湖北五三农场一九六四年开始化学除草试验,取得经验后逐年增大化学除草面积、扩大作物种类,收到了良好效果。到一九七九年,化学除草面积达十二万亩次,占整个耕地面积的百分之八十五,作物有水稻、棉花、大豆、玉米、高粱、花生、甘蔗等。经使用化学除草剂的田,一般一年生杂草可消灭百分之八、九十,省工增产。十多年来,我场共引进试用了三十多种除草剂,经过筛选已应用于大田的有敌稗、五氯酚钠,除草醚、二甲四氯、敌草隆,其它种类也进行了较大面积示范和小区田
On May 19, Hubei Peasant Farm started the chemical weed control experiment in 1964. After gaining experience, it gradually increased the area of chemical weed control and expanded the crop species with good results. By 1979, the chemical weed control area will be 120,000 mu, accounting for 85% of the total arable land. Crops include rice, cotton, soybean, corn, sorghum, peanuts, sugar cane and so on. By the use of chemical herbicide in the field, generally annual weeds can eliminate eight percent, ninety, provincial labor productivity. For more than a decade, we have introduced more than thirty herbicides tested in our field. After screening, we have used propanil, sodium pentachlorophenol, weed, etoposide and diuron, and other species have also been applied to the field A large area of demonstration and plot Tian
