The invention discloses a cotton
coating type rooting agent as well as a preparation method and an application thereof. The composition is prepared from the following components in percentage by weight: 0.001 to 1 percent of
brassinolide compound, 0.003 to 3 percent of
nitazoxanide, 0.005 to 5 percent of Brassinogen essence, 0.01 to 1.5 percent of
mannitol, 0.1 to 5 percent of
antioxidant 1010, 0.5 to 10 percent of oat B-
glucan, 5 percent of
composite film-forming agent and the balance of water. The cotton seed
coating agent is specially used for cotton seed emergence and
seedling rooting andgrowth, roots of cotton seeds are continuously stimulated to root under the protection of the
coating agent, and therefore the effects of strengthening roots and seedlings are achieved. The seed coating agent is good in film-forming property, uniform in coating, low in shedding rate and very simple and convenient to operate, can continuously act on roots after
seedling emergence, can promote rootstrengthening, stable growth and early emergence of seedlings during field direct seeding, and can promote rooting and rooting of the seedlings and shorten
seedling recovery during seedling
transplantation; therefore, the effects of high efficiency and labor saving are achieved.
