本文综合介绍了除草地膜的特点和除草机理,并对使用除草膜时如何提高除草效果作了详细的说明。蔗田使用除草地膜对由种子长出的各种杂草总防除效果达90%以上,有效期达三个月,与不盖膜比较,每亩可增产甘蔗1~1.5t。同时对使用除草膜与喷除草剂盖膜和不用地膜作了苗期的经济投入和劳力投入的比较,除草膜处理在经济效益上是最好的。近5年来南方主要蔗区推广甘蔗除草膜面积已超过38万亩。
This paper introduces the characteristics of weeding film and weeding mechanism, and gives a detailed description of how to improve the weeding effect when using it. Cane field herbicidal effect on the weeds by the seeds of more than 90% of the total control effect, the validity of up to three months, compared with the non-covered membrane, an increase of 1 to 1.5 tons of sugar per acre. At the same time on the use of herbicidal and herbicide-coated membrane and without the film made seedling economic investment and labor input comparison, weeding film processing is the best in economic efficiency. In the past five years, the main sugarcane planting area in southern China has exceeded 38 million mu.
