Analysis of Agronomic Characters and Agricultural Economic Benefits of Directly Replanting of the 3nd Year Ratoon Sugarcane

  • 摘要:   目的  探究种茎直接补种对宿根蔗3年延长年限农艺性状和产量的影响,为进一步推广甘蔗种茎直接补种延长宿根蔗生产年限新技术提供依据。  方法  选取广西蔗区3个主栽品种桂柳2号(GL2)、桂糖44号(GT44)和粤糖00236(YT236)的第2年宿根蔗作为被补种群体,利用桂辐98-296(GF296)种茎对其栽种地块的缺株断垄蔗畦进行直接补种处理,以未补种群体为各自对照(CK),在宿根蔗第3年、第4年、第5年的收获期,分别测定补种和未补种处理甘蔗的农艺性状和蔗糖分,并计算经济效益。  结果  GL2、GT44和YT236经补种后有效茎数目目均显著高于CK,CK产量随宿根年限延长而减少,经补种后的群体产量随宿根年限延长而增加,在其他农艺性状的指标上无显著差异。未经补种的GL2、GT44和YT236群体的有效茎数目与宿根年限的呈极显著负相关,分别为−0.907、−0.931、−0.756;产量同样与宿根年限的呈极显著负相关,分别为−0.915、−0.905、−0.930;试验结果表明3个品种经补种后,宿根年限不与产量和有效茎数目呈负相关关系,表明了补种后甘蔗宿根年限能够延长;同时经补种后GL2、GT44和YT236群体的经济效益也有所增加,它们的3年宿根时期总计增加净收入分别为48120.80、46765.80、42398.60元·hm−2  结论  GF296种茎直接补种能有效延长3年宿根年限,从经济效益对比而言是划算的,适宜大面积推广。研究结果为构建高产和稳产群体、发挥甘蔗宿根潜力、实现稳产高产栽培提供理论依据。
