以高粱晋糯3号为材料,采用室内生物测定方法,研究安全剂奈安和环丙磺酰胺减轻烟嘧磺隆残留对高粱的药害作用。结果表明,随着土壤中烟嘧磺隆浓度的增大,高粱的生长受到抑制,喷施环丙磺酰胺和奈安后可在一定程度上减轻烟嘧磺隆对高粱生长的影响;当土壤中烟嘧磺隆有效成分残留量为4 g/hm~2时,环丙磺酰胺喷施量为8 mg/kg、奈安喷施量为10~15 g/kg时,药害症状缓解,解毒效果最好。
Using sorghum Jinyou No.3 as material, indoor bioassay method was used to study the effect of safener, nene and cyprosulfamide on the phytotoxicity of nicosulfuron residues to sorghum. The results showed that with the increase of nicosulfuron concentration in the soil, the growth of sorghum was inhibited, and the effects of nicosulfuron on the sorghum growth could be alleviated to a certain extent by spraying cyproterone and neanzine. When soil When the residual content of nicosulfuron residues was 4 g / hm ~ 2, the spraying dose of cyclopropanesulfonamide was 8 mg / kg and the spraying dose of neona was 10 ~ 15 g / kg, The best detoxification effect.
