分析目前广西桂西南香蕉主产区不同宿根栽培年限蕉园在香蕉生长、蕉园管理难度、蕉园成本收益上的差异，提出限制延长蕉园宿根栽培年限的主要因素是种植密度的显著下降：宿根栽培2年的蕉园经济收益最高，随着宿根栽培年限的延长，蕉园经济收益逐年下降。就此提出合理延长蕉园宿根栽培年限的管理措施。

The difference among growth, routine management, cost and benefits of major banana plantations with differ-ent planting years in Southwest of Guangxi province is analyzed. The decreasing planting density is sup-posed to be the most important factor affecting planting length. The highest economic benefit could be obtained in planta-tions being planted for two years in succession, and gradually decline with the year goes. The recommenda-tions on how to lengthen the plantations life in a reasonable way are presented.
