[目的]测定无机盐助剂、油类助剂和有机硅助剂分别与480 g/L灭草松水剂混用对防除野慈姑的增效作用。[方法]通过室内生物活性测定,将3种喷雾助剂按不同剂量和配比与480 g/L灭草松水剂混用,测定对野慈姑的毒力。[结果]1.5 L/hm~2油类助剂英伏腾分别与30、80、160 mmol/L硫酸铵混用时,对野慈姑的鲜重防效分别为74.9%、75.8%和76.8%,增效幅度均达到43.0%以上。[结论]初步确定480 g/L灭草松水剂与硫酸铵和英伏腾混用对野慈姑有明显的增效作用。
[Objective] The research aimed to determine the synergistic effect of inorganic salt additives, oil additives and organosilicon additives with 480 g / [Method] The toxicity of 3 kinds of spray auxiliaries was mixed with 480 g / L Methomyl pine in different doses and proportions through indoor bioassay. [Result] The results showed that the fresh weight control of wild arrowheads was 74.9%, 75.8% and 76.8%, respectively, when mixed with 30, 80 and 160 mmol / L ammonium sulfate at 1.5 L / hm ~ Efficiency gains reached more than 43.0%. [Conclusion] The preliminary synergistic effect of 480 g / L imazapyr in combination with Ammonium sulfate and British Voltaton was observed.
