夏玉米田极易形成草荒,严重影响玉米产量。为了寻找夏玉米田的优良除草剂,1986～1987年在室内试验基础上,经田间试验进一步证明西玛津、都尔、丁草胺等除草剂适用于夏玉米田除草。几种除草剂对玉米出苗、植株生长等均无不良影响。一、材料和方法 (一)供试药剂和使用剂量 (1)72％都尔乳油,150克/亩(瑞士汽巴—嘉基公司);(2)48％甲草胺乳油,200克/亩(美国孟山都公司);(3)60％丁草胺乳油,150克/亩(广州农药厂);(4)
Summer corn field is extremely easy to form grassland, seriously affecting the yield of corn. In order to find the excellent herbicide in summer maize field, herbicides such as simazine, doyle, butachlor and so on were further proved to be suitable for weeding in summer maize field through field experiments from 1986 to 1987. Several herbicides on corn emergence, plant growth, etc. no adverse effects. Materials and methods (a) The test agents and the use of dose (1) 72% Seoul cream, 150 g / acre (Swiss Ciba - Jiaji company); (2) 48% (Monsanto, USA); (3) 60% Butachlor EC, 150 g / acre (Guangzhou Pesticide Factory); (4)
