氟乐灵除草剂(指48％的乳剂,下同)从1980年起开始在江苏农垦系统棉田大面积推广应用,去年使用面积已达30.29万亩,占棉田面积的94.62％。棉田使用氟乐灵进行化除大大提高了劳动生产率和增加了经济效益。棉田使用氟乐灵,每亩可节省人工除草用工4个,合10元。每亩用2.5两氟乐灵,药费仅1元,喷药、拌土机械作业费0.55元,化除一亩地合计仅1.55元。每亩化除比人工除草节约8.45元。全局30.29万亩棉田可节约成本255.95万元。棉田使用氟乐灵的增产效果也极为显著,与人工除草相比可增产1—2成。
Trifluralin herbicide (referring to 48% emulsion, the same below) has been widely applied and popularized in cotton field of Jiangsu Land Reclamation System since 1980. Last year, its area of use reached 302,900 mu, accounting for 94.62% of the total area of cotton land. The use of trifluralin in cotton fields has greatly increased labor productivity and increased economic benefits. Trifluralin cotton field, per acre can save artificial weeding 4, together 10 yuan. 2.5 Trifluralin per mu, only 1 yuan drug costs, spraying, mixing machinery costs 0.55 yuan, in addition to a total of only 1.55 yuan a mu. In addition to save 8.45 yuan per mu than artificial weeding. Global 302,900 acres of cotton fields can cost 2.5595 million yuan. The effect of trifluralin in cotton field is also very significant, which can increase 1-2% compared with artificial weeding.
