The invention discloses a preparation method and application of a micro-capsule suspension-suspending agent containing s-metolachlor and flumioxazin. The preparation method solves the problem that the suspension rate of flumioxazin is easily reduced when a s-metolachlor micro-capsule suspending agent and a flumioxazin suspending agent are mixed. The micro-capsule suspension-suspending agent containing s-metolachlor and flumioxazin can effectively prevent and control annual gramineous and broadleaf weeds on soybeans, peanuts, sunflowers, cotton and sugarcanes through soil sealing treatment after sowing and before seedling emergence, and the crop yield is increased. 本发明公开了一种含精异丙甲草胺和丙炔氟草胺的微囊悬浮-悬浮剂的制备方法和应用，本发明制备方法解决了精异丙甲草胺微囊悬浮剂与丙炔氟草胺悬浮剂混合时容易导致丙炔氟草胺悬浮率降低的问题。本发明的精异丙甲草胺和丙炔氟草胺的微囊悬浮-悬浮剂在播后苗前土壤封闭处理可有效防治大豆、花生、向日葵、棉花、甘蔗上的一年生禾本科及阔叶杂草，提高作物产量。
