The invention discloses a cultivation method for coix coix sloping land with moisture conservation, drought resistance and weed suppression. The method uses yellow clay with strong moisture retention to wrap the seeds, which can reduce the evaporation of seed kernel water when the seeds germinate, and can fully absorb the soil when it rains. The moisture in the seed enhances the drought resistance ability of the seed. Simultaneously, in the present invention, the seeds are covered with side film, which can effectively reduce water loss in the soil and maintain soil moisture.
