为了提高棉田化学除草效果,我所从1979～1981年进行了棉花苗期定向喷雾试验,并在海河乡跃华8队搞了百亩棉花苗期定向喷雾示范,均取得了显著效果。一、供试药剂: 25％除草醚、25％绿麦隆(上海红卫农药厂产品),25％敌草隆(无锡惠山农药厂产品),40％黄草灵(镇江农药厂产品),48％氟乐灵和43％拉索(意大利产品)。二、施药剂量: 单用:48％氟乐灵100克/亩,43％拉索200克/亩,40％黄草灵200克/亩,25％绿麦
In order to improve the chemical weed control effect in cotton field, we carried out the directional seedling spraying experiment from 1979 to 1981 and achieved the remarkable results in directional spray demonstration of Baimu 8 in Haihe Township. First, the test agents: 25% of weeding ether, 25% chlorotoluron (Shanghai Hongwei Pesticide Products), 25% Diuron (Wuxi Huishan Pesticide Products), 40% Huangcao Ling (Zhenjiang Pesticide Products), 48 % Trifluralin and 43% cable (Italian product). Second, the application dose: single use: 48% trifluralin 100 g / acre, 43% cable 200 g / acre, 40% Huangcao Ling 200 g / acre, 25%
