为了减少和防止西瓜施用化学除草剂的失误,在施用技术上应注意如下几个问题。一、正确选择除草剂。西瓜生产上可用的除草剂品种很多,最常用的有48%氟乐灵乳油、33%除草通乳油、48%地乐胺乳油、12.5%盖草能乳油、15%稳杀得乳油、15%精稳杀得乳油、48%拉索乳油、10%禾草克乳油等。二、严格把握施用剂量。48%氟乐灵每亩用量75～125毫升,33%除草通每亩80～130毫升,48%地乐胺每亩200毫升,12.5%盖草能每亩65～150毫升,15%稳杀得每亩75～130毫升,15%精稳杀得每亩 In order to reduce and prevent mistreatment of chemical herbicide mistakes in the application of technology should pay attention to the following questions. First, the correct choice of herbicides. Watermelon production available on the many varieties of herbicides, the most commonly used 48% trifluralin, 33% weeding pass cream, 48% toxetil EC, 12.5% ​​capitatum EC, 15% stabilized EC cream, 15% Stably killed EC, 48% cable EC, 10% EC grass EC. Second, strictly control the dose. 48% of the trifluralin 75 ~ 125 ml per acre, 33% weed pass 80 ~ 130 ml per acre, 48% 75 to 130 ml per acre, 15% fine killed every acre
