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 effects of new planting and peat mulch film mulching on dryland sugarcane and the effects on the yield, quality and profit of sugarcane under the condition of non-covering planting were studied. The results showed that the plant height, single stem weight, effective stem, yield, sugar content and the economic benefits were all significantly higher than those without covering film. The average yield of newly planted sugarcane mulching film was 133.9t / hm2, which was 59.6% higher than that of the non-mulching film; the benefit was 35407 yuan / hm2, which increased by 20892 yuan / hm2 and 144% The average yield was 133.7t / hm2, which was 32.5% higher than that of the non-membrane; the benefit was 43951 yuan / hm2, which increased by 11986 yuan / hm2 and 37.5% higher than the non-membrane. This technique is a technical measure for dryland sugarcane to keep water and fertilizer, increase production and increase efficiency, and extend the perennial life, which is worth promoting.
