为稻茬免耕移栽油菜田科学使用除草剂提供依据,采用41%草甘膦异丙铵盐与200g/L百草枯水剂对稻茬免耕油菜进行了田间试验,研究了其对稻茬免耕油菜生长发育的影响。结果表明,41%草甘膦异丙胺盐水剂在施药当天、药后1~4d移栽,油菜苗均出现药害症状,特别是施药当天及药后1~2d移栽油菜苗药害最重,应间隔5d后移栽药害较轻;200g/L百草枯水剂可以在施药当天移栽油菜苗,但最好在药后第2天移栽油菜最为安全。
In order to provide basis for scientific use of herbicides in no-tillage and transplanting rapeseed field in paddy field, field experiments on no-tillage oilseed rape with 41% glyphosate isopropylammonium salt and 200g / L paraquat were conducted. Effects of Crop Cultivation on the Growth and Development of Rape. The results showed that 41% of the glyphosate isopropylamine salt solution was transplanted on the day of application and 1 to 4 days after the drug treatment, and all the rape seedlings showed the symptoms of pesticide damage, especially on the day of application and 1 ~ 2 days after transplanting The heaviest, should be spaced 5d after the transplanting less harmful; 200g / L Paraquat can transplanting rape seedlings on the day of spraying, but the best transplanting rape on the first 2 days after the drug is the safest.
