with 1.2 m row spacing was higher than that planted with 1.4 m row spacing. The results were helpful for the extension of wide row spacing cultivation in the area.%甘蔗机械化收获要求合适的种植行距。本文以湛江地区普遍种植的粤糖94-128品种为例，研究在1.0、1.2和1.4 m 种植行距下新植蔗和第1～2年宿根蔗在大田的表现。结果表明，该品种在湛江遂溪地区适合1.2 m 和1.4 m 行距的种植模式。采用1.2 m 和1.4 m 行距的甘蔗产量高于采用1.0 m 行距的产量，1.2 m 行距下产量略高于1.4 m 行距下的产量。本文的研究结果对推动甘蔗宽行距在湛江地区种植具有积极作用。
