扑草净是一种较为有效的内吸性除草剂,可用作水稻直播田、秧田播前施药和插秧后撒毒土,防除多种杂草。扑草净溶解度较大,如使用浓度过大,很易对水稻产生药害。一旦发生药害,轻者稻苗生长缓慢,分蘖减少;重者稻苗大量死亡,即使重插补苗也不能存活。现根据我们的实践,谈一谈水稻扑草净药害后的补救措施。 Prometryne is a more effective systemic herbicide, can be used as direct seeding rice field, sowing before planting and transplanting poisonous soil after planting, control a variety of weeds. Prometryne net solubility, such as the use of concentration is too large, it is easy to produce phytotoxicity on rice. In the event of injury, light seedlings grow slowly, reduce tillers; severe heavy death of rice seedlings, even if the replanted seedling can not survive. Now according to our practice, talk about rice prometryne remedy after injury.
