摘　　要：随着近几年我国南方冬季平均气温的持续走低,能否在冬季采用积极有效的蕉园护理措施关系到广西香蕉产业未来的生死存亡。本文对在广西金穗公司发现的两块越冬后长势差异明显的香蕉园进行了对比分析。其中天地膜结合使用的蕉园植株长势健壮,叶色翠绿,相比仅使用地膜的蕉园植株片叶,且整齐度较好;仅使用地膜的蕉园虽然能大部分植株存活,但植株长势明显较弱,叶片受冻损伤严重。另外使用天地膜地块的杂草相对地膜地块少,且杂草在假茎周围没有富集。在操作成本上,天膜除需要架设竹条消耗一定人力物力外,膜用量与地膜差别不大。综合分析两种蕉园冬季护理方式,天膜可以更有效地降低霜冻对香蕉产业的风险,提高香蕉植株群体越冬能力,抑制杂草滋生,防止冻雨在垄底淤积,在广西有非常大的推广潜力和应用价值。In recent years, the average winter temperature of south China is keeping on falling down, and the active and effective protection of bananas from cold damage to the future of Guangxi banana industry. This article has a comparative with two pieces of parcel with different growth vigour face the low temperature in Guangxi Jinsui Agricultural Investment Group Co., Ltd. In the treatment of high bestrow, the plants are lusty and the leaves are verdant. Compared with the only low bestrow treatment, there are 2--4 more pieces of leaves and have a better orderliness. The low bestrow can keep the plants alive, but the leaves which didn＇t protect well were damaged badly, the bananas seem obviously weak. Besides, there are fewer weeds under plastic tunnel cultivation than that of plastic membrane mulching. It should have certain human and material consumption in the operation costing under plastic tunnel cultivation, but the plastic mulch used in the plastic tunnel cultivation is as many as in the plastic membrane mulching. The analysis by synthesis showed that the plastic tunnel mulching could reduce, the risk of banana industry. We can improve the overwintering ability of banana plant populations, suppress weeds, and prevent the cold rainwater accumulating at the bottom of ridges by this way. It has broad application value and potentiality.
