Abstract
The invention provides a cotton root regrowth-type growth promoter and a preparation method thereof. The promoter is prepared from following main components: a rooting conditioning agent, a cell excipient and gibberellin with the aid of a water-retaining agent, an adhesive, high-concentration ethanol, tap water and dry sand. The rooting conditioning agent is one or more selected from sodium naphthalene-1-acetate and sodium 3-indolebutyrate. The cell excipient is one or more selected from sodium nitrophenolate and potassium nitrophenolate. The promoter is capable of regaining cotton root activity, promoting root regrowth, promoting extension of newborn root, increasing the fertilizer utilization rate, promoting growth of the overground part, preventing premature senescence and increasing the output.
