摘　　要：为了探讨宿根蔗平茬对甘蔗出苗的影响,就甘蔗品种“GT42”进行了宿根蔗平茬的试验。研究结果表明:宿根蔗平茬后能提高甘蔗发株率、分蘖率,增加甘蔗有效茎,提高产量和含糖量,对甘蔗株高、茎径影响不明显;平茬+腐殖酸处理与平茬处理效果相当。Conducted a stumping experiment on sugarcane GT42 to investigate the effect of stumping technology on ratoon sugarcane germination.Results showed that cutting sugarcane stubble could increase the emergence percentage,tillering percentage,effective stalk,yield and sugar content of ratoon sugarcane,but did not obviously affect the plant height and stem diameter;the effect of stumping+humic acid treatment was equivalent to that of stumping treatment.
