摘　　要：[目的]为了避免连年使用除草剂单一的甘蔗除草膜引起的杂草防效下降以及环境污染等问题,筛选几种甘蔗除草膜在翁源蔗区开展相关的田间试验。[方法]以粤引11号为试验材料,分析不同除草膜对杂草的防效和甘蔗产量的影响。[结果]不同的甘蔗除草膜对杂草的总防效均在80%以上,对牛筋草的防效最高,对马唐的防效次之,而对多年生禾本科杂草香附子的防效最差;各处理以甘蔗除草膜(含除草剂莠去津和乙草胺)的产量最高;生物降解除草膜满足甘蔗的生长需要,收获期产量达到88215 kg/hm2。[结论]生物降解除草膜是一种既环保又利于甘蔗高产的绿色产品。[ Objective ] Field experiment of different herbicidal much films was carried out in Wengyuan sugarcane area in order to avoid weed control decline and environmental pollution caused by used herbicides single plastic film long-term.[ Method ] Taking Yueyin 11 as test material, effect of different plastic films mulching on weeds control effects and yield of sugarcane was analyzed. [ Result] The total control effect of different herbicidal mulching films was above 80%,the control effect of the Goosegrass herb was highest,and the control effect of the Digitaria sanguinalis was higher than Cyperus rotundus. The yield of herbicidal plastic film （including herbicide atrazine and aeetoehlor） was the highest in each treatment, biodegradable herbicide mulching fihn meet the growth requirement of sugarcane, yield was 8 8215 kg per hectare in harvest period. [ Conclusion ]Biodegradable herbicide mulching fihn was green product which was beneficial to sugarcane production.
