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. When it rains, the rainwater flows into the seed rows on both sides through the film, improving the utilization rate of rainwater. Moreover, the black film is used to cover the weeds under the film to lose the photosynthetic conditions. At the same time, the film is used to physically block the pressure, so that the weeds cannot grow normally, which effectively saves the cost of weeding in the later stage. In addition, in the present invention, the seed row is covered with corn stalks, which can reduce the evaporation of soil moisture in the seed row and maintain soil moisture.
