农田化学除草是农业生产上的一项新技术。使用化学除草剂能消除杂草危害,大量节省劳力,减轻劳动强度,确保农作物丰收。1973年我场开始在棉地试用化学除草,1977年使用化学除草的棉田扩大到200亩,1979年又扩大到400亩,并在34亩杂优秧田和55亩二季晚稻本田使用了化学除草剂,均获得了显著效果。这一年,全场共节约中耕除草的劳动力约4,600个,并为稻、棉增产创造了条件。现将几年来我场试验化学除草的情况总结如下。 Farmland chemical weeding is a new technology in agricultural production. The use of chemical herbicides can eliminate weed hazards, save a lot of labor, reduce labor intensity and ensure the harvest of crops. In 1973, we started to use chemical weed control in the cotton field. In 1977, we used chemical weedy cotton fields to expand to 200 mu and in 1979 to 400 mu. We also used chemical herbicides on 34 mu of miscellaneous seedlings and 55 mu of sedentary late-seasoned rice Honda , Have achieved remarkable results. During the year, about 4,600 labor for cultivating and cultivating weeds was cut off and the conditions for paddy and cotton production were created. Now we test the field of chemical weeding the past few years are summarized below.
