今年我省主要稻区,由于严重缺水,要采取集中用水晚泡田和插秧后间歇灌溉等措施,预计杂草发生量会比往年多,为此在本田化学除草方面应注意以下几点: 1.除草醚封闭在杂草严重地区,用除草醚实行插前插后两次封闭,是消灭草荒的有效措施。根据今年泡田晚及整地和插秧间隙时间短的特点,旱插秧田块,杂草萌发可能多在插秧之后,因此要实行插后封闭;晚插秧田块,杂草可能发生在插秧之前,可实行插前封闭。
This year, the major rice-growing areas in our province, due to severe water shortages, are expected to take more measures such as concentrated soaking with water and later intermittent irrigation after transplanting. We expect that more weeds will be generated than in previous years. Therefore, we should pay attention to the following points in Honda chemical weed control: 1. Weed-ether closed in a serious weed area, with the weeding plug inserted twice after the closure is an effective measure to eliminate grass shortage. According to the bubble soaked late this year and planting and transplanting a short gap between the characteristics of drought-tolerant seedling blocks, weeds may germinate after transplanting, so the implementation of plug-in closure; Late planting seedlings, weeds may occur before transplanting, may The implementation of plug before the closure.
