摘　　要：[目的]研究了不同种植期(冬植,春植)对不同品种甘蔗生产的影响。[方法]采用桂糖21、桂糖26和桂糖27作为参试甘蔗品种,调查了不同种植期不同甘蔗品种农艺性状、产量、产糖量和蔗糖分等指标,并进行差异显著性分析。[结果]冬植蔗在甘蔗农艺性状方面表现优于春植蔗,冬植蔗与春植蔗产量和含糖量间差异性达显著(P<0.05)或极显著水平(P<0.01);冬植蔗蔗糖分均高于春植蔗。除桂糖26外,桂糖21和桂糖27冬植蔗产量和产糖量均明显高于春植蔗,差异性显著。[结论]甘蔗冬植获得较高的产量和经济效益,可因地制宜的进行推广。[Objective] Experiments were conducted to study the effects of different sowing date（winter-planting and spring-planting） on production of different varieties of sugarcane.[Method] Agronomic characters,yield,sugar yield and sucrose content of the sugarcane variety GT21,GT26 and GT27 were investigated,and the data were analyzed by significance test.[Results]The results indicated that the agronomic characters and sucrose content of winter-planting cane were better than that of spring-planting cane,with significant（P0.05） or extremely significant differences（P0.01） between the cane yield,sugar yield of winter-planting cane and spring-planting cane.The cane yield and sugar yield of GT21 and GT27 of winter-planting cane were higher than that of spring-planting cane,with significantly differences except GT26.[Conclusion] Winter-planting sugarcane could obtain higher yield and economic benefits,and it could be recommended for extension with local conditions in sugarcane production.
