The present application relates to the technical field of agricultural application, in particular to a kind of industrial hemp male luring agent and its preparation method and application.The present application uses the common chemical
reagent alpha-amino
isobutyric acid (AIB) and
gibberellin GA3 as effective component and prepares male luring agent, compared with existing male luring agent
silver thiosulfate (STS),
raw material is more easily obtained, cost is more inexpensive, use is
safer, effect is more optimal, has the potential for large-scale production practice.Using the male luring agent proposed in the present application to spray the
inflorescence parts of industrial hemp female plants at the beginning of flowering can induce female plants to be male, and produce fertile
pollen.The
pollen produced by the induced male plants is used to pollinate the inflorescences of
normal female plants, which can produce seeds and obtain all-female seeds, which are used for industrial hemp female seed production.
