摘　　要：研究旱地甘蔗新植与宿根地膜全覆盖技术和不覆盖种植条件下对甘蔗产质量及效益的影响。试验结果表明,甘蔗地膜全覆盖处理的株高、单茎重、有效茎、产量、糖分和所产生的经济效益均显著高于不覆盖地膜的处理。新植甘蔗地膜全覆盖的平均产量133.9t/hm2,比不盖膜的高59.6%;效益为35407元/hm2,比不盖膜增加20892元/hm2,增效144%;宿根甘蔗地膜全覆盖的平均产量133.7t/hm2,比不盖膜的增高32.5%;效益为43951元/hm2,比不盖膜增加11986元/hm2,增效37.5%。此技术是旱地甘蔗保水保肥、增产增效、延长宿根年限的一项技术措施,值得推广。The experiment of both new planting and perennial root sugarcane was conducted to investigate the influence of mulching film until harvest on cane yield, sugar content and benefits. The results showed that the sugarcane planting with mulching film until harvest was superior to non mulching film at plant height, stem weight, effective stem, yield, sugar content and economic benefits. In new planting crop, under mulching film until harvest, mean sugarcane yield increased by 59.6%; benefits increase by 20892 yuan （RMB）/ha （144%）, in comparison with that of non mulching film. In ratoon crop, under mulching film until harvest, mean sugarcane yield increased by 32,5%; benefits increased by 11986 yuan （RMB）/ha （37.5%）, in comparison with that of non mulching film. This technology could help to preserve moisture and fertility of soil and improve yield and benefit of sugarcane, which is worth popularizing.
